Process for eliminating the evaporation of a liquefied natural gas stream during the transfer thereof into a storage facility, comprising the following steps:

Method and apparatus to avoid LNG flash when expanding to the LNG storage facility

A process for the purification of a gas rich in hydrocarbons and comprising at least 10 ppm by volume of hydrocarbons having at least six carbon atoms nitrogen.

Method for purifying a gas rich in hydrocarbons

A method for producing liquefied natural gas and a stream of liquid nitrogen including step a): producing gaseous nitrogen in an air separation unit; step b): liquefying a stream of natural gas in a natural gas liquefaction unit including a main heat exchanger and a system for producing cold; step c): liquefying the nitrogen stream resulting from step a) in the main exchanger of the natural gas liquefaction unit in parallel with the liquefied natural gas in step b); wherein all the cold necessary for liquefying the stream of nitrogen and for liquefying the natural gas is supplied by the system for producing cold of the natural gas liquefaction unit.

Method for liquefying natural gas and nitrogen

The invention relates to a method for treating a mixture in order to separate carbon dioxide and hydrogen from said mixture, in which: i) the mixture is cooled and partially condensed and a first liquid is separated from the rest of the mixture in a first phase separator; ii) a gas from or derived from a gas from the first phase separator is treated in a hydrogen pressure swing adsorption module in order to produce a hydrogen-rich gas and a hydrogen-depleted residual gas; and iii) said hydrogen-depleted residual gas or a gas derived from said depleted gas is cooled and partially condensed and a second liquid is separated from the remaining gas in a second phase separator, separate from the first phase separator, wherein the first and/or second liquid being rich in carbon dioxide. The invention also relates to an installation for implementing such a method.

Treatment method for separating carbon dioxide and hydrogen from a mixture

In a process for the production of carbon dioxide and hydrogen from a gas flow comprising at least hydrogen, at least one sulfur-comprising component and carbon dioxide originating from a Claus unit fed with a gas comprising at least 50 mol % of oxygen, the gas flow is compressed and dried in order to produce a compressed and dried gas flow and the compressed and dried gas flow is separated at a subambient temperature in order to produce at least a fluid enriched in carbon dioxide with respect to the compressed and dried gas flow and at least a fluid enriched in hydrogen with respect to the compressed and dried gas flow.

Method and apparatus for producing carbon dioxide and hydrogen

The invention relates to a method for treating a hydrocarbon feed gas stream containing COand HS to recover a purified COgas stream (vii), comprising: a. Separating said feed gas stream into a sweetened gas stream (i), and an acid gas stream (ii); b. Introducing stream (ii) into a Claus unit wherein an oxygen-rich stream is used as a combustive agent in the Claus furnace, thereby recovering a liquid stream of elemental sulfur (iii) and a tail gas stream (iv); c. Introducing the stream (iv) into a Tail Gas Treatment Unit (TGTU) thereby separating said tail gas stream into a COenriched gas stream (v), and a stream enriched in sulfur compounds (vi); d. Compressing stream (v) exiting the TGTU; e. Passing the compressed COenriched gas through a COpurification unit thereby recovering a purified COgas stream (vii), and the device for carrying out said method.

[object Object]

The invention relates to a unit for the purification of a gas flow comprising CO and at least 45% CO2 and a method of operating said unit. In one embodiment, said unit contains a first compressor, a heat exchanger configured to cool the compressed gas flow, a separation chamber configured to separate head gas produced in the heat exchanger, a heater disposed on the line of the head gas originating from the separation chamber, a catalytic oxidation unit for oxidizing the compressed CO in the gas flow originating from the heater, and turbines placed downstream of the catalytic oxidation unit.
