Definitions
- the present invention relates to a phase separator for liquefied gas circulation systems.
- a particular object of the invention is to make it possible in circulation systems for conveying liquefied gases at very low temperatures to remove any quantities of gas which are gasified during transfer from place to place and to the points of utilization with a minimum pressure loss while at the same time preventing heating of the liquefied gas considered.
- This invention relates to a phase separator for a liquetied gas circulation system
- a phase separator for a liquetied gas circulation system comprising a separating chamber which is provided at the bottom portion thereof with a conduit for the admission of liquid and a conduit for the discharge of liquid and at the top portion thereof with gas-removing means fitted with a shutting-01f device, and means for controlling said gas-removing means in dependence on the depth of liquid within the separating chamber
- said control means comprise a manometric capsule consisting of a first chamber connected to the bottom portion of the separating chamber by means of a pipe in which the liquefied gas vaporizes and a second chamber connected to the top portion of the separating chamber, said two chambers being separated from each other by a deformable diaphragm.
- phase separator which is designed to be placed between two sections of a vacuum insulation pipe of the type usually employed for the purpose of conveying liquefied gases at very low temperature as has been described in particular in French Patent No. 1,322,181 of Jan. 23, 1962 in respect of Pipe-line for conveying liquefied gas.
- FIG. 1 of the accompanying drawings represents a diagrammatic view in vertical cross-section of the apparatus according to the invention.
- the separator described consists of a vertically-disposed separating chamber 1 of cylindrical shape, at the bottom portion of which is provided a conduit 2 for the admission of the liquid-gas mixture and a conduit 3 for the discharge of liquid phase, which is located diametrically opposite to said admission conduit and at the top portion of which is provided an opening 4 for the removal of the gaseous phase.
- a plane vertical partition wall 5 which is interposed between the inlet conduit 2 and outlet conduit 3 facilitates the separation of the two phases.
- the separating chamber 1 is arranged coaxially in the interior of a vessel 6 which is also cylindrical and which is provided with lateral extensions 7 and 8 around the conduits 2 and 3.
- the admission conduit 2 together with its outer sleeve which is formed by the extension 7 of the separating chamber has a shape which is identical with that of one female extremity of the pipe-line sections in which the separator is intended to be placed.
- the conduit 3 and the extension 8 of the outer vessel constitute a male extremity
- the inlet and ice outlet conduits 2 and 3 are fitted with contraction bellows 9 and 10 respectively, in the same manner as the pipe-lines for conveying liquefied gas. 7
- a valve 11 serves to create a vacuum within the space which is formed between the separating chamber and the outer vessel 6.
- the vacuum thus created can if necessary be maintained by means of a mass 12 of activated carbon which is contained in a perforated basket 13.
- the separating chamber 1 is provided on the external face thereof with a glossy multi-layer coating 14 which is intended to reflect thermal radiation.
- the relative centering of the two vessels or chambers is ensured by means of a log 15 which is integral with the separating chamber 1 and which is adapted to penetrate into a cup 16 forming part of the outer vessel 6.
- the lug 15 and the cup 16 are not usually in contact with each other when the apparatus is in operation.
- the separating chamber 1 is put into communication at the top portion thereof by means of the opening 4 and the conduits 17 and 18 with a differential pressure valve 19.
- Said valve is a manometric capsule which is divided into two chambers 22 and 23 by a flexible diaphragm 21.
- the conduit 18 and the discharge conduit 24 open into the bottom chamber 23.
- Said discharge conduit can be shut 01f by means of a disc valve 25 which is rigidly fixed to the diaphragm.
- the top chamber 23 communicates with the lower extremity of the separating chamber 1 via a pipe 26 of small cross-sectional area.
- the valve is fitted with a calibrating device 27 which establishes the valve-closing pressure.
- said pipe is designed in the shape of a siphon and is surrounded by a copper heating sheath 28 in the vicinity of the outer vessel wall.
- the length of the pipe 26 is sufiicient to ensure that the heat transfer between the cold wall'of the separating chamber 1 and the hot wall of the outer vessel 6 is low in value.
- the conduit 17 for the removal of the gaseous phase which is located within the vacuum space between the separating chamber 1 and the outer vessel 6.
- the conduit 17 additionally has a coil-shaped section which is located between the vessel 6 and the valve 19 and the purpose of which is to heat the gas to a sufficient extent to prevent any condensation at the level of the valve 19.
- a safety valve 30 which is fitted in the conduit 17 ensures the safety of the apparatus in the event of abrupt accidental heating of the liquefied gas which is being processed.
- the apparatus operates as follows: the liquid-gas emulsion which is admitted through the conduit 2 is separated into two phases within the separating chamber 1.
- the liquid phase flows through the conduit 3 whilst the gaseous phase escapes through the conduit 17.
- the level of liquid within the separating chamber 1 is maintained between two limits by the valve 19.
- the force which is exerted on the diaphragm 21 in the direction of closure of the valve is in fact produced by the hydrostatic pressure which is exerted by the head of liquid phase contained in the apparatus.
- the separator in accordance with the invention accordingly permits the possibility of effecting the separation of the gaseous phase formed within a liquefied gas pipeline under excellent conditions of thermal insulation and with a minimum pressure loss.
- Phase separator for liquified gas circulation systems comprising a separating chamber, a conduit at the bottom portion of said separating chamber for the admission of liquid, a conduit for the discharge of liquid for said separating chamber, a manometric capsule, a first chamber for said capsule, a pipe in which the liquified gas vaporizes connecting said first chamber to the bottom portion of said separating chamber, a second chamber for said capsule, a gas removing conduit connecting said second chamber to the top portion of said separating chamber, a gas discharge conduit from said second chamber, a deformable diaphragm separating said two chambers and a valve for discharging gas from said second chamber cooperating with said discharge conduit and rigidly fixed to said deformable diaphragm.
- Phase separator in accordance with claim 1, wherein a vacuum enclosure provides thermal insulation of the separating chamber.
