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.

Sub-sea blow case compressor – ConocoPhillips Company

Resources Digital Transformation may dwsign defined in a number of different ways by analysts or enterprise software vendors. The pump is started and water is pumped from the compressor tank.

A submersible compressing apparatus of claim 5 wherein said first production gas valve, first gas valve, second production gas valve, and second gas valve are check valves.

Further, in the closed circuit embodiment neither the first inlet valve 50 nor the exhaust valve 98 is required. The process is reversed in a similar fashion as described above to produce a second compressing cycle.

Production Equipment

A blowcasf compressing apparatus of claim 15 further comprising: Home Forums Petroleum Engineers Activities Petroleum production engineering Forum Blow case design and control vs liquid handling capacity thread Forum. How can we minimize this time? Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

My question are, 1. Subsea well production facility. Method and apparatus for disposing of water at gas wells. Thus, while one vessel is performing the intake process, opreation other vessel is performing the compression process. The pump withdraws water from the second compressor tank through second exhaust valve which causes gas to be drawn into the second compressor tank from the liquid gas separator 22 through second gas valve The opposite side of second exhaust valve is connected to evacuation conduit which is connected to pump In this situation, the sequencing system would open the valve when the pressure measured across the valve in the desired direction of flow is positive, and would close the valve when the pressure measured across the valve in the desired direction of flow is negative.


A submersible compressing apparatus of claim 4 further comprising a first liquid vlowcase detector connected to said first compressor tank, and a second desiyn level detector connected to said second compressor tank.

Referring now to FIG. Second return valve 96 is open and the water is pumped into the second compressor tank 72thereby expelling the gas from second compressor tank 72 through open second production gas valve 82 and into the gas riser Red Flag This Post Please let us know here why this post is inappropriate. Once a well is placed in production the raw material flowing from the well may be transported to the surface through a tubing string or riser, or may be transported to the shore through a sub-sea pipeline.

For further questions please contact our TIB customer service. Alternatively, either valves 52 or 88 can be opened allowing water to flow into selected tanks under the force of the hydrostatic head.

Dwsign inlet valve to the compressor tank is opened and water from the environment is allowed to flood the tank.

It is believed that continuous operation of the pump prevents or minimizes wear and tear caused by starting and stopping the pump and would increase pump life. We will also learn about process selection, which is the development of the process necessary to produce the designed product. Pump is started. I would be grateful, if experts can guide me in the design The standard design provides extra aftercooling, in part to support glycol dehydrator operation.

agree, remarkable Improved blowcase operation and design pdf

Now that iperation of the tanks is filled the compressing mode is achieved by repeatedly transferring water from one compressor tank to the other compressor tank. A single acting compressor cycle, using only compressor tank 38is illustrated. Each unit has a compressor tank; with conduit means for passage of gas into and out of each of the n compressor tanks; with conduit means for passage of liquid into and out of each of the n compressor tanks, valve means to control inlet and outlet of gas from each compressor tank, valve means for controlling the inlet and exit of liquid from each compressor tank; and a pump means for exhausting liquid into the ambient surrounding or to transfer liquid from one compressor tank to another.


With a single compressor tank, the compression process is started immediately after the intake process is stopped and vice versa. The exact arrangement of the conduits and valves is not important.

Liquid can then be pumped from one tank to the other. Do you have the program for calculation of the time for dump at difference value of drive gas pressure and liquid volume in the blowcase? Use of at least two compressor tanks is preferred because production into the compressing apparatus can be more continuous than in the single compressor tank configuration which operates in an interruptible fashion.

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 conduit Andd the level in the vessel performing the compression process reaches maximum, all the water valves for that vessel are closed and the vessel remains operafion a holding state with no gas or water entering or exiting until the intake process on the other vessel is stopped.
