Abstract
A method for processing hydrocarbon fluids comprising a processing stage in a process of removing oxygenates, such as glycols or ethers from the hydrocarbon fluids. The processing stage comprises: during loading of the hydrocarbon fluids 262 onto a transport vessel 295, or while the hydrocarbon fluids are located on a transport vessel, injecting water into the hydrocarbon fluids 214, to thereby disperse the injected water in the hydrocarbon fluids. The first injection point may be in conduit transporting Hydrocarbons to the vessel from a offshore facility such as a production platform or vessel. A second injection point may be on a conduit between two containers within the vessel. The water injected hydrocarbon fluid may be retained to allow the water contaminated with oxygenates to separate from the hydrocarbon phase which then may be removed.
Description
METHOD FOR PROCESSING HYDROCARBONS FOR THE REMOVAL OF OXYGENATES Technical Field The present invention relates to the processing of hydrocarbons, and in particular the processing of hydrocarbon fluids for the removal of oxygenates from the hydrocarbon fluids.
Background
Hydrocarbon fluids are typically produced from a reservoir in a formation, and are conveyed from the reservoir via a production well. Such hydrocarbon fluids typically contain a variety of impurities and/or foreign substances. Such impurities and/or foreign substances include water, salts (which may be contained in the water), gases, organometallic compounds and organic acids, oxygenates and solids.
Foreign substances may also be added to the hydrocarbon fluids to facilitate transport away from the well, and/or to prevent the formation of undesirable substances. For example, water may be added to heavy hydrocarbon liquids to reduce the viscosity of the fluids and thereby facilitate transport through a flow line. Another example is the addition of oxygenates such as monoethylene glycol (MEG) or triethylene glycol (TEG) to hydrocarbon fluids. Hydrates are ice-like solids that can form when hydrocarbon gases and water combine under certain pressure and temperature conditions. Hydrates may form while hydrocarbon fluids (usually comprising significant amounts of natural gas) are transported away from the well in a flowline e.g. to a processing facility, and the hydrates may block the flowline. The MEG or TEG provides a dehydrating effect, which prevents the formation of hydrates. MEG or TEG is therefore added to the hydrocarbon fluids at or near the wellhead, i.e. before the fluids are transported away from the well in a flowline, to prevent blockage of the flowline by hydrates.
To mitigate potential damage to equipment and to comply with regulations and/or customer requirements, it is necessary to remove, reduce or transform the impurities and/or foreign substances before an end product is sold to customers. To achieve this, the hydrocarbon fluids are typically processed at a processing facility, and then refined at a refinery. Typical processing steps performed at the processing facility include gas/liquid separation, oil/water separation, and desalting. Oxygenates typically follow the water phase, and therefore existing processing techniques have aimed to remove oxygenates in the water separation processing stages.
Summary
It is an object of the present invention to overcome or at least mitigate the problems identified above.
In accordance with an aspect of the present invention, there is provided a method for processing hydrocarbon fluids, the method comprising a processing stage in a process of removing oxygenates from the hydrocarbon fluids, the processing stage comprising: during loading of the hydrocarbon fluids onto a transport vessel, or while the hydrocarbon fluids are located on a transport vessel, injecting water into the hydrocarbon fluids, to thereby disperse the injected water in the hydrocarbon fluids.
The water may be injected into the hydrocarbon fluids at a first injection point along a conduit carrying the hydrocarbon fluids. The conduit may be conveying the hydrocarbon fluids from a surface structure onto the transport vessel, or the conduit may be conveying the hydrocarbon fluids between a first container and a second container located on the transport vessel.
The injected water may be dispersed into the hydrocarbon fluids using a static mixer.
The transport vessel may be transporting the hydrocarbon fluids from an offshore surface structure for processing at an onshore facility. The offshore surface structure may be a production platform or vessel. The onshore facility may comprise a refinery and/or a processing facility.
The method may further comprise, after the water has been injected into the hydrocarbon fluids, retaining the dispersion in a container to allow a contaminated water phase containing oxygenates to separate from a hydrocarbon phase under the influence of gravity.
The method may further comprise, after the water has been injected into the hydrocarbon fluids, separating a contaminated water phase containing oxygenates from a hydrocarbon phase using a dedicated separation system located on the transport vessel.
The method may further comprise, after the contaminated water phase has been separated from the hydrocarbon phase, removing the contaminated phase.
Embodiments of the invention will now be described by way of example only and with reference to the accompanying drawings, in which:

Detailed description
The presence of oxygenates such as MEG and/or TEG in hydrocarbon fluids can cause problems in refinery processes, and market requirements for low levels of oxygenates in final hydrocarbon products have become increasingly strict (e.g. an upper limit of 10 ppm of oxygenates).
