SYSTEM CONFIGURATION PRELIMINARY TESTS AND MULTIPLE INJECTION feedstock in the process crude oil distillation

摘要

1. A process for the distillation of crude oil, including the following: i) hydrocarbon crude oil is passed into the pre-evaporation vessel maintained under conditions which allow for separation of crude liquid obtained as a result of pre-evaporation, and the vapor resulting from the preflash; ii) passes the liquid resulting from the preheat evaporation in an oven maintained under conditions that provide heating and partial vaporization of said liquid; iii) pass the heated effluent from the furnace in the lower part of the distillation column maintained under conditions fractionation; iv) passed steam resulting from the preflash in distillation column zone at the bottom of the stripping zone located below the entry zone effluent stream oven, and v) passing the water vapor in the distillation column zone, at the bottom of the stripping zone, thereby exiting from the furnace that the liquid stream is contacted with steam and the steam formed as a result of pre-evaporation in a stripping zone under conditions sufficient for the stripping liquid leaving the furnace potoka.2. The method of claim. 1, wherein the vapor resulting from the pre-evaporation is passed directly to the distillation column, while directing pechi.3 bypassing. The method of claim. 1, wherein the vapor resulting from the preflash is heated in a convective furnace tube bundle prior to passing it to the distillation kolonnu.4. The method of claim. 1, wherein the vapor resulting from the preflash on
