Since the beginning of this year, Zhongping Nenghua Lanzhou Chemical Co., Ltd. Luping Chemical Plant has found a way for the exhaust gas containing carbon dioxide, grading and screening the waste residue, and recovering and reusing it after two crushing operations, maximizing energy efficiency and reducing production. Cost, and achieved considerable social and economic benefits.
Fuping Chemical Plant is a methanol production enterprise that uses coal as raw material. It can produce 180,000 cubic meters of exhaust gas containing carbon dioxide per day. The Zhongyuan Methanol Plant, which belongs to Blue Sky Chemicals, is a methanol production enterprise that uses natural gas as a raw material. Due to the high hydrogen content in the feed gas, which affects the chemical reaction rate of methanol synthesis, the plant is forced to release part of the raw gas with high hydrogen content. To solve this problem, the company built a 16-kilometer-long pipeline to transport the carbon dioxide-containing waste gas from Fuping Chemical Plant to the Zhongyuan Methanol Plant. On the one hand, it increased the methanol production of the Zhongyuan Methanol Plant and reduced the production cost. On the other hand, it also reduces the amount of exhaust emissions and improves the quality of the atmospheric environment.
According to reports, under normal production conditions, Fuping Chemical Factory can transport more than 4 million cubic meters of exhaust gas containing carbon dioxide to the Zhongyuan Methanol Plant each month, making the methanol cost of the Zhongyuan Methanol Factory drop by about 200 yuan per ton.
Yuping Chemical Plant also produces a large amount of solid waste during its production, of which the gas slag, coal slurry, and coal gangue have a certain thermal energy value. Through a long period of research and exploration, the plant has classified and screened this part of solid waste, and recycled it, successfully achieving “turning waste into treasureâ€. Estimates show that from March to September this year, the plant was co-mingled with more than 7,000 tons of ash foam, 20,000 tons of small gas slag, 5,000 tons of slag, 6000 tons of coal sludge, and 350 tons of fuel coal daily. It gradually decreased to 200 tons, saving 150 tons of fuel coal every day. This alone can save production costs of 1.47 million yuan per month for enterprises.
