Second Methanol Unit Based on Coke Oven Gas

The 120 000 t/a methanol project based on coke oven gas designed by the Second Design Institute of Chemical Industry started production in Kingboard (Hebei) Coking Co., Ltd. on Sept. 5. The product reached the standard for AA-grade products in the United States. The capacity of this unit is 40 000 t/a higher than the first methanol unit based on coke oven gas in China complete in Qujing, Yunnan province in December 2004. (CCR2004 No. 24)      Kingboard (Hebei) Coking Co., Ltd. owns a stamping coke oven with a capacity of 1.0 million t/a coke. The methanol unit using coke oven gas as raw material started construction in April 2004. Patent technology and equipment from the Second Design Institute of Chemical Industry are used. Fuel gas for the oven itself and gas for the methanol production can be adjusted in a flexible way. Environmental pollution caused by discharged coke oven gas is therefore solved and the dual purpose of controlling environment and transforming wastes into valuables is achieved.      Kingboard (Hebei) Coking Co., Ltd. is funded by Hong Kong Kingboard Petrochemical Co., Ltd. It is located in Neiqiu, Hebei Province in the north of China with rich coal resources and convenient transportation. Hong Kong Kingboard Petrochemical Co., Ltd. owns production facilities of formaldehyde and downstream products in China mainland. To solve the problem of the drastic cost increase in the formaldehyde production caused by the price rise of raw material methanol, it has constructed the Kingboard (Hebei) coking project that can both produce high-quality metallurgical coke and use coke oven gas to produce methanol.     Hong Kong Kingboard Petrochemical Co., Ltd. is very active in China mainland in the past 3 years. It is constructing a 600 000 t/a methanol project in collaboration with CNOOC. It once planned to construct a 750 000 t/a methanol project in Chongqing in the southwest of China and a chemical fertilizer plant in Qinghai in the northwest of China.
