Methods and compositions for inhibiting carbonyl-based fouling of basic wash systems. The methods comprise contacting the hydrocarbon stream that is or will be subjected to such washing with water soluble or water dispersible copolymers comprising repeat units of 1) ethylenically unsaturated monomers such as acrylic acid with one or more 2) other repeat units such as alkyl acrylates, allyl ethers, ethoxylated allyl repeat units, etc. In other embodiments, a third repeat unit 3) is present and may comprise a hydrophobic moiety such as a styrene repeat unit. The compositions may be terpolymers comprising repeat units 1), 2), and 3).

Methods and compositions for prevention of fouling in caustic towers

An antifouling dispersant composition having an alcohol polyoxyethylene (EO) ether (EO number 1-14), represented by the general formula (I), wherein R is an alkyl with about 3-20 carbon atoms; and n is 1-14.

Anti-fouling dispersant composition and method of use

Methods are disclosed for reducing oil in water emulsions in coking processes. One exemplary method comprises: providing an aqueous stream with an oil in water emulsion; providing a treatment composition, wherein the treatment composition comprises at least one cationic polyacrylamide; and contacting the aqueous stream with the treatment composition.

Method to treat flushing liquor systems in coke plants

The invention relates to a polymer comprising structural units of formula and formula wherein Methods for preparing and using the polymer are also described herein.

Polymer and methods for preparing and using the same

The present invention concerns a method of detecting cationic polymers comprising: obtaining a target water sample containing a cationic polymer; adding a polymer dispersant solution and a phosphate solution to the target water sample, the polymer dispersant solution is comprised of a polymer dispersant with calcium and magnesium hardness and the phosphate solution is comprised of a phosphate; standing the target water sample; and measuring the turbidity of the target water sample; comparing the turbidity of said target water sample with a calibration curve of the turbidity of samples containing known concentrations of cationic polymers to determine the concentration of cationic polymers in said target water sample.
