Please help determine the cost of producing 100,000 tons of methanol per year using coke oven gas as raw material
Thread Content
The syngas compressor is driven by a turbine; what are the respective cost allocations for water, electricity, gas, labor, and depreciation? First, I would like to express my thanks!
It’s available on the forum; give it a thorough search. Methanol production costs and specific consumption using coke oven gas as raw material: Item, Specific Consumption, Unit Price (yuan), Unit Cost (yuan/ton). Coke oven gas: 2150 m3, 0.160, 344; Cooling water: 298.8 t, 0.2, 59.76; Electricity: 941.6 kW•h, 0.4, 376.6; Steam: 0.106 t, 60, 6.36; Fusel oil: -6.8 kg, 1, -6.8; Catalysts and chemicals: 46.4; Labor: 30; Depreciation and administrative expenses: 179.9; Total: 1036.22. The figures above are based on calculations for this region only and are for reference purposes. Last edited by kaisl1314 on 2007-12-18 at 17:31
Thank you. I have reviewed this material, but I’m not sure whether the syngas compressor in this device is driven by an electric motor or a turbine, as both gas consumption and electricity consumption can change. Nevertheless, I truly appreciate your response.
Both the compressors for air separation and the compressor for synthesis are driven by turbines. What is mentioned on the 1st floor refers to a plant with a capacity of 200,000 tons per year.
