US Patent:

6508863, Jan 21, 2003

Filed:

Oct 11, 2001

Appl. No.:

09/975720

Inventors:

John W. Byrne - Edison NJ
William B. Dolan - Yardley PA
Kenneth F. Butwell - Newburgh NY

Assignee:

Engelhard Corporation - Iselin NJ

International Classification:

B01D 5304

US Classification:

95143, 95235, 95902

Abstract:

A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent that selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream that is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include Y-type zeolites having a silica to alumina mole ratio of less than 15 and a reduced sodium content.

Appl. No.:

11/377840

William Dolan - Yardley PA, US

International Classification:

C01B 33/36

US Classification:

423716000

Abstract:

The effective pore diameter of ETS-4 can be controlled without thermal treatment by selecting various combinations of cations to exchange into ETS-4. The effect that any cation mixture has on the ETS-4 can be reduced to the weighted average of the effects of each cation present.

Filed:

Dec 27, 1993

Appl. No.:

8/173386

Inventors:

Lawrence T. Kass - White Plaines NY
William B. Dolan - Dobbs Ferry NY

Assignee:

UOP - Des Plaines IL

International Classification:

B01D 53047

US Classification:

95103

Abstract:

A pressure swing adsorption (PSA) process is provided for the size-selective separation of a feedstream into an adsorbate fraction employing a rapid blowdown step to induce a state of disequilibrium within an adsorbent bed and thereby increase the weight hourly space velocity of the process. The selective separation mechanism explored in the PSA process may also include equilibrium separation. The benefits include a reduced adsorbent bed size for new installations or increased feed rates for existing facilities. In one aspect of the invention the feedstream to be separated comprises iso and normal pentane.
