determination of Mass Separating Agent flows using the Mass exchange grand composite curve
Chemical Engineering Research & Design, 2005Co-Authors: Duncan M Fraser, M Howe, A Hugo, U V ShenoyAbstract:In this paper we set out the principles for using the grand composite curve (GCC) of Mass exchange network synthesis (MENS) for selection of external Mass Separating Agents (MSAs). These principles enable us to systematically choose between alternative external MSAs as well as the minimum flowrate for each MSA selected. This paper emphasizes that the cheapest MSA is not necessarily the one with the lowest cost per unit Mass of MSA, but rather the one with the lowest overall cost of removal of the Mass load, which depends on both the MSA cost and its permissible concentration change. It also demonstrates the importance of consideration of the composition levels of the MSAs in relation to the target compositions of the rich streams and to the capital cost implications of the resulting Mass transfer driving forces. In this respect the use of the GCC is superior to procedures developed so far. We illustrate the principles presented by application to two example problems.

simultaneous synthesis of Mass exchange networks for waste minimization
Computers & Chemical Engineering, 2005Co-Authors: Chengliang Che, Pingsung HungAbstract:Abstract The paper deals with the synthesis problem of Mass exchange networks (MEN's) for waste minimization by adopting a mathematical programming approach based on the stage-wise superstructure representation of the MEN's, analogous to the one introduced by [Yee, T. F., & Grossmann, I. E. (1990a). Simultaneous optimization models for heat integration. I. Area and energy targeting and modeling of multi-stream exchangers. Computers and Chemical Engineering 14, 1151; Yee, T. F., & Grossmann, I. E. (1990b). Simultaneous optimization models for heat integration. II. Heat exchanger network synthesis. Computers and Chemical Engineering 14, 1165] for synthesis of heat exchange networks (HEN's). This stage-wise superstructure-based representation cannot only handle multiple transferable components and reactive Separating Agents directly, but also be extended to include regeneration networks straightforwardly. Not using any heuristics that are based on the concept of pinch points, the proposed superstructure-based representation for MEN's is formulated as a mixed-integer nonlinear programming (MINLP) optimization model, and therefore the operating cost for the external lean Mass Separating Agents as well as the regenerating Agents and the annualized equipment cost for exchange units can be minimized simultaneously. Four benchmark examples from literatures—including those with single recovery component, multiple waste components, reactive Mass Separating Agent, and regenerating streams—are examined to illustrate the applicability of proposed approach for synthesis of various MEN's.
