Issue of kerosene supply into live reflux flow of main rectification column of atmospheric vacuum pipestill process units

Abstract

. In this article the possibility of suppling the kerosene fraction into the live reflux line of the K-2 column of the atmospheric vacuum pipestill units is reviewed. According to the results of mathematical calculations in the Petro-SIM software, the fraction 140-240°С was determined as optimal for supplying into the top live reflux line of the K-2 column of the atmospheric vacuum pipestill unit. This action makes it possible to reduce the load on the condensing system of the K-2 column of the atmospheric vacuum pipestill units; the heat potential of the hotter kerosene flow also increases, both for heating oil and for generating low-pressure steam. The article describes the advantages of the method.
