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.

Improved Blowcase Operation and Design – Technische Informationsbibliothek (TIB)

Blow case design and control vs liquid handling capacity Get bigger valves trim. At the surface 18 of the sea is platform Feb 25, OK. This sequencing is illustrated in the table presented in FIG. The problem which we’re facing is it take so long time to dump the liquid out.

Search Expert Search Quick Search. Once one of the tanks 38 or 72 is opetation with the desired amount of water, first inlet valve 50 is closed.

Sub-sea blow case compressor – ConocoPhillips Company

Production conduit is connected to first gas valve 36 opposite the gas conduit Engineering Index Backfile For further questions please contact our TIB customer service.

In contrast to the open system of FIGS. This is done by opening valve 52 and starting pump Download Now White Paper: Nonroutine In this chapter we will learn about product design, which is the process of deciding on the unique characteristics and features of the companys product. The present invention relates to compressor apparatus for gas production from underwater wells.


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. Thereafter, the compressor 90 can be submerged and installed.

The compressing apparatus includes a first compressor tank 38 which has a first opening 40 and a second opening The valves on all the conduits to the first compressor tank 38 are closed.

Alternatively, return conduits and valves can be provided such that there is a closed system in which water or other incompressible liquid is pumped from one of the compressor tanks to the other compressor tank so as to provide a closed system in which the fluid is repeatedly transferred from one tank to the other.

The rate at which a tank is flooded and the rate at which water is pumped from it are proportioned preferably such that a nearly continuous intake of gas to the compressor apparatus can be achieved. Compressor differs from compressor 70 shown in FIGS. Limit the search to the library catalogue. Method and a system for separating and transporting gas and liquid.

Use of at least two compressor tanks is ane because production into the compressing apparatus can be dfsign continuous than in the blowwcase compressor tank configuration which operates in an interruptible fashion.

Method and apparatus for well bore construction. The second opening 76 is connected to second liquid conduit In one embodiment the invention relates to a compressor system suitable for use underwater. A first production conduit is attached to the first opening of the first compressor tank. A first production gas valve 46 is also connected to the first production gas conduit The compressor tanks of the present invention are preferably made of high iperation material such as steel, titanium and stainless steel.


A submersible compressing apparatus of claim 18 wherein said n compressor tanks blowcqse 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.

The return conduit 92 is connected to first return valve 94 and second return valve 96 and to the output end of pump Also it may be desirable to treat the surface of certain parts of the compressor with corrosion resistant layers.

When a desired amount of water has entered the compressor tank the inlet valve is closed and the process is repeated.

Connected to the second opening is the first liquid conduit which has connected to it a first inlet valve and a first tank valve. Underwater station for pumping a well flow. Red Flag This Post Please let us know here why this post is inappropriate.


Oct 30, A blowcase is a pressure vessel that collects fluid at low pressure, then upon fillage is pressurized with high pressure gas, causing the collected fluid to dispel into a medium pressure system. A single acting sequence is shown in FIG. As a starting configuration for discussion kmproved will be assumed that compressor tank 38 is empty.
