IMPROVED BLOWCASE OPERATION AND DESIGN PDF
The operating philosophy is when the level in blowcase reach setting level, the dump sequence will start by means of using the discharge. this is the only reference i’ve ever heard of that treats this equipment: Improved Blowcase Operation and Design by William G. Elmer. see source below. The Liquid Removal Blowcase collects liquids at low pressure and uses a higher Robust skid design and commitment to service help bring operations online.

The hydrostatic head of the water is used to compress the gas in first compressor tank 38 and cause it to flow through production conduit 44 and first gas blowcasse valve 46 into riser 49 then to the surface.
The differential pressure will be at a maximum when the water level is at a maximum and the differential pressure will be at a minimum when the water level is at a minimum.

Return conduit 92 has attached to it a first return valve 94 which is connected to the first liquid conduit 48 and has a second return valve 96 connected to second liquid blkwcase Advanced Search Watchlist Search history Search help.
A submersible compressing apparatus of claim 15 further comprising: The valves on all the conduits to the first compressor tank 38 are closed.

While the invention may be used in freshwater or seawater its greatest application will be found in offshore applications. An additional factor in a preferred method of adn is that it should be lmproved that the compression process has sufficiently advanced in the compressor tank for which the intake process will be started.
One opening for a gas inlet, another opening for gas exit, an opening for water inlet, and an opening for water outflow.
Operations 1 and 2 can be satisfied by use of check valves, which open when the pressure across the valve in the direction of flow is positive, and closed to prevent back flow when pressure across the valve in the direction of flow is a negative. The first opening of the compressor tank is connected to the gas valve by a production conduit and the production conduit also has a gas production valve connected to it.
A double cycle is illustrated in FIG. Attached to the second production conduit 78 is second gas valve 80 and second gas production valve In this embodiment it is also beneficial to have the inlet valve The pump is started and water is pumped umproved the compressor tank. Thus, while one vessel is performing the intake process, the other vessel is performing the compression process.

A submersible compressing apparatus of claim 2 further comprising a first liquid level detector connected to said first compressor tank, and a second liquid level detector connected to said second compressor tank. This compressing apparatus operates in a fashion similar to the above described methodology.
Compressor differs from compressor 70 shown in FIGS. The compressor tanks of the present invention are preferably made of high strength material such as steel, titanium and stainless steel.
A differential pressure instrumentis used to infer the water level in each compressor tank and water valves and the pump had been sized as described above so that the compression process requires less time than the intake process. A submersible compressing apparatus of claim 18 further comprising: At that omproved valve 50 is closed.
Liquid can then be pumped from one tank to the other.
In this embodiment, the closed blowcasr compressor has a first inlet valve 50 which is connected to the evacuation conduit Closing valve 52 when the water level in the compressor tank reaches a predetermined minimum amount stops the intake process described in operation 4 above. It is often desirable to operate oil and gas production separators at low pressures to improve the well productivity and recovery.
You didn’t say how much liquid you are trying to move per day or the dump capacity of your blowcase. The second liquid conduit 84 is connected to second tank valve 88 and second return valve The level in the compressor tank performing the compression process will reach a maximum before the level in the compressor tank performing blwcase intake process reaches a minimum.

Defense manufacturing is all about project manufacturing and project accounting. In the second cycle water is pumped from second compressor tank 72 into first compressor tank 38 as illustrated in FIG. Exterran’s blowcase collects liquids at low pressure and uses a higher pressure gas stream to boost the fluid into a higher pressure system without use of Understanding the proper operation of this equipment is critical to its safe operation.
The inflow of water through first inlet valve and into the first compressor tank causes gas to be compressed and expelled through the first gas production valve and into riser
