| 20120085711 | PROCESS 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 |
| 20130197288 | PROCESS FOR THE CONVERSION OF SYNTHESIS GAS TO OLEFINS - The present invention relates to a process for converting a gas mixture comprising CO and H | 08-01-2013 |
| 20140343339 | METHOD FOR OBTAINING OLEFINS FROM FURNACE GASES OF STEEL WORKS - The invention relates to a method for processing furnace gas ( | 11-20-2014 |
| 20150025292 | SEPARATION 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 |
| 20150044129 | METHOD 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 |
