METHOD OF DECREASING COKING OF HEAT EXCHANGER SURFACES

摘要

FIELD: chemical engineering. SUBSTANCE: invention relates to heat exchangers in reactors and/or plants for gas-phase high-temperature conversion of hydrocarbons and other organic compounds. Metal surfaces coming into contact with organic materials are treated with mixture consisting of silicon- and sulfur-containing product and inert (in respect to product) dry gas stream at 300 to 1000 C for 0.5 to 12 hr. EFFECT: prolonged operation period. 12 cl, 10 dwg, 2 tblg
