1 概述 化学工业是浙江经济的支柱产业之一。经过40多年建设发展。已经具备了较好的经济技术和物质基础,基本形成化学矿采选、石油炼制、基本化学原料、化肥、农药、有机化工、合成材料、橡胶加工、化工机械、化工试剂、磁记录材料等门类较为齐全、产品品种繁多的集科技、设计、生产和经营贸易及技术信息服务为一体的完整而开放的工业体系。据1995年的第三次工业系统普查,浙江省全社会产值在100万元以上的化工企业(包括轻工系统的石油化工和医药系统的医药化工)共有9807家,工业总产值达到790亿元,占全省工业经济比重的14％。 目前浙江省化工产业主要分布以下几个领域: (1)化工原料:硫酸、盐酸有一定的生产规模,硝酸暂无生产。纯碱产量10万吨/年,烧碱产量为33万吨/年。 (2)石油炼制:镇海炼化厂炼制能力1200万吨/年。 (3)农用化工:化肥以小氮肥为主,有少量中氮。化肥产品以碳铵为主,复合肥和磷肥主要是低浓度的普钙等产品,钾肥生产尚未实现工业化。年产农药5万吨,产量居全国第二,但产品科技含量不高。
1 Overview The chemical industry is one of the pillar industries of the Zhejiang economy. After more than 40 years of development. Already has a good economic and technical and material basis, basically formed a chemical ore mining and selection, petroleum refining, basic chemical raw materials, fertilizers, pesticides, organic chemicals, synthetic materials, rubber processing, chemical machinery, chemical reagents, magnetic recording materials, etc. We have a complete and open industrial system that integrates technology, design, production and trade, and technical information services. According to the third survey of industrial systems in 1995, a total of 9,007 chemical companies with a total output value of over 1 million yuan in Zhejiang Province (including petrochemicals for light industrial systems and pharmaceuticals and chemicals for medical systems) had a total of 9,007, and the total industrial output value reached 79 billion yuan. , accounting for 14% of the province’s industrial economy. At present, Zhejiang’s chemical industry is mainly distributed in the following areas: (1) Chemical raw materials: Sulfuric acid and hydrochloric acid have a certain scale of production, and nitric acid is temporarily unavailable. Soda ash production was 100,000 tons/year, and caustic soda production was 330,000 tons/year. (2) Petroleum refining: Zhenhai refinery has a refining capacity of 12 million tons per year. (3) Agricultural Chemicals: Fertilizers are dominated by small nitrogen fertilizers with a small amount of nitrogen. Fertilizer products are dominated by ammonium bicarbonate, and compound fertilizers and phosphate fertilizers are mainly products with low concentrations of calcium sulphate. Potash fertilizer production has not yet been industrialized. With an annual output of 50,000 tons of pesticides, the output ranks second in the country, but the product technology content is not high.
