The Company was put under the Enterprise Work Commission of the Central Committee of CPC in October, 2000 and under the State-owned Assets Supervision and Administration Commission of the State Council in April, 2003. The Company restructured and merged itself into China National Petroleum Corporation (CNPC) in July, 2007 and has become CNPCs fully-capitalized subsidiary ever since.As an international engineering company integrating various functions of R & D, consultation, design, procurement, construction management, start-up instruction, project supervision, project contracting, etc, CKCECs business scope covers petrochemical, C1 chemical, synthetic material, chemical fiber/textile, environment protection and civil architecture, etc. C1 chemical engineering is CKCECs focused area. CKCEC and CNOOC Tianjin Chemical Research & Design Institute (TCRDI) have jointly developed methanol to stable hydrocarbon technology (MTHc). The process of the MTHc consists of reaction, regeneration and separation unit, wherein the reaction unit consists of etherification and synthesis unit.Main products and by-products are: Stable hydrocarbon, liquefied gas, heavy oil and methane-rich gas. The heavy oil can be further purified to get durene. The Stable hydrocarbon product which contains low sulfur, low nitrogen, low benzene and low olefins, is suitable for high quality blending component of national V and VI gasoline. Durene can be used as raw material for high-grade engineering fiber and plastic polyimide. Due to the excellent resistance of high temperature and low temperature, dielectric, radiation resistance, etc, the polyimide is widely used in aviation, aerospace, microelectronics, nanotechnology, LCD, separation membrane, laser and other fields.The first generation MTHc technology has been successfully used in Inner Mongolia Fenghui Chemical Co. Ltd. 100,000 t/a MTHc plant (phase I). The production is stable and high quality, which is sold to Beijing, Tianjin, etc. The energy consumption of the first generation MTHc technology is 25% lower than other domestic MTHc technologies. Based on successful development of the first generation technology, CKCEC has already optimized the MTHc technology and completed the second generation of MTHc technology by improving energy utilization efficiency. In addition, CKCEC has completed front-end engineering design for several companies. The design capacity of these processes is 200,000 to 250,000 tons stable hydrocarbon product per year. The energy consumption of the second generation of MTHc technology is 40% lower than other domestic MTHc technologies. And the same time, CKCEC is developing an annual output of 500,000 tons of stable hydrocarbon moving bed technology. This technology is expected to be applied and popularized in 2016.Technical characteristics:(1) The technology has two steps including etherification and synthesis, and different catalysts have been loaded in reactors. The cost of catalyst is much lower.(2) As a result of two steps, the reaction conditions can be optimized according to different stages and its reaction mechanism. The operation conditions become more moderate and the product index become more stable.(3) The hot-wall reactor has been used to improve process stability and reliability.(4) Using multiple methods to control temperature and prevent temperature runaway from occurring.(5) The reaction and regeneration using multiple isolation measures to achieve fully automated, operation becomes more safe and convenient consequently.(6)The regeneration period is 22-26 days; the regeneration time is 3-4 days.(7) High methanol conversion rate (99.99%) and liquid yield (36.1%), which reached international advanced level.(8) Application of efficient heat exchanger, energy
