Appl. No.:

11/533983

Inventors:

John Tomlinson - Prairieville LA, US
Roy Kennedy - Prairieville LA, US
Jose M. Sosa - Deer Park TX, US

Assignee:

Fina Technology, Inc. - Houston TX

International Classification:

B01D 19/00

US Classification:

159 21, 528501, 528502 R, 96200, 96203, 159 431, 159 274

Abstract:

A vessel header comprising a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube. A method of increasing the throughput of a polymerization reaction comprising conducting the polymerization reaction in a reaction vessel comprising a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube wherein the polymerization reaction displays an increase in throughput of 10% and a decrease in volatiles of from 5% to 10% when compared to a polymerization reaction carried out in a reaction vessel lacking a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube.

Appl. No.:

13/075211

Inventors:

John Tomlinson - Prairieville LA, US

Assignee:

Fina Technology, Inc. - Houston TX

International Classification:

C08F 2/01

US Classification:

525 53

Abstract:

A process for producing a high impact polystyrene having a high swell index including feeding at least one vinyl aromatic monomer and at least one elastomer to at least one polymerization reactor to form a reaction mixture, polymerizing the reaction mixture, combining a chain transfer agent to the reaction mixture leaving the at least one polymerization reactor to form a combined mixture, sending the combined mixture to a devolatilization zone and obtaining a HIPS product having a high swell index.
