    摘要： A system for liquefying production gas from a gas source containing a fluid having C1-C12 entrained gases includes a first phase separator for separating the C1-C12 gases from the fluid from the gas source. The first phase separator has an inlet in fluid communication with the gas source, a gas outlet and at least one alternative outlet. A first cryogenic liquefaction vessel has an inlet and an outlet. The inlet is in fluid communication with the gas outlet of the first phase separator. The first cryogenic liquefaction vessel cools the C1-C12 gases to liquefy the C3-C12 petroleum gases. A second phase separator is provided for separating the C3-C12 liquefied gases from the C1-C2 gases. The second phase separator has an inlet, a liquid outlet and a gas outlet. The inlet is in fluid communication with the outlet of the first cryogenic liquefaction vessel. At least one storage vessel is provided in fluid communication with the liquid outlet of the second phase separator for collection of the liquefied C3-C12 petroleum gases.

    摘要： A system and a process are provided for cooling a natural gas feed to an aluminum heat exchanger to protect it from mercury damage and increase productivity. A multi-stage vaporization system is employed wherein the last stage or lowest pressure heat exchanger is provided with a propane ejector. This allows the last stage heat exchanger to operate at a very low pressure without unduly reducing the pressure within other parts of the system. The last stage heat exchanger is accordingly able to sufficiently reduce the temperature of the feed to the aluminum heat exchanger to protect against mercury contamination. In addition, the decreased heat transfer load of the aluminum heat exchanger leads to an increase in the LNG production rate.

    摘要： A device for pressurizing a plate bundle which is arranged in a leakproof vessel (2) and comprises a stack of plates which are parallel to one another to form a first circulation circuit for a first fluid under pressure and a second circulation circuit for a second fluid under pressure. The device includes a first conduit (15) for connecting the vessel (2) to the delivery (10) of the first fluid continuously feeding the vessel (2), a second conduit (16) for connecting the vessel (2) to the delivery (12) of the second fluid feeding the vessel (2) in the event of stoppage of the delivery of the first fluid, and controls (20) for feeding of the vessel (2) with the second fluid.
