煤化工产业的发展与环境资源约束

"Springing Phenomenon" of Coal Chemical Industry and the Constraint of Environment and Resources

分析了煤化工“潮涌现象”出现的必然性，政府虽然进行了干预，但是“潮声依旧”。预计2010年全国甲醇产能达到5000万吨，则需要煤炭资源1亿吨；而根据现在规划的煤制油项目规模将超过3000吨以上，按4～5吨煤制1吨油、3000万吨产能计算，需要1．2～1．5亿吨煤炭。大型煤化工项目年用水量通常高达几千万立方米，吨产品耗水在十吨以上，相当于一些地区十几万人口的水资源占有量或100多平方千米国土面积的水资源保有量。节能减排的要求也需要煤化工项目尽快“退潮”。环境与资源的约束说明煤化工的“潮涌现象”必须予以制止。

This paper analyzes the inevitability of the ＂springing phenomenon＂ in coal chemical industry. Although the government has intervened, the springing phenomenon has always happened until recently. It is anticipated that the production of methanol will be 50 million tons in 2010 from 100 million tons of coal. The demand of coal is 120 million tons based on the plan of making oil from coal with the ratio of 1 ton of coal to 4-5 tons of coal. The water demand of a large-sized coal chemical plant is up to 10 million m3 , with the water consumption quantity higher than 10 tons for 1 ton of coal, corresponding to the total water consumption of that in the area with the population of 100,000, or the quantity of a country with the area of 100 square kilometers. Coal chemical industry should be regressed as soon as possible, because of the demand of energy-saving and emission reduction. The constraint between environment and resources indicates that the springing phenomenon in coal chemical industry must be prohibited.
