The process technologies,selection of equipment and its corrosion in the production of potassium sulphate from potassium chloride and ammonium sulphate are discussed. 提出以硫酸銨和氯化鉀為原料，復分解制取農用硫酸鉀的工藝條件及工藝流程，并探討生產(chǎn)中設備選擇及腐蝕問(wèn)題。
A new method of producing comparatively pure potassium sulphate from seawater using inartificial zeolite as the medium of ion exchange was especially introduced. 特別介紹了用天然沸石作為離子交換劑，從海水中制備較純凈的硫酸鉀新工藝。
