摘要： A process for the separation of oxygenated compounds, containing mainly methanol and possibly a minor amount of water and/or dimethyl ether, from a mixture of hydrocarbons containing 3 to 8 carbon atoms containing said oxygenated compounds. The mixture is distilled in a distillation zone (D). A gaseous distillate (line 2) is taken overhead which contains methanol, possibly water, possibly dimethyl ether, and hydrocarbons. The gaseous distillate is separated in a separator (B) and at least one organic liquid phase is recovered (line 6) and sent as a reflux to the head of distillation zone D. An aqueous liquid phase (line 5) may possibly be recovered, also a gaseous phase (line 4). A phase (line 8) is extracted as a side stream from the distillation zone and sent to a permeation zone (PV) comprising at least one membrane which is selectively permeable to methanol; a permeation step is carried out on said phase. At least one methanol-enriched permeate (line 14) is recovered downstream of the permeation zone, preferably as a vapor, and at least one residue (line 11) is recovered upstream which is optionally recycled to the distillation zone. The purified hydrocarbon mixture is extracted (line 16) from the bottom of the distillation column.

摘要： The present invention relates to a process for regenerating an at least partly reduced catalytic redox solution. The solution includes at least one polyvalent metal chelated by a chelating agent and is circulated in at least one regeneration zone while an oxygen-containing gas is injected into the regeneration zone. The process includes measuring a concentration of oxygen dissolved in a regeneration zone effluent. The process also includes adjusting a flow rate of the at least partly reduce catalytic redox solution entering the at least one regeneration zone and/or an oxygen-containing gas entering the regeneration zone in response to a measured concentration of oxygen, until a concentration of oxygen in the regeneration zone effluent is less than 20% of an amount of oxygen dissolved in water saturated with oxygen. Thus, degradation of the chelating agent in the catalytic redox solution is minimized.

At least a stream F1 comprising solvent, catalyst and sulfur and substantially free of the by-products and a stream F2 mostly comprising the by-products are recovered.

摘要： A process for separating a mixture containing mainly ethyl tertio-butyl ether (ETBE), ethanol and C.sub.4 hydrocarbons includes introducing the mixture to be separated into a debutanizer from which the C.sub.4 hydrocarbons are recovered overhead with a fraction of the ethanol, and purified ETBE is recovered as a bottom product; a side stream of an ethanol-rich phase is extracted and sent to a permeation zone in which the dense film of the membrane is constituted by a N,N-dimethylaminoethyl methacrylate polymer (DMAEMA) or a copolymer of DMAEMA with N-vinylcaprolactam (NVCL) and/or with N-vinyl pyrrolidone (NVP); the ethanol-depleted retentate from this permeation zone is returned to the debutanizer and the permeate contains mainly separated ethanol.The process can be integrated into an ETBE production process, in which the ethanol separated during the permeation step is recycled to the etherification reactor. The debutanizer may be replaced by a catalytic distillation column.

摘要： Process and device for regeneration of a used absorbent from a desulfurization zone or from the desulfurization of a gas containing sulfur oxides, comprising regeneration simultaneously with filtering of the absorbent, in a reducing atmosphere, wherein partial combustion of a regeneration gas is also carried out upstream from regeneration, the products of the partial combustion being mixed with the used absorbent prior to the regeneration-filtration stage. The absorbent may be, e.g., solid absorbents based on magnesium oxide. The regeneration gas may be hydrogen sulfide and/or a hydrocarbon. For example, H2S can be partially combusted and the products of the partial combustion, including H2S, H2, SO2 and sulfur, mixed with the used absorbent prior to the regeneration-filtration stage.
