    Abstract:From the view point of the ratio of cost to characteristic, the design of control system used in recycling unit was analyzed. Energy saving and emission reduction should be taken into account in both process system and automatic instrument system, and these two parts are the emphasis in current design and research work. In this article, the analysis was carried out in automatic instrument aspect.

    Keywords:ratio of cost to characteristic, recycling of base liquid, design of automatic control engineering, emission reduction

    1 节能减排措施性价比

    精对苯二甲酸(PTA)是重要的石油化工产品，是生产聚酯(PET)的主要原料。而在PTA精制生产过程中将产生大量的PTA母液，母液中PTA颗粒的存在一方面会造成资源浪费，另一方面增大了母液的COD含量，加剧了水的污染，增加了后续水处理工艺的负担。以往业主对于这部分的处理并不重视 ......
