20130172627 | PROCESS FOR PREPARING LOWER OLEFINS - The invention is a process for preparing lower olefins comprising: a) steam cracking a paraffinic feedstock to obtain a cracker effluent comprising olefins and saturated and unsaturated C4 hydrocarbons; b) contacting an oxygenate feedstock with a molecular sieve-comprising catalyst, at a temperature in the range of from 350 to 1000° C. to obtain an oxygenate conversion effluent comprising olefins and saturated and unsaturated C4 hydrocarbons; c) subjecting the cracker effluent and the oxygenate conversion effluent to one or more separation steps such that an olefin product stream comprising ethylene and/or propylene, and a stream comprising saturated and unsaturated C4 hydrocarbons are obtained; and d) subjecting part of the stream comprising C4 hydrocarbons from both the cracker effluent and the oxygenate conversion effluent to extractive distillation to obtain a stream enriched in unsaturated C4 hydrocarbons and a stream enriched in saturated C4 hydrocarbons. | 07-04-2013 |
20130184498 | PROCESS FOR THE PRODUCTION OF DIMETHYL ETHER - A process for the production of dimethyl ether from a methanol reactor effluent is disclosed. The process may include: contacting an aqueous extractant comprising water and an effluent from a methanol synthesis reactor comprising methanol and one or more of methane, water, carbon monoxide, carbon dioxide, hydrogen, and nitrogen. At least a portion of the methanol partitions into the aqueous extractant; recovering an extract fraction comprising the aqueous extractant and methanol. The extract fraction is fed to a catalytic distillation reactor system for concurrently: contacting the methanol with catalyst in a reaction zone thereby catalytically reacting at least a portion of the methanol to form dimethyl ether and water; and fractionating the resulting dimethyl ether and the water to recover a first overheads fraction comprising dimethyl ether and a first bottoms fraction comprising water. | 07-18-2013 |
