Analysis of manufacturing costs for methanol production from coke oven gas
Thread Content
For a methanol plant with an annual capacity of 100,000 tons, if the coke production is only 600,000 tons per year, what is the cost associated with consumption in this case? For example: maintenance costs, electricity consumption, labor costs, auxiliary materials, steam, and water consumption. I would appreciate the advice from experts.
The cost is high; it must be losing money now
It may vary from one place to another; it’s just that no one shares good methods
It will be produced soon! Explore slowly!
Stop thinking about it – it’s a huge loss; even 1 million tons of coking isn’t enough to enable 100,000 tons of methanol to be produced at full capacity.
If the full-production cost is not achieved, it will increase. 1. The cost of coke oven gas depends on the price per standard cubic meter, which is generally between 0.3 and 0.5 yuan/Nm3. The specific consumption is 2000 Nm3, with a cost of 600 to 1000 yuan. 2. For 100,000 tons of methanol, if the compressors are entirely powered by electricity, electricity becomes the main cost of production; having one’s own power plant can reduce these costs. 3. Steam consumption is the second-largest source of energy consumption after electricity consumption. 4. Other consumptions are relatively low.
It depends on the coal blending ratio and gas production volume. Each situation is different
