US Patent:

54201942, May 30, 1995

Filed:

Feb 14, 1994

Appl. No.:

8/194677

Inventors:

Carl T. Rowe - Missouri City TX
Sherri L. Fisher - Sugar Land TX

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

C08L 3700

US Classification:

524549

Abstract:

A method for dispersing heavy hydrocarbons in an ethylene process water stripper tower, the method comprising the steps of: introducing an effective amount of a dispersant into the ethylene water stripper, the dispersant comprising a copolymer of an. alpha. -olefin having from about 10 to about 36 carbon atoms and a maleic anhydride, wherein the rate ratio of the. alpha. -olefin to the maleic anhydride is from about 1:1 to about 5:5 and the molecular weight of the copolymer is from about 5,000 to about 100,000, the anhydride moieties of the copolymer being substantially intact.

International Classification:

C02F 510

US Classification:

210701

Abstract:

A method for dispersing high molecular weight hydrocarbon material in an ethylene water quench tower, the method comprising the step of: introducing a deposit inhibiting amount of a dispersant into the ethylene water quench tower, the dispersant comprising a copolymer of a first monomer and a second monomer, the first monomer being selected from the group consisting of butyl methacrylate, lauryl methacrylate, stearyl methacrylate, and decyl methacrylate-2-ethylhexyl methacrylate, the second monomer being selected from the group consisting of diethyl-aminoethyl methacrylate, dimethyl amino-ethyl methacrylate, phenyl aminoethyl methacrylate, butyl aminoethyl methacrylate, and propyl aminoethyl methacrylate.

Carl T. Rowe - Missouri City TX

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

C10G 916

US Classification:

208 48AA

Abstract:

An improved process for inhibiting the formation and deposition of polymer-based fouling materials after caustic scrubbing of hydrocarbon streams contaminated with oxygenated compounds with a basic washing solution having a pH>7 comprising adding to the hydrocarbon stream after caustic scrubbing a sufficient amount for inhibiting formation and deposition of polymer-based fouling materials of a composition comprising at least one hydrazide compound characterized by the formula ##STR1## where R is selected from the group consisting of H, NHNH. sub. 2, and ##STR2##.
