Publication number: 20120205589Abstract: The object of the invention is a method for producing naphthenic process oils that have a high content of naphthenic carbon atoms of 20-60 wt % and a low content of polycyclic aromatics of less than 3 wt %, determined in accordance with IP 346, by the hydrogenation of a process oil educt that has a high content of polycyclic aromatics. The method in accordance with the invention enables secondary extracts, such as are formed in the production of label-free process oils, even in a mixture with primary extracts, to be utilized in an economically meaningful way. The resulting process oils are likewise label-free, so that the use of PCA-containing process oils can be reduced and less of these substances will get into the environment. Through this the environment and in particular health are less stressed. In addition, the starting substances in this way can lead to a different use and no longer have to be added to heating oil. By avoiding heating oil, CO2 emissions are also reduced.Type: ApplicationFiled: October 14, 2010Publication date: August 16, 2012Inventor: Nils Hansen

Publication number: 20120061614Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios >0.5:1 (approaching 1:1) may be achieved.Type: ApplicationFiled: September 9, 2011Publication date: March 15, 2012Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: David C.
