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.

Society of Petroleum Engineers. 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. A sub-sea submersible compressing apparatus having at least one compressor tank.
The harder I work, the luckier I seem. Method and system for offshore production of liquefied natural gas. The second manner of making the initial charge of water inproved to close both the first and second tank valves 52 and 88 and either one of the first or second blowcaze valves 94 and 96the other return valve is opened.
It being understood that the invention can also be employed in other water environments.
agree, remarkable Improved blowcase operation and design pdf
We are using the horizontal blowcase system for liquid handling at suction compressor. Then the first inlet valve 50that has an inlet 58 which is open to the sea, is opened. Compressor differs from compressor 70 shown in FIGS.
In the illustrated phase of the compressing in FIG. 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.
While the invention may be used in freshwater or seawater its greatest application will be found in offshore applications. Click Here to join Eng-Tips and talk with other members! The side of the second gas production valve 82 is connected to imoroved The opposite side of second exhaust valve is connected to evacuation conduit which is connected to pump Thereafter, the compressor 90 can be submerged and installed.
TECHNICAL FIELD
When the level in the vessel performing the compression process reaches maximum, all the water valves for that vessel are closed and the vessel remains in a holding state with no gas or water entering or exiting until the intake process on the other vessel is stopped.
The pump is started and water is pumped from the compressor tank. A submersible compressing apparatus of claim 18 wherein said n compressor tanks are free of a device to prevent disturbance of the surface of the liquid contained in the n compressor tanks by the gas flowing into and out of the ii compressor tanks.
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. 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 The Liquid Removal 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 a pump.

Gas valve 36 is then closed and first gas production valve 46 is opened. Production conduit is connected to first gas valve 36 opposite the gas conduit The arithmetic was all mass balances, I don’t think there was anything special. A second inlet valve is connected to the second liquid inlet conduit and a second exhaust valve is connected to the second liquid exit conduit Hi all, In one of our Projects, I have a task of sizing the blow case.
Closing the corresponding water valves 50528688 to stop the compression process or to stop the intake process in each vessel will satisfy criteria 3 and 4.

A double cycle is illustrated in FIG. Connected to gas inlet opening of the second compressor tank is second gas inlet conduitconnected to imprlved gas exit opening of the second compressor tank is second production gas conduit In this embodiment, the closed circuit compressor has a first inlet valve 50 which is connected to the evacuation conduit
