Green demulsifiers useful for demulsifying emulsions of water and crude oil are made by reacting together an alcohol, a multifunctional acid and/or anhydride, and a fatty acid, and optionally a polyol that is polyethylene glycol and/or polypropylene glycol. The green demulsifier has ester bonds between the reactant moieties. These ester bonds can hydrolyze which results in relatively high biodegradation.

Methods of designing green demulsifiers

An N-vinyl amide polymer is disclosed. The N-vinyl amide polymer is a reaction product of: a monomer component comprising an N-vinyl amide; and a chain transfer agent of the formula:

Hydrate inhibitors

A stabilized paraffin inhibitor/pour point depressant (PI/PPD) product formulation is described which includes a copolymer having a monomer selected from the group consisting of alkyl acrylate polymers, alkyl methacrylate polymers, and combinations thereof, where the copolymer comprises vinyl acetate and the product includes an ethylene-based copolymer. The presence of the vinyl acetate stabilizes the product to prevent or inhibit the ethylene-based copolymer from separating out of the product. The product is useful to reduce paraffin deposition and/or improve flow characteristics of petroleum fluids, such as crude oil.
