Abstract: Polymerization inhibitor compositions are provided. The polymerization inhibitor compositions include at least a first inhibitor compound having a stable nitroxide radical and a second inhibitor compound having a hydroxylamine. Methods of inhibiting the polymerization of monomers using the compositions of the disclosure are also provided. The methods of inhibiting polymerization of monomers include a step of adding a composition of the disclosure to the monomer. In some instances, the monomer is an ethylenically unsaturated monomer. Such ethylenically unsaturated monomers include, but are not limited to, vinyl acetate, acrylonitrile, acrylates, methacrylates, 1,3-butadiene, styrene, isoprene, (meth)acrylic acid, and combinations thereof. Methods of preparing the polymerization inhibitors and compositions of the disclosure are also provided.

Abstract: The present disclosure provides compositions and method for controlling fouling in a process for cleaning a hydrocarbon gas. The methods may include adding an effective amount of a composition to a conduit including the hydrocarbon gas. The composition includes, for example, various components, additives, and/or solvents. The compositions and methods may also be used for controlling fouling of equipment used during a process for cleaning and compressing a hydrocarbon gas. The equipment may be selected from, for example, a slug catcher, a scrubber, a suction drum, a compressor, and any combination thereof.

Abstract: The disclosure provides compositions and methods for reducing fouling of a surface in contact with a medium during a natural gas processing procedure. Methods may include adding a composition to the medium, wherein the medium includes an inorganic particle, an organic particle, and/or an inorganic-organic particle, and the composition includes a surfactant. The surfactant may encapsulate the particle. The surfactant may include, for example, a phthalate ester, a naphthalate ester, a tall oil fatty acid, a soya oil fatty acid, sunflower oil fatty acid, canola oil fatty acid, coconut oil fatty acid, cyrene, a trigylceride, or any combination thereof.
