Methanol production from natural gas and methanol production from coal
Thread Content
Please discuss your respective production costs. At present, most of the methanol imported comes from natural gas in the Middle East; due to low oil prices, the cost of producing methanol is also low. Let’s discuss each party’s cost structure.
It’s too complicated; the topic is too broad to explain clearly
Cost of methanol produced from coal (yuan/t, USD/t): Raw coal price: 150, 250, 350, 450, 500, 600. Cost of methanol production: 853.9, 1065.9, 1277.9, 1489.9, 1595.9, 1807.9. Total cost of methanol: 987.3, 1119.9, 1411.3, 1623.3, 1729.3, 1941.3. Equivalent in USD: 139.1, 168.9, 198.8, 228.6, 243.6, 273.4. Note: (1) 1 USD is equivalent to 7.1 RMB； Self-built thermal power plants meet 60% of the electricity demand ； The methanol production capacity is 600,000 tons per year, with fixed asset investment amounting to 2.54 billion yuan (excluding off-site projects). (2) 1.52 t of raw coal and 0.6 t of fuel coal are required per ton of methanol produced ； 6.5MPa water-coal slurry gasification technology ； Lurgi water-cooled–air-cooled methanol synthesis technology. Cost of producing methanol from natural gas: Price of natural gas in yuan per m3: 0.8, 1.0, 1.2, 1.4, 1.6. Manufacturing cost in yuan per ton: 137, 161.6, 155, 161.6, 173, 162.0, 201, 162.29, 16. Total cost in yuan per ton: 1567.6, 1764.6, 1961.6, 2158.6, 2355.6. Converted to US dollars: 220.8, 248.5, 276.3, 304.0, 331.8. Note: (1) 1 US dollar is equivalent to 7.1 yuan ； The methanol production capacity is 600,000 tons per year, with fixed asset investment of 1.61 billion yuan. (2) The natural gas consumption for 1 ton of methanol is 900 m3/(CH4 95%). Based on two domestic plants already in operation with a capacity of 200,000 t/a and another plant under construction with a capacity of 850,000 t/a (with a natural gas consumption of 888 m3/a), estimates have been made for the natural gas consumption and investment requirements for a plant with a capacity of 600,000 t/a. (3) Natural gas conversion employs a technology that combines steam reforming and partial oxidation.
In 2008, there was an article in the fertilizer industry that conducted a competitive analysis of methanol production using lignite from eastern Mongolia in China and natural gas from the Middle East; it contains quite a lot of information, so it’s worth taking a look at.
