First winning bidder for the EPC contract for the methanol synthesis unit of Xinjiang Shanneng Chemical Co., Ltd.’s 800,000 tons per year coal-to-olefins project in Wucaiwan, Zhundong: China Chengda Engineering Co., Ltd. Bid price: 509,956,551 yuan. The methanol synthesis unit uses the Praxair low-pressure methanol synthesis technology, with raw materials consisting of the purified gas from upstream purification units and green hydrogen from electrolysis water generation units. Through processes such as syngas compression, methanol synthesis, methanol distillation, hydrogen recovery, and waste heat power generation, MTO-grade methanol is produced, along with high-quality hydrogen as a by-product; meanwhile, the waste heat from the synthesis reactions is utilized to generate steam for power production. The methanol synthesis plant comprises 5 core processes along with supporting auxiliary facilities, namely the syngas compression system, methanol synthesis system, methanol distillation system, hydrogen recovery system, and waste heat power generation system. Product scale: MTO-grade methanol (on a pure basis) of 2.2 million tons per year, corresponding to an hourly production capacity of 275,000 kg/h (based on 100% methanol).