It has been found that existing oxygenate removal processes, i.e. using existing water-separation processing stages, may not remove enough oxygenates to prevent such refinery problems or to comply with market requirements. A processing facility typically includes multiple separation stages, e.g. at least a first, high-pressure, three-phase separation stage (to separate oil, water and gas); a second, lower-pressure gas separation stage; and a final water-separation stage before the hydrocarbon fluids leave the processing facility for transport to a refinery. The final water-separation stage is typically performed at a high temperature to remove as much water as possible. The inventors have realised that at such high temperatures the oxygenates in the remaining water (which is typically at least partly present as an emulsion in the oil phase) migrate into the oil phase of the hydrocarbon fluids. The oxygenates in the oil phase will not be removed with the waste water in the final water-separation stage, and will therefore remain in the hydrocarbon fluids that are transported to the refinery. The processing facility may be located on an offshore platform or facility, such that processing stages, e.g. the above-referenced processing stages, are performed before the hydrocarbons are transported on a vessel, e.g. a shuttle tanker, to a refinery. Alternatively, hydrocarbons may be transported in a vessel, e.g. a shuttle tanker, before any processing stages are performed on the hydrocarbons, such that processing stages, e.g. the above-referenced processing stages, are performed onshore.
The present invention solves the above referenced problem by, during loading of the hydrocarbon fluids onto a transport vessel, e.g. a shuttle tanker for transporting the hydrocarbon fluids from an offshore platform or facility to an onshore facility, or while the hydrocarbon fluids are located on a transport vessel, injecting water into the hydrocarbon fluids, to thereby disperse the injected water in the hydrocarbon fluids. The hydrocarbon fluids are, or comprise, e.g. crude oil or condensate. In an embodiment, the water is injected using a dedicated wash water pump and mixer, e.g. a static mixer. The injection point is on the transport vessel, or alternatively at any point along a conduit conveying the hydrocarbon fluids onto the transport vessel.
The injected water will contact water in the hydrocarbon fluids that contains the oxygenates, and then by separating a resultant water phase from the hydrocarbon phase, the contaminant oxygenates can be removed. In an embodiment, the retention time on the transport vessel is used to achieve separation of the phases under the influence of gravity, and the contaminated water phase is then moved to a separate container on the transport vessel, or the contaminated water phase is removed at an onshore facility. Alternatively or additionally, a dedicated separation system is present on the transport vessel to separate the contaminated water from the hydrocarbon fluids, using methods known in the art (e.g. centrifugal separation).
The injected water will dilute the contaminants present in the hydrocarbon fluids, and will thereby facilitate the later removal of the contaminants in the separation process. The retention time on the shuttle tanker increases the ability of the wash water to contact the contaminant-containing water in the hydrocarbons, and thereby increases the efficiency of removing the contaminants. The present invention provides a low-cost way to improve the efficiency of removing oxygenates from hydrocarbon fluids.
Figure 1 shows an overview of a hydrocarbon production system. A production well 130 extends through a subsurface formation of the Earth 150. The well is e.g. a natural gas and condensate production well. Hydrocarbon fluids 125, e.g. lightweight liquid hydrocarbons and/or natural gas and condensate, are extracted from a reservoir 120 and are conveyed out of the well 130 as indicated by arrow 160. The hydrocarbon fluids 125 are typically extracted out of the well 130 in production tubing. The hydrocarbon fluids extracted from the reservoir may contain impurities and/or foreign substances including e.g. water, salts (which may be contained in the water), gases, organometallic compounds and organic acids, oxygenates and/or solids. The oxygenates may comprise monoethylene glycol (MEG) and/or triethylene glycol (TEG).
Once removed from the well 130, the hydrocarbon fluids are routed via wellhead 140, and are conveyed from wellhead 140 in flowline 180 to a processing facility 100 located on a surface structure 190, in the direction indicated by arrow 161. The surface structure 190 is e.g. a platform such as a production platform, a vessel such as a floating production storage and offloading (FPSO) vessel, or any other suitable surface installation, located at the sea surface 155. In the schematic illustration of Figure 1, the flowline 180 includes a substantially vertical riser section, and other sections on the surface structure. In reality, these separate sections may be different types of conduit separated by structures, e.g. the section of the flowline along the seabed may terminate at a riser base, and the vertical section of the flowline may be a riser that terminates at the surface structure 190. Arrow 170 indicates a point at which, in some embodiments, foreign substances are injected into the hydrocarbon fluids, when the hydrocarbon fluids are contained in the wellhead 140 or in flowline 180, to facilitate transport of the hydrocarbon fluids, and/or to prevent the formation of hydrates. The oxygenate injection point 170 is at or near the wellhead. In an embodiment, oxygenates are injected into the hydrocarbon fluids at the injection point to prevent the formation of hydrates in the hydrocarbon fluids during their transport between the wellhead 140 and the processing facility 100, where the oxygenates are or comprise e.g. MEG and/or TEG. The hydrocarbon fluids are processed at processing facility 100, and the processed hydrocarbon fluids are then loaded onto a transport vessel 195, e.g. a shuttle tanker, as indicated by arrow 162. The hydrocarbons in the hydrocarbon fluids are e.g. light-weight liquid hydrocarbons or condensate.
