A process for partial dehydration of a gas by contact with a solvent that can be regenerated by: a) A stage for absorption of HO by contact of the gas to be treated and regenerated solvent producing a dehydrated gas effluent and a liquid solvent effluent that is charged with HO and absorbed gas, b) A stage for cooling the solvent charged with HO at ambient temperature, c) A stage for separation by segregation during which liquid HO and the solvent are separated at ambient temperature, d) A stage in which the regenerated solvent that is obtained at the end of stage c) is heated, e) A stage in which the regenerated and heated solvent that is obtained at the end of stage d) is recycled to the absorption stage a).

The liquid hydrocarbon stream including COS is introduced via lineinto membrane contactor CM to be placed in contact, through membrane M, with the aqueous alkanolamine solution arriving via lineThe COS contained in the hydrocarbon stream is absorbed by the aqueous alkanolamine solution. The liquid hydrocarbons from which the COS has been removed are evacuated from CM via lineThe aqueous solution containing COS is sent via lineto zone R to be regenerated. The compounds released during regeneration, particularly COS and COS-derived products, are evacuated from zone R via lineThe regenerated aqueous alkanolamine solution is recycled via lineinto membrane contactor CM.

The gaseous effluent flowing in through lineis contacted in absorption zone ZA with the liquid absorbent solution flowing in through lineThe gaseous effluent depleted in acid compounds is discharged through lineThe absorbent solution laden with acid compounds is discharged through lineThe absorbent solution once laden with acid compounds comprises two phases: a first phase poor in acid compounds and a second phase rich in acid compounds. The two phases are separated in zone ZS. The first phase is recycled through linesandto absorption zone ZA. The second phase is fed through lineinto regeneration zone ZR. In zone ZR, the acid compounds are separated from the absorbent solution. The acid compounds are discharged through lineThe regenerated absorbent solution is recycled through linesandto zone ZA.

Method for modeling the flocculation conditions of hydrocarbon-containing fluids under pressure, related to a reference fluid. The asphaltenic properties are modeled from the results of an experimental study of a single asphaltenic reference fluid and by means of homothetic transformation laws. These reduced data allow to deal with asphaltenes flocculation in an industrial simulator working according to a simplified model. It is then possible to predict the amounts of asphaltenes that will flocculate in a reservoir or in a reactor during development, considering the variable pressure and composition conditions. Application: optimization of the development conditions of reservoirs or of an industrial reactor in which asphaltenic fluids undergo expansions.

Within the scope of a process using two absorption sections for treating a natural gas containing CO and/or H S, as well as mercaptans, COS and/or CS , the present invention aims to wash the gaseous hydrocarbons desorbed upon expansion of the solvent from the first absorption section with the solvent from the second absorption section.

The invention is a method for determining the Joule-Thomson coefficient of a fluid, expressing the temperature variation in relation to a pressure variation thereof. The fluid is injected at a determined injection temperature into a thin tube (,) (preferably a capillary tube in order to obtain a high pressure drop with reasonable flow rates) which contains a temperature detector (TC,) leading to a pressure drop for the fluid. The temperature variation of the fluid in relation to the injection temperature is measured by means of this temperature detector. The pressure drop undergone by the fluid in tube (,), due to the presence of this temperature detector, is also measured and the Joule-Thomson coefficient is calculated by combination of measurements of the pressure drop and of the temperature variation of the fluid. The method can be applied notably in the field of hydrocarbon production, more particularly hydrocarbons coming from high-pressure and high-temperature reservoirs and in gas lines.
