Patent application numberDescriptionPublished
20120085711PROCESS FOR THE OXIDATION OF WASTE ALKALI UNDER SUPERATMOSPHERIC PRESSURE - The invention relates to a process for the treatment of a used waste alkali, in which the used waste alkali is oxidized at a superatmospheric pressure in the range from 04-12-2012
20130197288PROCESS FOR THE CONVERSION OF SYNTHESIS GAS TO OLEFINS - The present invention relates to a process for converting a gas mixture comprising CO and H08-01-2013
20140343339METHOD FOR OBTAINING OLEFINS FROM FURNACE GASES OF STEEL WORKS - The invention relates to a method for processing furnace gas (11-20-2014
20150025292SEPARATION SEQUENCE FOR HYDROCARBONS FROM A GENTLE THERMAL CLEAVAGE - The invention describes a method for separating hydrocarbons in an installation for generating hydrocarbons from a hydrocarbon-containing charge by cleavage. The product gas of the cleavage, which contains gaseous hydrocarbons, is compressed, dried, and supplied as charge material into a separation stage (a front end C3/C4 separation). The front end C3/C4 separation comprises a C4 absorber and a depropanizer. A hydrocarbon fraction consisting of hydrocarbons having a maximum of 3 carbon atoms is obtained as a gaseous overhead product of the C4 absorber. A liquid hydrocarbon fraction consisting of hydrocarbons having at least 4 carbon atoms is obtained as a bottom product of the depropanizer. The front end C3/C4 separation comprises an additional process technological C2/C4 separation stage is arranged between the C4 absorber and the depropanizer.01-22-2015
20150044129METHOD FOR PROCESSING COKE OVEN GAS - The invention relates to a method for processing coke oven gas, said coke oven gas containing hydrogen, wherein the coke oven gas is at least partially integrated into a method for producing dimethyl ether in conjunction with a gas containing carbon monoxide and/or carbon dioxide, whereby a DME-containing product gas is formed. At the outset of the method for the formation of dimethyl ether, a ratio of hydrogen to carbon monoxide, weighted with the carbon dioxide concentration (formula (I)), of 0.9 to 1.1 is set, wherein the DME-containing product gas is integrated into a method for converting dimethyl ether to olefins, whereby an olefin-containing product gas is formed, and wherein olefins, in particular ethylene and/or propylene, is/are separated from the olefin-containing product gas by means of separating methods.02-12-2015

20150018582DIRECT DIMETHYL ETHER SYNTHESIS FROM SYNTHESIS GAS - The invention concerns processes for preparing dimethyl ether from synthesis gas, comprising a synthesis step, wherein synthesis gas comprising hydrogen and carbon monoxide is converted into dimethyl ether and carbon dioxide, and a separation step, wherein unconverted synthesis gas is separated from carbon dioxide, wherein unconverted synthesis gas is separated from carbon dioxide by a membrane.01-15-2015
20150018592DIRECT SYNTHESIS OF DME AT EQUILIBRIUM - The invention relates to a process for production of DME (01-15-2015
20150045456METHOD FOR PRODUCING DIMETHYL ETHER FROM METHANE - The invention relates to processes for production of dimethyl ether from methane or natural gas comprising: a dry-reforming step, wherein methane and carbon dioxide are converted into carbon monoxide and hydrogen, and a DME synthesis step, wherein the carbon monoxide and hydrogen formed in the dry-reforming step are converted into dimethyl ether, wherein the dry-reforming step and the synthesis step are carried out at identical pressures or at pressures, which do not differ more than 3 bar, preferably not more than 1 bar.02-12-2015
20150065770METHOD FOR SEPARATING OLEFINS WITH GENTLE CLEAVAGE - A process for producing olefins, in which a hydrocarbon-containing feed is fed into a cracking furnace where relatively long-chain hydrocarbons of the hydrocarbon-containing feed are cracked at least partly to form shorter-chain olefins, encompassing ethylene and propylene. Cracking gas (03-05-2015
