Improvement of quality of recirculated water supply of oil refineries

Abstract

The relevance of this work is associated with the need to reduce the volume of water used by returning it to the start of the technological process. Thus, the work aims to improve the quality of the recycled water supply to petrochemical and oil refineries, in particular Atyrau Refinery LLP. This article provides data on purification of blowdown water by reverse osmosis method. A pilot reverse osmosis unit with a capacity of 600 l / h has been manufactured and a technological scheme for purification to standards that meet the requirements of make-up water has been developed, as well as a technical task for the design of industrial recycling water supply systems and appropriate recommendations have been provided.
