Abstract: A method for inhibiting the formation of fouling materials including contacting hydrocarbon media containing aldehyde compounds with an antifoulant while treating the hydrocarbon media with a basic wash. The antifoulant includes a reducing sugar.

Abstract: A method for the catalytic oxychlorination of ethane to VCM comprising combining ethane and a chlorine source in an oxychlorination reactor in the presence of an oxychlorination catalyst, the reaction conditions being selected to reduce the influence of the oxychloride form of the catalyst, separating the VCM product from the output of the reactor and recycling the by-products to the reactor.

Abstract: 1,2-Dichloroethane is prepared by reacting ethylene, hydrogen chloride and oxygen or an oxygen-containing gas in the presence of a copper-containing catalyst by a process in which first hydrogen chloride and oxygen or an oxygen-containing gas are reacted in the presence of the catalyst, then ethylene is added, and the mixture is reacted in the presence of the said catalyst.

Abstract: A method of inhibiting fouling in a crude ethylene dichloride stream comprises introducing into the stream an inhibiting amount of an antifoulant selected from (A) an acylated amine (e.g., reaction product of polyisobutylene and maleic anhydride) and a polyamine (B) magnesium alkyl aryl sulfonate, and (C) a mixture of A and B.

Abstract: A process is provided for the production of allyl chloride from three carbon atom hydrocarbons (propane and/or propylene) using hydrogen chloride or hydrogen chloride/chlorine mixtures as the chlorinating agent. The process includes reaction steps operated in tandem in separate zones first comprising the reaction of perchloroethylene with hydrogen chloride and oxygen in the presence of an oxychlorination catalyst to give hexachloroethane and water, second comprising the vapor phase reaction of hexachloroethane with propane/propylene feedstock to produce allyl chloride, perchloroethylene, and hydrogen chloride, and third isolating the products of the second step and repeating the first step using as starting materials the thus isolated perchloroethylene and hydrogen chloride.

Abstract: A process for the removal of solid particles from a mixture containing at least one liquid chlorinated hydrocarbon is described. The solids-containing liquid mixture is introduced into at least one hydrocyclone having a downstream separator. The liquid mixture which has been enriched in solids and discharged from the hydrocyclone is preferably subjected to sedimentation of the solid particles, without the use of centrifugal forces. Efficient removal of interfering particles is achieved in this way, together, with long service lives and a minimum of emission.

Abstract: A process for the manufacture of vinyl chloride by the condensation of methyl chloride, obtained from methane or from methanol, followed by an oxychlorination of the condensation products and then by a dehydrochlorination.The condensation of methyl chloride preferably takes place in the presence of a catalyst selected from an aluminosilicate or an oxide, oxyhalide or sulfide of a transition metal of Groups IV, V, VI and VII of the Periodic Table.

Abstract: An improved method and burner apparatus for simultaneously incinerating liquid, dry gas and wet gas streams such as the vent streams in a chemical plant or the like are provided. The method comprises combining the dry gas and wet gas streams, heating the resultant combined stream to thereby prevent condensation from occurring, flowing the heated combined stream through a gas distributing nozzle means, flowing the liquid stream through a liquid atomizing and atomized liquid distributing nozzle means positioned adjacent the gas distributing nozzle means, mixing air with the gas and atomized liquid distributed by the nozzle means, and igniting and combusting the resulting air-gas-atomized liquid mixture. Burner apparatus for carrying out the method is also provided.

Abstract: The present invention relates to a novel process of halogenating aliphatic hydrocarbons which comprises, first non-selectively oxyhalogenating a C.sub.2 -C.sub.6 aliphatic hydrocarbon to a partially halogenated intermediate product having an overall avarage empirical formula in which the atomic ratio of halogen to carbon is greater than 1:1, then vapor phase halogenating said intermediate product to form an end product having an atomic ratio of carbon to hydrogen is at least 2:1; thereby selectively coproducing or consuming hydrogen chloride.

Abstract: Process and apparatus for producing vinyl chloride monomer characterized by conjoint chlorination and dehydrochlorination reactions carried out in the presence of fluidized solids which provide efficient heat transfer within and between the two reaction zones.
