铬盐的清洁生产——无钙焙烧生产红钒钠新工艺

Chromic Compound's Cleaner Production ——the New Process of Roasting Chromite without Calcium to Produce Sodium Bichromate

经工艺实验证实无钙焙烧生产红钒钠新工艺应用于我国铬盐生产行业 ,可从根本上改变铬盐生产对环境的严重污染。预测 1 0kt/a无钙焙烧生产红钒钠新工艺生产装置的建设投资、产品吨耗、外排废物量等数据。

New roasting process for producing sodium bichromate without calcium, which is applied in chromium compound production in China,is proven in commercial experiment. It solely change situation that serious pollutionto environment is caused by chromium compound production. Construction cost, consumption figures per ton product and waste discharge quantity etc. are forecasted for 10,000MTPY new roasting process unit for producing sodium bicarbonate without calcium.
