Industrial Water Treatment in Refineries and Petrochemical Plants
Gulf Professional Publishing, 1995 , 248 p., pdf , 16.09 MB
This book aims to introduce waste water and cooling water treatments to student and graduate engineers in the oil and chemical industries. It is based on industrial implementation of these treatments and describes operators' experiences in running their own facilities in a number of plants. The following points are developed: an introduction to the vocabulary and chemistry of waste water purification with a discussion of the organic and inorganic pollutants that are inherent to the oil industry; the main sources of polluting effluents characterized according to processes, along with a number of excerpts from discharge standards; the sequencing of treatments as per the three conventional stages of gravity deoiling, physicochemical and biological purifications, with an extension to some cases in petrochemical plants; the potential for recycling some purified effluents that is made possible through tertiary purification; case studies of five leading French refineries; a chapter dealing with the different types of spent caustic and how treatment can be improved; and the definition and implementation of cooling system conditioning processes in order to protect them from fouling, scaling and corrosion. The challenge for both effluent purification and cooling water conditioning is the search for minimum makeup water consumption and consequently optimum effluent recovery in order to ensure better environmental protection.
