US Patent:

6706093, Mar 16, 2004

Filed:

May 2, 2001

Appl. No.:

09/847126

Inventors:

Abraham Benderly - Houston TX
Michael Stanley DeCourcy - Houston TX
Ronald Eugene Myers - Houston TX

Assignee:

Rohm and Haas Company - Philadelphia PA

International Classification:

B01D 5314

US Classification:

95232, 423237

Abstract:

A method which reduces iron contamination of a system which receives ammonia from an ammonia recovery process by one or more of the following techniques: a) Physically separating iron oxide, iron containing colloidal particles, and liquid droplets from the gas stream; b) Preventing AC from depositing on piping via elimination of condensation, thereby preventing corrosion of the piping; or c) Installing piping and equipment that is not susceptible to corrosive attack by AC, thereby eliminating the source of iron contamination.

International Classification:

C01C 1/12
B01J 19/02

US Classification:

423238, 422240, 423352

Abstract:

An improved process for ammonia recovery is provided for the recovery of substantially pure ammonia for use in industrial processes. In this improved method, specific raw materials and/or specific materials of construction are used. Overall efficiency and operational cost savings are increased as a result of the process of the present invention.

Appl. No.:

09/847345

Inventors:

Abraham Benderly - Houston TX, US
Michael DeCourcy - Houston TX, US
Ronald Myers - Houston TX, US

International Classification:

C01C003/00
C01C001/04

US Classification:

423/238000

Abstract:

The present invention provides a novel process of recovering unreacted ammonia from a reactor effluent. This novel process includes at least the following steps: (1) quenching a reactor effluent containing ammonia with a first aqueous ammonium phosphate quench solution, wherein the pH of the solution is less than about 3.5, thereby absorbing ammonia to form a second aqueous ammonium phosphate solution richer in ammonium (NH) ions than the first solution but substantially free of dissolved CO, (2) heating the second solution to an elevated temperature to reduce the amount of ammonium ions present to substantially the same level present in the first solution and thereby generate a vaporous stream containing ammonia, (3) recycling said vaporous stream containing ammonia to a reaction zone in a manner that minimizes the contamination of the reaction zone.

International Classification:

B01J008/02
B01J035/02

US Classification:

422/211000

Abstract:

A lab-scale reactor unit comprises a body of thermal insulating material, a reaction chamber formed within the body of thermal insulating material, a pressure containment vessel disposed about the body of thermal insulating material, the pressure containment vessel having an inlet communicating with the reaction chamber, the pressure containment vessel having an outlet communicating with the reaction chamber and a quench cooler operatively connected to the outlet of the pressure containment vessel.
