Atmospheric Concentrations of Sulphur Dioxide in and Around a Typical Indian Petroleum Refinery

摘要

Petroleum refineries are large industrial installations that are responsible for the emission of several pollutants into the atmosphere. For most refineries, the numbers of products are limited and fairly well defined, however, the volumes may be different There are refineries that make specialty products such as lubricants and solvents. On a macro scale, the crude oils vary only to a certain extent in their composition. Consequently refinery emissions are mainly related to the raising of energy for the different processes and type of emissions are well defined, viz CO_2, SO_2, VOCs and NO_x However, the major air emission from petroleum refinery is SO_2 since it is evolved in almost every refinery process.
