Definitions
- the present invention relates to a dump system for use with a solid removal system in the oil and gas industry.
- Such traps can require a specific or varying frequency of emptying. This removal of solids is done from time to time to ensure operation of the trap at maximum capacity. How often they need emptying varies, however, dependent upon where they are in their operating cycle. For example, at start up there is commonly a significant amount of solids which require removal, but under steady operation the solid build-up is often not as great, requiring a less frequent removal.
- the present invention seeks to improve the operation of dumping systems for use with such solids traps to improve their reliability as well as address safety.
- a solids dump system for connection to a solids removal system for removing solids from the flow in a hydrocarbon processing facility, the dump system comprising: a programmable controller; and at least one valve connected to the outlet of the solids removal system, wherein the programmable controller is arranged to operate the valve(s) at selected timings during operating the removal system and/or upon receipt of trigger signals from level sensors within the solids removal system.
- the present invention it is possible to vary the timing of the solids removal cycle dependent upon the operating cycle of the trap and the well system as a whole such that there is not excessive build-up of solids material within the trap yet also it is possible to avoid excessive operation of the dumping system.
- control the operation on the basis of level sensors within the trap, the level sensors positioned at upper and lower levels for initiating operation when the upper level sensor detects the trap is full, and the lower level sensor operating to deactivate when it is determined that the track has been emptied to an appropriate level.
- Figure 1 is a schematic diagram of the system of the present invention for attachment to a known solids trap
- Figure 2 is a flow diagram showing an operation of a system of the invention.
- Figure 3 is a second flow diagram showing an alternative or complementary operation of a system of the invention.
- a dump system 1 there is arranged to be attached, in use, to a material, such as sand, trap vessel 2.
- the sand trap vessel 2 may be of the cylindrical ( in vertical or horizontal orientation) or spherical type.
- the spherical type has benefits however in terms of ensuring good trapping of sand because of the larger circumference enables lower velocities to improve sand settlement and trapping.
- upper and lower material level sensors 21, 22 are attached to the sand trap vessel 2. Such sensors should be configured so that their inlets are facing downwards to avoid clogging and are configured to detect the difference between material such as sand and water or other liquid.
- the dump system 1 has an inlet connector 3 which connects to an outlet (not shown) of the sand trap vessel 2 via a relatively standard union-style connector.
- the inlet 3 of the dump system 1 is connected to a manually operated isolation valve 4 which in turn is connected via pipework 5 to an automated isolation valve 6.
- the automated isolation valve 6 is then connected to an automated choke 7 and this is in turn connected to a manually operated isolation valve 8.
- the outlet of the manually operated isolation valve 8 is connected to an outlet 9 from the dump system, that outlet 9 normally being connected, in use to a storage tank or pit into which solids are passed. Again, the outlet 9 may be connected to any further components via a union-style connector for ease and standardisation of connection.
- Upstream and downstream pressure transmitters 10, 11 are provided to provide an indication of pressure at the inlet 3 and outlet 9 to a control component 12.
- the control component 12 is arranged to receive data from the upstream and downstream pressure transmitters 10, 11, as well as time information from a clock and programmable control data from an operator or operating system.
- the programmable control component 12 provides control output to the automated isolation valve 6 and automated choke 7 to provide optimised operation of the dump system 1 as will be described below.
- the whole system 1 can be mounted on a movable skid (not shown) for ease of movement from site to site as well as for ease of installation. This also ensures a small footprint for the device.
- an activation trigger is provided to the programmable controller either via a timer after a predetermined time period, or by an activation component triggered by initial start-up of the sand trap vessel 2.
- the programmable controller 12 then monitors the upstream and downstream pressures to ensure that they are at acceptable values. If they are not at acceptable values then a fault indication can be provided to an operator. If the pressures are at acceptable values the program controller controls the automated isolation valve 6 and choke valve 7 to allow material to be passed out from the sand trap vessel 2 through the dump system 1 and out of the outlet 9.
- the cycle opens by the opening of the choke valve 7 followed by the opening of plug valve 6.
- the upstream and downstream pressures are monitored and an increase in pressure should be seen on the downstream pressure monitor 1 1. If this does not happen than an alarm condition is indicated.
- the plug isolation valve 6 is then closed followed by the choke valve 7. Again, pressures are monitored and a pressure drop should be seen on the downstream pressure sensor 11. Again, if this is not the case then an alarm condition is indicated.
- the programmable controller receives signals from material levels sensors 21 , 22 positioned in the sand trap vessel.
- An upper sensor 21 detects when the sand trap vessel is full and activates the system.
- the lower level sensor 22 provides signal to activate the closing operation as described in Figure 2.
- the material level sensors 21, 22 are oriented so that their sensing aperture is facing downwards to prevent clogging with sand. They are configured to detect the presence of sand in a fluid such as water, with the upper sensor 21 configured to trigger the system when sand is detected as being present, and the lower sensor 22 being configured to commence the second stage of operation of the system when it is detected that sand isn't present after triggering of the upper sensor 21.
- the system operates only when absolutely necessary with a dynamic or on-demand cycle, which can assist in reducing further the wear on the system and its components, increasing operational lifetime and reducing maintenance requirements.
- this system can be operated to open the plug valve 6 prior to opening the choke valve 7 and during the closing process to close the choke valve 7 prior to closing the plug valve 6, would be the same as the example of Figure 2.
- Such a configuration can, in certain circumstances, have benefits in terms of it controlling the wear caused by sand and other contaminants in the system such that the choke valve 7 receives more damage but reduces damage on the plug valve 6.
- the choke valve 7 is more readily replaceable and can cope with higher levels of damage this may have particular maintenance and product lifetime benefits.
- the system may be configured such that a secondary dump system is provided and attached in parallel to the outlet of the sand trap vessel 2. Under alarm conditions the programmable controller 12 can then be configured to direct flow via an additional valve (not shown) to the second dump system so that operation is uninterrupted until a manual investigation of the alarm condition can be provided.
- a choke valve 7 is particularly suited to controlling pressure drop and velocity downstream of the choke valve, ensuring optimised operation of the system.
- the manual valve 4 and manual valve 8 are provided to allow cut-off of the system during repair and replacement of the other components such as the automated choke and plug valves 7, 6. Furthermore, by using interconnections between individual components which are straightforward in the form of union connections, it is possible to develop a system which is relatively standardised and in which components can be removed and replaced relatively easily improving use of maintenance and operation.
