    摘要: The polymerization of monomers may be at least partially reduced or inhibited by introducing an effective amount of an additive. The additive may be or include a first compound: where: R1 and R2 may be or include an alkyl group, an aryl group, an alkyl group having a heteroatom, an aryl group having a heteroatom, and combinations thereof. The hetero atom may be or include sulfur, nitrogen and/or oxygen. R1 may be the same or different from R2. The polymerizable monomers may be or include, but are not limited to styrene, butadiene, isoprene, acrylic acid, acrylonitrile, vinyl acetate, and combinations thereof.

    摘要: At least one pH-sensitive component may contact a refinery stream for measuring the pH of the refinery stream. A light from a light source may be emitted onto the pH-sensitive component, and a detector may detect a first luminescence or color change of chromophore measurement radiated from the pH-sensitive component. A first pH of the refinery stream may be determined from the first luminescence or color change of chromophore measurement.

    摘要: Methods and fluid compositions are described for decreasing or inhibiting foulants within an ethylene plant at a particular location, such as a caustic tower in a non-limiting embodiment. An effective amount of at least one substituted hydroxylamine and an effective amount of at least one aldol inhibitor may be introduced into a fluid feed of the ethylene plant. The aldol inhibitor(s) may be or include a substituted hydroxylimine, a borohydride, and combinations thereof.
