A study on computer aided process integration system design for chemical batch process development

for meeting the demands of dynamic characteristics and product quality control for chemical batch process, an approach of computer aided process system integration was proposed. The technology of process state monitoring and product quality control were carried out on a kilogram scale laboratory chemical process, micro-plant based on the construction of apparatus hardware and software for integration. The proposed approach and technology were then applied to synthesis process of ethyl p-hydroxyl benzoate. The results prove that the proposed approach and technology are feasible and can be practical in chemical batch process monitoring and product quality controlling.
