Project Plan: Target Date, Calendar Days (31 days), Production Days (days): 30 days of production; Planned maintenance and other factors: 1 day. Production plan – Pure soda ash (t): 27,000 – 27,500; Ammonium chloride (t): 29,200 – 29,700; Liquid ammonia (t): 8,790 (daily output of 293 t) – 8,800 t; Bituminous coal (t): 15,000 – 14,784. Plans for major material consumption: Raw coal required per ton of ammonia produced: 1,700 – 1,680 kg/t; Medium-pressure steam required per ton of ammonia: 600 kg/t; Steam required per ton of soda ash: 1.6 – 1.55 t/t; Electricity required per ton of ammonia: 1,350 – 1,350 KW·h/t; Electricity required per ton of soda ash: 2,252 – 2,200 KW·h/t; Salt required per ton of soda ash: 1.18 – 1.18 t/t; Ammonia required per ton of soda ash: 355 – 345 kg/t; Coal required per ton of steam: 180 – 180 kg/t; Electricity required per ton of steam: 2,019 KW·h/t. Electricity required for raw material supply: 6,200,000 KW·h. For caustic soda: 11,880,000 KW·h; for synthetic ammonia: 1,350,000 KW·h; for water vapor generation: 1,600,000 KW·h. Total: 21,030,000 KW·h. Anthracite coal (t): 20,000, of which 4,000 is from Hunan; Planned consumption this month: Shanxi coal – 11,250 t, Hunan coal – 3,750 t. Bituminous coal (t): 5,000 t; Low-sulfur coal with high calorific value: 8,000 t; High-volatility bituminous coal (used for raising furnace temperature): 100 t. Industrial salt (t): 6,000 t of dry salt, 27,000 t of wet salt. Purchased liquid ammonia: 825 t, amount may vary depending on prices. Plastic bags: 550,000 units. Sales plan: Pure soda ash (t): 27,500 t; Ammonium chloride (t): 17,000 t for internal use as wet ammonium chloride; some of it will be converted to dry ammonium chloride, with the excess wet ammonium chloride stored for winter use

The table above shows the production plan for a certain alkali plant for a particular month. The actual progress is basically in line with this plan. I would like to ask experts about which areas of machine and material consumption could be better controlled! At the same time, you might as well share your main material consumption figures.
