Method for transforming and distilling hydrocarbons. [distillation]
Patent
·
OSTI ID:5386731
A method for the transformation of heavy hydrocarbons comprises a preheating stage for vaporizing the raw hydrocarbons and a main heating stage which consists in heating, in a very regular and gradual manner, the vapors formed during the preheating stage and the gaseous hydrocarbons produced during the main heating stage being successively submitted to the action of catalyzers. The maximum temperature during heating is maintained between 500/sup 0/C, and 700/sup 0/C, and the pressure is maintained below 1.2 kilogrammes per square centimeter. A number of successive cooling stages are included. In these cooling stages, the mixture of gases and vapors issuing from the main heating stage is subjected to the cooling medium, which in the first cooling stage is boiling water at a predetermined super-atmospheric pressure so that the sudden drop in the temperature of the gases and vapors through the first cooling stage between 250/sup 0/C.
