七效真空制盐工艺

Seven-effect Vacuum Salt Production Technology

因能源价格的上涨,探索一条适合国情的低消耗的七效制盐新工艺。结果显示,正常情况下是增设高温高压的首效,原有六个效基本不动,七效转六效汽耗下降10%以上,效益可观。

In response to rising energy prices, explore a new technology of Seven-effect salt production suitable for China. The results showed that, under normal conditions, it is the first effect to add high temperature and high pressure, the original six effects are basically unchanged, and the steam consumption of Seven-effect is more than 10% lower than that of Six-effect, with considerable benefits.
