摘要:This paper presents a case study of process integration for a Brazilian biodiesel commercial plant water reuse by using the P+WATER method coupled with Water Sources Diagram (WSD). The process flow diagram of biodiesel plant was simulated considering different operation conditions for transesterification unit, the biodiesel refining unit, and the glycerol recovery unit. WSD was employed to select the main scenarios of waste stream reuse. Statistical techniques were applied to assess the operation cost of each scenario and the respective opportunity to reduce the water consumption by water reuse. The most promising scenarios of waste stream reuse were compared using the P+WATER method to evaluate the opportunity of being really introduced in the industrial plant.
