摘要： A process for separating ethylbenzene and styrene by distillation is described. The process provides the advantages of a vapor compression/heat pump system, and is designed in such a manner that the energy applied is optimally utilized. The head pressure of the distillation column (1) is controlled in a simple manner, whereby a surprisingly stable column is achieved.

摘要： Process for recovering highly pure aromatic substances from mixtures of hydrocarbons which contain in addition to the aromatic substances, large amounts of non-aromatic substances by liquid-liquid extraction in combination with an after arranged extractive distillation whereby the liquid-liquid extraction of the starting hydrocarbon mixture is carried out under such conditions that the resulting extract contains substantially the total amount of the aromatic substances and a portion of the non-aromatic substances, introducing this extract into an after arranged extractive distillation for further separating said extract whereby the sump product (extract phase) formed is drawn off and introduced into an after arranged distillation column where it is separated into an aromatic and a solvent fraction, while the head product of the extractive distillation (raffinate phase) is reintroduced into the bottom of the extractor for liquid-liquid extraction thereof, wherein there is used in both of the extracting stages, as selective solvent, morpholine and/or N-substituted morpholine in admixture with water whereby the water content of the solvent for the liquid-liquid extraction amounts to between 2-15 weight percent and for the extractive distillation amounts to between 0 and 8 weight percent.

摘要： A process for the purification of pressurized gases, such as those emanating from the partial gasification resp. combustion of fuel, which gases contain Ni(CO).sub.4, which comprises contacting said Ni(O).sub.4 containing gas with a solvent at a temperature of from -60 to 0.degree. C., thereby forming a solution containing the gases and dissolved Ni(CO).sub.4, and thereafter heating said solution at a temperature of from 70 to 250.degree. C. for at least 0.25 hour at a pressure higher than the vapor pressure of said solvent, thereby precipitating and thereafter recovering nickel compound and releasing a purified solvent.
