一、前言近廿年来,由于出现能源问题,尤其石油天然气价格增涨多倍,为此从卤水中提取无机盐类都尽量利用当地自然能源的有利条件。例如美国西尔斯湖本是利用人工蒸发获得固体盐类,近年来也改为盐田日晒。等温蒸发和天然蒸发是盐田日晒工艺的应用基础工作,即从蒸发过程中的化学组成变化,水分的蒸失量,盐类析出的顺序、种
I. INTRODUCTION In the past 20 years, due to energy problems, especially oil and natural gas prices multiplied many times, extraction of inorganic salts from brine has made full use of the favorable conditions of local natural energy. For example, the Sears Lake in the United States originally used artificial evaporation to obtain solid salts, and in recent years, it changed to salt-field sun. Isothermal evaporation and natural evaporation are the basic application of the sun-drying process in the field, that is, the change of chemical composition from the evaporation process, the loss of moisture, the order of salt precipitation, species