In an embodiment, there is no processing facility 100 located on the surface structure 190, and the hydrocarbon fluids are conveyed from the well and loaded onto the transport vessel 195 without any processing stages being performed at a dedicated processing facility. In this case, the processing stages that would have been performed at processing facility 100 in Figure 1 are typically performed at an onshore processing facility.
During loading of the hydrocarbon fluids onto the transport vessel 195, or while the hydrocarbon fluids are located on the transport vessel 195, water is injected into the hydrocarbon fluids, to thereby disperse the injected water in the hydrocarbon fluids. The injection point is on the transport vessel, or alternatively at any point along a conduit conveying the hydrocarbon fluids onto the transport vessel. The details of the injection process are not shown in Figure 1, but are set out below in relation to Figures 2 and 3.
In Figure 2, like features from Figure 1 are indicated by reference numerals incremented by one hundred. The hydrocarbon fluids are conveyed from the surface structure onto the transport vessel 295, i.e. are loaded onto the transport vessel 295, in a conduit as illustrated by the arrow 262. As set out above, in an embodiment the hydrocarbon fluids have already been subjected to processing stages (e.g. water and/or gas separation) on the surface structure, or in an alternative embodiment have not yet been subjected to any processing stages at a dedicated offshore processing facility. In the embodiment shown in Figure 2, water is injected into the hydrocarbon fluids at a first injection point 214. The injected water will be dispersed into the hydrocarbon fluids, and at least a portion of the injected water will subsequently contact water in the hydrocarbon fluids that contains the oxygenates. The injected water will dilute the contaminants present in the hydrocarbon fluids, and will therefore make it easier to remove the contaminated water phase in a later processing stage.
In an embodiment, a static mixer is located at or near the first injection point 214, in (or at the end of) a conduit carrying the water to be injected. The static mixer will cause the injected water to be dispersed more finely into the hydrocarbon fluids, which will increase the chances of the injected water contacting the water in the hydrocarbon fluids that contains the oxygenates, and will thereby increase the efficiency of removing the oxygenates from the hydrocarbon fluids. Static mixers are known in the art, and any suitable static mixer can be used to achieve this.
In Figure 3, like features from Figure 2 are indicated by reference numerals incremented by one hundred. Figure 3 illustrates a process that may be performed in addition to, or as an alternative to, the process illustrated in Figure 2.
In the embodiment shown in Figure 3, the transport vessel 395 includes a first container 311 for containing the hydrocarbon fluids. The hydrocarbon fluids are conveyed from the first container 311 to a second container 313 in a conduit 312, using any suitable method, e.g. a pump. Water is injected into the hydrocarbon fluids at a second injection point 316, while the hydrocarbon fluids are contained in the conduit 312. In an embodiment, a static mixer is located at or near the second injection point 316, in (or at the end of) a conduit carrying the water to be injected. The static mixer will cause the injected water to be dispersed more finely into the hydrocarbon fluids, which will increase the chances of the injected water contacting the water in the hydrocarbon fluids that contains the oxygenates, and will thereby increase the efficiency of removing the oxygenates from the hydrocarbon fluids. Any suitable static mixer can be used to achieve this.
After the water is injected as shown in Figure 2, and/or as shown in Figure 3, the dispersion comprising the hydrocarbon fluids and injected water will be held in a tank on the transport vessel. At least a portion of the injected water will contact water in the hydrocarbon fluids that contains the oxygenates. Over time, and under the influence of gravity, the water phase, which will contain oxygenate contaminants, will separate from the hydrocarbon phase in the tank, and the contaminated water phase can be moved to a different tank using known methods, where the different tank is located on the transport vessel or onshore. Alternatively, a dedicated separation system (not shown in the Figures) located on the transport vessel is used to separate the water phase from the hydrocarbon phase. The dedicated separation system may use any suitable separation method, e.g. centrifugal and/or heat-based separation methods. It is possible that finely dispersed water that contains oxygenates and that has not been contacted by the injected water will remain in the hydrocarbon phase, but the present invention will increase the amount of water containing oxygenates that can be removed from the hydrocarbon fluids.
Figure 4 shows a high level flow diagram illustrating a method in accordance with the invention. The invention relates to a method for processing hydrocarbon fluids, the method comprising a processing stage in a process of removing oxygenates from the hydrocarbon fluids. In step 402, during loading of hydrocarbon fluids onto a transport vessel, or while hydrocarbon fluids are located on a transport vessel, water is injected into the hydrocarbon fluids, to thereby disperse the injected water in the hydrocarbon fluids.
It will be appreciated by the person of skill in the art that various modifications may be made to the above described embodiments without departing from the scope of the present invention.
