Segregated Targeting for Resource Conservation with Dedicated Sources for Batch Process

Abstract

Conversation of natural resources is one of the most important steps towards sustainability and market competitiveness. Process Integration techniques have been successfully applied for conserving natural resources. High value-added products are the best suited in batch processes. The conservation of natural resources in batch processes is an important concern. A segregated targeting problem for the batch process is presented in this paper. This paper is focused on segregated targeting problems for optimal use of resources in the batch process through Pinch Analysis. The segregated targeting problem consists of internal sources, resources, dedicated sources and demands. Resource and dedicated sources of a given zone are used by demands of that zone only for a given period of time. Resources are time-independent and with no flow restrictions. Internal sources are also time-independent. Internal sources can be optimally used by any zones in a given time interval. An algorithm is developed so that internal sources can be used in such a way as to minimize resource requirements. This algorithm can be applicable for both semi-batch and batch processes. The applicability of the proposed algorithm is demonstrated through an illustrative example.
