Low Temperature Steam Stripping For Byproduct Polymer And Solvent Recovery From An Ethylene Oligomerization Process
US Patent:

International Classification:
C07C 7/00, B01D 3/38
US Classification:
585809, 585802, 208255, 208356, 208362
Abstract:
This disclosure relates generally to low temperature steam stripping methods for byproduct polymer and solvent separation from an ethylene oligomerization process. The methods disclosed have been found to separate byproduct polymer from solvent without fouling process equipment or causing other process problems. The byproduct polymer ends up as flowable solid particles in a water stream that may be easily discharged from the process, while solvent is recovered for recycle to the process. In embodiments of the invention, over 90 wt % of the solvent used is recovered and the discharged byproduct polymer is less than 20 wt % solvent.
Separation Of Olefin Vapor From Liquid Fraction To Reduce Fouling

International Classification:
B01D 11/00
US Classification:
210634
Abstract:
This invention is directed to methods of removing water and other condensable materials, as well as solids particles such as catalyst particles, from olefin product streams so as to reduce fouling in the liquid and vapor separation equipment. In order to reduce fouling or contamination in the condensing or quenching process, this invention includes adding a hydrocarbon to at least a portion of the condensed liquid fraction in an amount that effects separation of the liquid fraction into upper and lower fractions.

International Classification:
C07C 29/00, B01J 21/04, B01J 23/02
US Classification:
568897, 502340, 502342, 502344, 502346, 568895
Abstract:
This invention is directed to a process for making alcohol from syngas, and a process for making olefin, as well as polyolefin, from the alcohol. The syngas is converted to a mixed alcohol stream using a catalyst comprising at least one oxide component. Upon contacting the catalyst with a desired syngas composition, a preferred mixed alcohol product is formed. Preferably, the syngas composition has a stoichiometric molar ratio of less than 2.
Converting Methanol And Ethanol To Light Olefins
US Patent:

Filed:
Mar 8, 2005
Appl. No.:
11/075286

International Classification:
C07C 1/00
US Classification:
585639000
Abstract:
The present invention provides processes for producing light olefins from a feedstock comprising methanol and ethanol. The ethanol is converted to ethylene and water over a dehydration catalyst, while the methanol is converted to light olefins and water over a molecular sieve catalyst. These conversion steps may occur in two separate reactors operating in series or in parallel, or in a single reactor containing a mixture of dehydration catalyst and molecular sieve catalyst.

International Classification:
C07C 1/20
US Classification:
585640, 585329, 585501, 585638, 585639
Abstract:
This invention is directed to a process for producing olefin product from an oxygenate feed that includes dimethyl ether (DME). The process uses an olefin forming catalyst that contains a porous crystalline material, preferably a porous crystalline aluminosilicate molecular sieve material. The process produces high quantities of light olefin (i. e. , ethylene, propylene, and mixtures thereof).

Abstract:
A method of producing synthesis gas for methanol synthesis that comprises the steps of: (a) obtaining a hydrogen stream that has greater than 5 mol % methane from an external process; (b) feeding into a reforming reactor: (i) a feed gas that comprises methane, (ii) water in a specified amount, (iii) oxygen in a specified amount, and (iv) the hydrogen stream in a specified amount; (c) reacting the feed gas, water, oxygen and the hydrogen stream in the reactor; and (d) withdrawing from the reactor the synthesis gas that is at a specific temperature, has less than 3 mol % methane, and has a stoichiometric number of from 1. 9 to 2. 3.
