Water reuse in cooling system at North Gas Company

Abstract

Increasing and expanding oil and gas processing was accompanied by high demand on water. As a crucial element for both life and agriculture, water sources have to be kept unpolluted and preserved from the pollutant and high consumption from such industries. Thus, came to exist water re-use. Before water re-use can be optimized within a natural gas processing facility, all process water streams and utility water streams must be considered to operate in an integrated fashion that minimizes the water intake and discharge. and water treatment. The cooling system in the North Gas Company is the most demanding unit in terms of water requirement. In this research a water treatment unit is proposed to eliminate and reduce water and pollutants discharged to the Zab channel and well as minimize the water intake to the North Gas Company. For this purpose, an RO units are designed to treat the effluents and the makeup water using IMSDesign 2017 provided by Hydranautics. The optimum membrane type was found to be CPA6 MAX; a brackish water high rejection membrane that has a production rate of 8800 gallon/day and 440 ft2 area.
