A method for treating a natural gas containing carbon dioxide using membrane modules which are assigned to a first treatment stage or a second treatment stage and are fluidically connected to a retentate mode or a permeate mode. When evolution in the operating conditions results in one of the processing levels requiring less membrane surface for gas processing and the other processing level requiring more membrane surface for gas processing, then the method allows for reassignment of needed membrane modules assigned from one processing level requiring less membrane surface to another processing level requiring more membrane surface.

Process for treating a natural gas containing carbon dioxide

The present invention relates to a method for the catalytic conversion in vapor phase of disulfide oil into methane and hydrogen sulfide, comprising the step of contacting disulfide oil, eventually in the presence of water, with a supported transition metal catalyst.

Catalytic conversion of DSO in presence of water

The present invention relates to a gas-redirecting device presenting an upper plane and a plurality of gas-redirecting tubes comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50% of the total area of the upper plane covered by the orthogonal projections. Also provided is a liquid-gas contacting column comprising a gas-redirecting device, a floating support comprising a liquid-gas contacting column, at least two packed beds and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed.

The invention relates to a method for the treatment of natural gas containing carbon dioxide, methane and paraffins. The method comprising: a step of extracting the paraffins from the natural gas in a paraffin-removal column, and a step of separating the carbon dioxide and the methane in a distillation column. The operation of the two columns being provided by means of the thermal coupling of said two columns using a thermal coupling heat exchanger.

Process for purifying gaseous mixtures containing acidic gases

The invention concerns a method for treating a hydrocarbon feed gas stream containing at least COand HS to recover a high quality purified COgas stream, comprising a. Separating said hydrocarbon feed gas stream into a sweetened hydrocarbon gas stream, and an acid gas stream; b. Introducing said gas stream into a Claus unit, c. Introducing the tail gas into a hydrogenation reactor and then into a quench contactor of the Tail Gas Treatment Unit (TGTU); d. Contacting said tail gas stream with a non-selective amine-based solvent into a non-selective acid gas absorption unit of the TGTU; e. Sending the off gas to an incinerator; f. Contacting said enriched gas stream (vii) with a selective HS-absorption solvent into a selective HS-absorption unit thereby recovering a highly purified COgas stream and a HS-enriched gas stream, as well as the device for carrying said method.

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.

The invention relates to a method for treating a hydrocarbon gas stream containing H2S and mercaptans, in which dialkyldisulfides are produced then removed by hydrogenation, as well as a device for carrying out said method.

Integrated process for dialkyldisulfides treatment

The disclosure relates to a process for treating a gas mixture containing carbon dioxide and hydrogen sulphide, including the following steps: deacidificating the gas mixture by bringing the gas mixture into contact with a first lean absorbent solution stream, delivering a deacidified gas mixture, and a first rich absorbent solution stream; regenerating the first rich absorbent solution stream, delivering the first lean absorbent solution stream and a sour gas stream; distillating the sour gas stream, delivering a first carbon-dioxide-rich stream and a hydrogen-sulphide-rich stream; purifying the first carbon-dioxide-rich stream by bringing the first carbon-dioxide-rich stream into contact with a second lean absorbent solution stream, delivering a second carbon-dioxide-rich stream and a second rich absorbent solution stream, the molar concentration of carbon dioxide in the second carbon-dioxide-rich stream being greater than the molar concentration of carbon dioxide in the first carbon-dioxide-rich stream. The disclosure also relates to an installation designed to implement this process.

Sour gas treatment process

A method for treating a gas mixture containing acid gases, including: contacting the gas mixture with an absorbing solution, to obtain a de-acidified gas mixture and an absorbing solution with acid gases. To regenerate the absorbing solution with acid gases, the absorbing solution is passed into a first regenerator at a first pressure, then the solution is passed into a second regenerator at a second pressure, and finally to a third regenerator at a third pressure, the third pressure being less than the second pressure which is less than the first pressure. The gases from the second and third regenerator are compressed and recycled to the first and second regenerator, respectively. Gases from the second and/or the third regenerator are drawn off to provide a gas mixture rich in hydrogen sulfide. Gases from the first regenerator are drawn off to provide a gas mixture rich in carbon dioxide.
