Transformation Of Energy Saving And Emission Reduction Of Coal Chemical Enterprises Based On Circular Economy

Lunan ghemical fertilizer plant to build the circular economy, this paper realize the energy conservation and emissions reduction as the research object, to reform the energy saving design parameters before and after the actual running situation of sorting and collecting, the project caused by the social economic effect and environmental effect into consideration, the energy saving project implementation of the comprehensive economic benefit analysis.Through corporate energy use and waste emissions data collection and Analysis, investigation of energy conversion rate, and energy consumption is a key component of severe methanol and thermoelectric plants. Methanol plant emissions of6.57xlO7Nm3/a, thermoelectric plant material consumption reached3.96x1O5t/a, water consumption and3.20xl03t/a. Through the material and energy balance calculations for the condensate drain, combustible gases and vapors diffuse separately proposed recovery rehabilitation programs. Which boiler capacity3.03×104t/a of coal, saving8.01x106kWh, the amount of hot water utilization transform1.52xlO4tons of coal can be recycled exhaust gas5.90x108Nm3/a, the amount of1.29x104tons of coal, steam recycling transformation to reduce the amount of3.50x104t/a, the annual volume of0.53x104tons coal. Reduce overall energy consumption of ammonia5.04GJ/t, reducing overall energy consumption of methanol12.46kgce/t, waste heat utilization increased by5.2%; SO2emissions per unit of product decreased0.09kg/t, NOx emissions decreased0.02kg/t.
