摘要： Inhibiting coke formation on heat transfer surfaces used to heat or cool a petroleum feedstock at coke-forming conditions. The heat transfer surfaces are treated with an effective amount of S,S,S-trihydrocarbyl phosphorotrithioate to inhibit coke formation on the heat transfer surfaces. The phosphorotrithioate is essentially free from contributing to corrosion and from producing catalyst-impairing by-products.

摘要： Cracked hydrocarbon gases are treated to remove contaminating compounds that react in caustic wash to form the reaction products which cause equipment fouling. The treating of the cracked hydrocarbon gases includes the contacting of a cracked hydrocarbon stream with an aqueous amine solution, prior to caustic washing, to remove carbonyl compounds contained in the cracked hydrocarbon gases. By treating the cracked hydrocarbons with an amine compound prior to caustic washing, the formation and deposition of fouling compounds upon the internal components of caustic treating equipment is inhibited.

摘要： The present disclosure is directed to methods and compositions for controlling undesirable coke formation and deposition commonly encountered during the high temperature processing of hydrocarbons. During the processing of hydrocarbon, coke formation and, in particular, filamentous coke formation can be inhibited by adding a sufficient amount of a boron compound from the group of metal borides, boron oxide compounds, and boric acid which is substantially free of water. The boron oxide compounds are particularly effective, especially when utilized in a non-polar organic liquid carrier.

摘要： In the thermal cracking of or heating of hydrocarbons, for example naphtha, a carbonization reaction incidentally takes place due to the fact that Ni, Fe and Co contained in, for example, the conduits of the thermal cracking apparatus have a catalytically carbonizing action. The aim of the present invention is to effectively suppress carbon deposition promoted by these elements, to provide for the incorporation of an inhibitor element, e.g. Li, Na, Ba, Be, Ca, Mg or their oxides, into the heat-resistant alloy, and to form on the surface of this alloy a carbon deposition suppressing layer which comprises an inhibitor element.

摘要： A method of decoking (decarbonizing) surfaces of a cracking plant in which the cracking furnace is connected to a heat exchanger for cooling the cracked gas mixture, in which steam and air are admitted as a gas mixture to the cracking furnace and then the gas mixture is conducted through the cooler. The cooling medium is thus passed through the cracking gas cooler during the decoking operation while in a first stage the mixture is fed through the device at such a mass flow rate that the temperature of the deposits on the heat exchange surface is approximately at the temperature corresponding to cracking operations while, in a second stage, the gas flow rate is increased to raise the temperature of the deposits on the heat exchange surfaces of the cooler.
