青岛黄海海藻工业公司把节能降耗摆上重要位置,狠抓以节能为中心的技术改造和技术进步,企业效益、发展速度和后劲同步增长。1992年1～9月份实现销售收入4891.5万元,完成利税350.6万元,出口创汇459.5万美元。近年来,随着能源和原材料涨价、市场竞争日趋激烈等形势的发展,海藻行业受到巨大冲击。该公司从现实出发,积极采用新技术、新工艺、新设备、新材料,不断为节能工作“输液”。1991年他们投资60万元,对主要耗能设备甘露醇蒸发器进行双效改三效的技术改造,对废汽予以回收利用,年节约蒸汽11250t,节约价值56.25万元。1992年他们又投资490万元,与国家海洋局杭州水处理中心联合开发电渗析反渗透项目,研究膜法制取甘露醇新工艺。该项目完成后,每生产1t甘露醇可比原工艺节约蒸汽60％。收率提高15％,节约价值高达239.6万元。在加快技改
Qingdao Huanghai Seaweed Industrial Co., Ltd. put energy-saving and emission reduction in an important position. Paying close attention to energy-saving technological innovation and technological progress, the Company’s efficiency, development speed and stamina increased simultaneously. From January to September 1992, the sales revenue was 48.915 million yuan, the profit and tax was 3.506 million yuan, and the export volume was 4.595 million U.S. dollars. In recent years, with the energy and raw material prices, the increasingly fierce market competition and other developments, the seaweed industry has been a huge impact. The reality of the company starting from the active use of new technologies, new processes, new equipment, new materials, and constantly work for the energy-saving “infusion.” In 1991, they invested 600,000 yuan to carry out the technical renovation of double-effect and three-effect conversion of the main energy-consuming equipment mannitol evaporator. The waste gas was recycled and used, saving 11250 tons of steam and saving 562,500 yuan. In 1992, they invested 4.9 million yuan to jointly develop the electrodialysis reverse osmosis project with the State Oceanic Administration Hangzhou Water Treatment Center to study the new mannitol production process by the membrane method. After the completion of the project, each production of 1t mannitol than the original process to save steam 60%. Yield increased by 15%, saving up to 2.396 million yuan worth.
