化工生产是一个复杂的流程,在生产过程中由于不同的化学工业所用的原料与所得的产品不同,导致各种化工过程也是千差万别。在生产过程中大致包括三个步骤即对于原材料的提前处理和准备、具体的化学反应、生成产物的分离与提纯过程。根据反应的特点和工艺条件的不同,可供选择的反应器类多种多样。化工生产工艺流程体现了原料转化为产品所采取的化学和物理的方式,化工生产中的工艺流程是多种多样的。 Chemical production is a complex process, due to the different chemical industry raw materials used in the production process and the resulting product is different, leading to a variety of chemical processes are varied. In the production process roughly consists of three steps that is, for the processing and preparation of raw materials in advance, the specific chemical reaction, separation and purification of the resulting product. Depending on the reaction characteristics and process conditions, a wide range of reactors are available. Chemical production process reflects the raw materials into products taken by the chemical and physical methods, chemical production process is diverse.
