摘要:
The present invention relates to a process and to a plant for dehydrating a liquid or gaseous effluent, in which the following steps are carried out: the effluent is neutralized by at least one of the following caustic brines: caustic soda, caustic potash or mixtures thereof; the neutralized effluent is dehydrated over caustic soda or potash pellets; and the caustic brine resulting from the dehydration is collected and used in the neutralization step (2).
摘要:
The invention relates to a method for extracting sulphur compounds from an LPG- or petrol-type hydrocarbon fraction, by means of liquid-liquid extraction with a soda solution, using a pre-treatment unit (2) for pre-treating the feedstock to be treated, placed upstream of the extraction unit (4), in which the soda is introduced into the extraction column (4) in the form of two circuits operating in parallel.

The invention relates to a method for extracting sulphur compounds from an LPG- or petrol-type hydrocarbon fraction, by means of liquid-liquid extraction with a soda solution, using a pre-treatment unit (2) for pre-treating the feedstock to be treated, placed upstream of the soda-based extraction unit (4), said pre-treatment unit being formed by a first non-continuous pre-treatment reactor followed by a second piston-type continuous reactor operating in piston mode.
