  • ZIEGLER-NATTA CATALYST DEACTIVATION AND NEUTRALIZATION
    Publication number: 20210002393
    Abstract: A solution polymerization process for producing ethylene-based polymer includes introducing ethylene monomer, hydrocarbon solvent, and Ziegler-Natta catalyst into an entrance of a solution polymerization reactor. An ethylene-based polymer is produced by solution polymerizing the ethylene monomer in hydrocarbon solvent. Subsequently, a catalyst deactivator is introduced into the exit of the solution polymerization reactor, thereby producing hydrochloric acid byproduct. The catalyst deactivator includes long chain carboxylate and at least one cation selected from Groups 1, 2, and 12 of the IUPAC periodic table, with the exception of calcium. The catalyst deactivator reduces the effectiveness of the Ziegler-Natta catalyst and neutralizes the hydrochloric acid by forming a chloride salt other than calcium chloride.

  • Method for recovering hydrocarbon fluids from a subterranean reservoir using alpha-glycol containing sulfonated epoxy resin compound
    Patent number: 10876032
    Abstract: Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns ?-glycol containing sulfonated epoxy resin composition and method for preparing said composition. The ?-glycol containing sulfonated epoxy resin composition is made by forming a reaction product comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, followed by converting any unreacted epoxide groups in the reaction product to ?-glycol groups by hydrolysis. Said ?-glycol containing sulfonated epoxy resin compositions demonstrate good solubility in aqueous solutions and are useful for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.
