Abstract
The present invention relates to a small-type skid-mounted natural gas light hydrocarbon recovering method for petroligenic natural gas gathering process. It adopts skid-mounted mode, and utilizes the natural gas compressor, refrigerator and auxiliary refrigerating system mounted on the skid and trailer which can be flexibly moved to produce liquefied gas, light oil, mixed hydrocarbon and dry gas product. It utilizes dehydration device and adopts molecular sieve to adsorb removed water or methyl alcohol drop-injection method to prevent formation of hydrate under the condition of low temperature, and utilizes the fractionation plant to produce liquefied gas, light oil and mixed hydrocarbon product, and the dry gas product can be fed into natural gas gathering system to deliver to exterior or can be used as fuel gas.
Description
Technical field:
The present invention relates to a kind of processing method that is used for oil and gas gathering and transportation technology lighter hydrocarbons recovery.
Background technology:
In the gas gathering and transportation process, for making full use of resource, increase economic efficiency, need reclaim hydrocarbon mixtures such as the ethane in the Sweet natural gas, propane, butane, pentanes, this process is called gas reducing liquid and reclaims, and is commonly referred to lighter hydrocarbons recovery.Product after the lighter hydrocarbons recovery can be divided into ethane, propane, butane, liquefied petroleum gas (LPG) (propane, butane mixture) and light oil.At present, usually the Sweet natural gas methods of light hydrocarbon recovery technology that adopts is comparatively complicated, need to adopt the bigger fixture of some volumes, like this, the Sweet natural gas that can not enter the gas gathering and transportation system for the outlying scattered block of oil-gas field just can not be suitable for, lighter hydrocarbons recovery be can't carry out, the loss or the waste of a large amount of valuable lighter hydrocarbons resources caused.
Summary of the invention:
The object of the present invention is to provide a kind of flexible, easy to use, as can to carry out lighter hydrocarbons recovery small-sized skid Sweet natural gas methods of light hydrocarbon recovery of moving to the Sweet natural gas that outlying scattered block can not enter the gas gathering and transportation system.
Method provided by the invention is to adopt the skid mode, utilization is installed in drag natural gas compressor, refrigerator, the auxiliary cooling system on the sled that can move flexibly and produces liquefied gas, light oil, hydrocarbon mixture and dry gas product, utilize dewatering unit to adopt molecular sieve adsorbing and dewatering or methanol dropping method to prevent the generation of hydrate under the cold condition, utilize fractionation plant to produce liquefied gas, light oil, hydrocarbon mixture product, the dry gas product then can enter the defeated or gas that acts as a fuel outside the gas gathering and transportation system.The technical process of implementing this method is: Sweet natural gas separates supercharging, dry decontamination or notes alcohol, and auxiliary cooling, precooling, the refrigerator refrigeration, fractionation stabilization, dry gas are defeated outward, the product accumulating.During enforcement, the sled piece roping that will be loaded with said apparatus with trailer to outlying scattered block well point with can carry out lighter hydrocarbons recovery after oil gas gas well gas pipeline is connected.
Methods of light hydrocarbon recovery process unit volume provided by the invention is little, can move flexibly, the convenient use, easy to implement, utilize it can be to outlying scattered block, the Sweet natural gas that can not enter gathering system carries out lighter hydrocarbons recovery, makes full use of resource and improves economic and social benefit.
Description of drawings:
Accompanying drawing is a process flow diagram of the present invention.
Embodiment: enforcement of the present invention is illustrated below in conjunction with accompanying drawing.
As shown in the figure: technical process of the present invention is made up of separator 1,6,10,13, compressor 2, water cooler 3,5,15,18, drying tower 4, heat-conducting oil system (or steam system) 7, ice chest 8,12, ammonia external condensation system 9, refrigerator 11, deethanizing column 14, stabilizer tower 16, reflux pump 17.Its technological process is as follows: after the unstripped gas of outlying scattered block oil gas well enters separator 1 separation, by compressor 2 superchargings, drying tower 4 dry decontaminations or notes alcohol, and after water cooler 3,5, ice chest 8, ammonia external condensation system auxiliary cooling, precooling, enter refrigerator (decompressor) 11 refrigeration; After deethanizing column 14, stabilizer tower 16 fractionation, stable can reclaim respectively and obtain liquefied gas, light oil, hydrocarbon mixture product and dry gas.
Claims (2)
1, a kind of small-sized skid Sweet natural gas methods of light hydrocarbon recovery, it is characterized in that, this method is to adopt the skid mode, utilization is installed in drag natural gas compressor, refrigerator, the auxiliary cooling system on the sled that can move flexibly and produces liquefied gas, light oil, hydrocarbon mixture and dry gas product, utilize dewatering unit to adopt molecular sieve adsorbing and dewatering or methanol dropping method to prevent the generation of hydrate under the cold condition, utilize fractionation plant to produce liquefied gas, light oil, hydrocarbon mixture product, the dry gas product then can enter the defeated or gas that acts as a fuel outside the gas gathering and transportation system.
2, small-sized skid Sweet natural gas methods of light hydrocarbon recovery according to claim 1 is characterized in that the technical process of implementing this method is: Sweet natural gas separates, supercharging, dry decontamination or notes alcohol, auxiliary cooling, precooling, refrigerator refrigeration, fractionation stabilization, dry gas are defeated outward, the product accumulating.
