Filed:

Feb 3, 2011

Appl. No.:

13/020266

Inventors:

Christopher J. LaFrancois - Bartlesville OK, US
James F. Stewart - Bartlesville OK, US
Gregory C. Allred - Bartlesville OK, US
Marlon Ash - Nanwalek AK, US

Assignee:

Phillips 66 Company - Houston TX

International Classification:

G01N 33/28

US Classification:

356 70

Abstract:

An oil in water analyzer for measuring the concentration of hydrocarbons in an effluent stream. The oil in water analyzer has a valve system for acquiring a sample from an effluent stream. An extraction device is used for mixing a known volume of a solvent and the sample to produce a hydrocarbon/solvent mixture. A second valve is used for transporting the hydrocarbon/solvent mixture to a spectroscopic cell. It is at the spectroscopic cell where the concentration of hydrocarbons in the hydrocarbon/solvent mixture is evaluated.

International Classification:

B01J 20/34

US Classification:

502 41, 502 38, 502 34

Abstract:

A method for regenerating desulfurization sorbents that minimizes the in situ formation of one or more silicates. It has been discovered that regenerating sulfur-laden sorbent particles in a carbon oxide-rich environment unexpectedly reduces the in situ silicate formation rate, as compared to similar sorbents regenerated using conventional methods.
