The cost of gas
Thread Content
I would like to ask the experts: for water-coal slurry gasification and pulverized coal gasification, what is the approximate cost per 1,000 cubic meters of gas? This includes raw materials, water and electricity, labor costs, equipment depreciation, and financial costs, among others. I would appreciate your guidance
I cannot answer this question for you, as regional differences and variations in coal types make it impossible to provide an accurate figure. I will use a project that produces 520,000 tons of urea from water-coal slurry to illustrate the calculations: the raw coal used is washed bituminous coal at 550 yuan per ton, while the fuel coal costs 380 yuan per ton. To produce 520,000 tons of urea per hour, 105,900 Nm3/h of effective gas (CO+H2) is required; approximately 0.68 tons of urea can be produced from 1,000 Nm3 of such gas. Once you take into account electricity costs, water costs, labor expenses, depreciation, and financial costs, you’ll have an idea of the total cost. As for electricity costs, they vary depending on the region and also depend on the setup – for example, whether there is a own power plant in place Are mechanical devices more often driven by electricity or by steam turbines? ), water fees: the same problem exists (is it a water-scarce area? Equipment configuration: more water-cooled or air-cooled units?), Labor costs: these vary depending on the number of employees and local wage standards), Depreciation: this is roughly the same for everyone, Financial costs: these need to be calculated by the company’s finance department based on the amount of loan taken out). So, no one can help you calculate the answer to your question.
Additionally, maintenance costs, office expenses, material losses, and so on must be included.
Thank you all for your answers. Could you please tell me the consumption of water, electricity, steam, raw materials, and labor per thousand cubic meters of gas?
