A New Methodology for Automating Waste Minimization Analysis of Batch Processes
نویسندگان
چکیده
The issues of waste generation in batch process plants differ in many aspects to continuous plants. Despite the smaller-scale of processing, complexities from unsteady state profiles, discontinuities, and run-to-run variations make waste minimization in batch plant more challenging. In this paper, we present a systematic methodology for waste minimization analysis of a batch process. The methodology consists of three fundamental elements: process graph (P graph) for process recipe assessment and path flow analysis of waste material and cause-and-effect and functional knowledge for evaluating the process recipe and equipment variables connectivity. The application of the methodology is illustrated through an alcohol washing case study.

Design Synthesis for Simultaneous Waste Source Reduction and Recycling Analysis in Batch Processes
The issues of waste generation in batch process plants differ in many aspects from those in continuous plants. Despite the smaller-scale of processing, complexities from discontinuities and run-to-run variations make waste minimization in batch plants more challenging. In this paper, we introduce an integrated qualitative-quantitative methodology and decision support system, called Batch-ENVOPE...

The issue of environmental sustainability has prompted the batch chemical industries to switch from end-of-pipe treatment to waste minimization as top priority in tackling the pollution problem. In this paper, we introduce a novel simulation-optimization framework that integrates different process systems engineering (PSE) methodologies – process graph (P-graph), hierarchical design strategy, W...
متن کاملMinimization of the Sheet Thinning in Hydraulic Deep Drawing Process Using Response Surface Methodology and Finite Element Method
In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....

متن کاملA New Acceptance Sampling Design Using Bayesian Modeling and Backwards Induction
In acceptance sampling plans, the decisions on either accepting or rejecting a specific batch is still a challenging problem. In order to provide a desired level of protection for customers as well as manufacturers, in this paper, a new acceptance sampling design is proposed to accept or reject a batch based on Bayesian modeling to update the distribution function of the percentage of nonconfor...
