Abstract
A trend of diverse demand for fine chemical has made the chemical industry that was typical mass production industry apply multi products type production. Multi products tyqe production technology with high quality has been a state of the art. Especially the life cycles of the fine chemical and Pharmaceutical Products have been shorter than their production plant life cycle. The design phase of the multi products type production plant is important phase to decide the value of the plant through its life cycle. The current design factors of the multi products type production plant are as follows; Clarification of the design specification including product mix, adoption for future change of the product types, and realization of a flexible operation. We made investlgation on these factors according to the technical aspect, the managing aspect and the organization aspect. We are emphasizing the effectiveness of introducing process simulation in the design phase with showing an example of pipeless plant design.
