Founded in 1958 and now subordinated to CNOOC, CNOOC Tianjin Chemical Research & Design Institute was one of the key scientific research institutes under the former Ministry of Chemical Engineering of P.R.C. It is a comprehensive research institute, which integrates R & D, product development, production and sales, engineering design and EPC, and industrial consultation service, covering an area of 200,000 m2, with more than 600 employees. This institute is mainly engaged in the research of industrial water treatment, inorganic chemicals, catalysts and supporters. By the time of its 50th anniversary, there had more than 1000 technological achievements, among which 134 of provincial level or above, 11 of National level, and 76 authorized patents. Moreover, it has National Research and Promotion Center of Industrial Water Treatment Engineering and Technology as well as National Laboratory for Petrochem Industrial Water Treatment. Four national industrialization demonstration projects of high and new technology are also completed in its hands, including new-type industrial water treatment chemicals with annual production capacity of 150,000 tons, specialty chemicals for industrial water saving at a rating of ten thousand tons, three-way catalysts for the purification of auto exhaust with annual production capacity of 3 million liters, and annual production of 800,000 tons of Lithium hexafluorophosphate used for lithium ion battery. It has produced and sold various kinds of three-way catalysts for petrol-driven automobiles such as China ? more than 1 million liters in total.
