Oily water emulsification as the method of its pre-treatment for utilization via co-combustion

Abstract

Oily water can be the side product of many processes, like crude oil processing and transportation leakages, industries such as steel industry, machine industry, petroleum refinery, petrochemical industry, textile industry, metal industry, pyrolysis etc. It seems to be the difficult to dispose waste. Although several treatment methods have been developed, many times additional water disposal installation is required. When the main process consumes natural gas, to simplify oily water utilization, the method of its direct injection to the natural gas burner is suggested by the paper authors. To provide the proper combustion and the mixture homogenization, emulsification was proposed. The aim of the research was to find the optimal recipe from the stability point of view, taking into account technical and economic conditions. The article covers the variety of surfactants examination for the water-hydrocarbons mixture emulsification, including the surfactants concentration optimization.
