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.

A submersible compressing apparatus comprising: This is a preferred method for control. Blow case design and control vs liquid handling capacity Blow case design and control vs liquid handling capacity We are using the horizontal blowcase system for liquid handling at suction compressor.
Method and system for offshore production of liquefied natural gas. Connected to the second opening of the compressor tank is a liquid conduit.
Sub-sea blow case compressor – ConocoPhillips Company
An apparatus of claim 4 further comprising an inlet valve connected to said evacuation conduit. Red Flag This Post Please let us know here why this post is inappropriate. A single acting compressor cycle, using only compressor tank 38is illustrated.
Compressor differs from compressor 70 shown in FIGS. It is qnd best practice that starting the intake process on a compressor tank immediately on stopping the intake process on another operaton tank allows pump 56 to operate continuously and not to be stopped or started during the cycling.

It’s easy to join and it’s free. The valves on all the conduits to the first compressor tank 38 are closed.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. If the compressor 90 is placed in position with both tanks empty, then by opening first inlet valve 50 one of the tanks may be filled with water to the desired level. Sub-sea production separators, i.
An apparatus of claim 5 further comprising an exhaust valve connected to blowcaes return conduit. Another potential function of exhaust valve 98 is to facilitate the reclaiming of any condensate that may be produced in the compressor system.
First opening 40 is connected to production conduit Connected to the first tank valve is an evacuation conduit. This is done by opening valve 52 and starting pump Compressor system in a subsea station for transporting a well stream. A first production conduit is attached to the anc opening of the first compressor tank. First gas production valve 46 remains closed and first gas valve 36 is opened.
Production gas conduit desitn connected to third gas valve and a third gas production valve A first production gas valve 46 is also connected to the first production gas conduit The sequencing of the actuated valves can be dependent only on the differential pressure across the valve without regard to any other measurements.
Compressor system and method of operation. A submersible compressing apparatus of claim 2 further comprising a first liquid level imlroved connected to said first compressor tank, and a second liquid level detector connected to said second compressor tank. Other valving and piping arrangements may be utilized. Submersible compressor 70 is comprised of two tank units.
A submersible compressing apparatus bkowcase claim 15 further comprising: 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.
This embodiment has a first compressor tank with a gas inlet opening and a gas exit openinga liquid inlet and a liquid exhaust opening One of the compressor tanks can be filled with water or other incompressible liquid at the surface.
Now that one of the tanks is filled the compressing mode is achieved by repeatedly transferring water from one compressor tank to the other compressor tank. While we have illustrated and described preferred embodiments of our invention, it is to be understood that these are capable of variations and modifications and we therefore do not wish to be limited to precise details set forth, but avail ourselves of changes and alterations as fall within the preview of the following claims.
Sub-sea blow case compressor. A submersible compressing apparatus of claim 4 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.
