Conservação de água em refinaria de petróleo: o caso da Revap

Abstract

The main purpose of this works is to present economical and technical analysis, wich are viable to the reasonable use of water and a reduction of sewage in oil refineries. This improvement includes the reuse of effluents in order to assure more flexibility in industrial sewage treatment plants. Nowadays, industries are coming across a scenery of expansion in water consumption, what in the long run can endanger the productive activities. Growth of water comsumption in oil refineries is higger than the improvement in production requiring massive investment in water and sewage treatment. On the other side the environmental agencies through a restrictive legislation are reinforcing laws to prevent larger degradation. On this work we are very concerned about the lack of natural resources, mainly water for future generations. The most recent warnings were presented in the GEO-2000 report, wich has its focus in lack of water and global warming. These two subject will be most important matters to be discussed in the next century. Due to the population growth and its respective need of water, society as a hole must find best practices in water consumption. During the work we realized that industries through simple practices can reduce significantly the use of water and consequent effluent generation.
