Synthesis of MassExchange Networks with Multiple Target MassSeparating Agents Academic Article uri icon

abstract

  • AbstractA systematic procedure is developed for the simultaneous synthesis of primary massexchange networks and their associated regeneration systems, The purpose of the massexchange network is to preferentially transfer certain pollutants from a set of rich streams to a set of lean streams. The regeneration system subsequently regenerates any recyclable lean stream. In this work, we account for the possibility of each massseparating agent to split into a number of substreams with different target compositions. Accounting for this possibility of multiple target massseparating agents introduces additional design degrees of freedom which can provide a significant economic benefit. A mixed integer nonlinear program is formulated and solved to minimize the operating cost of both networks simultaneously. The solution of this program provides the optimal flow rates and composition ranges of all lean and regenerative streams without any prior commitment to the network structure. Subsequently, a network is synthesized to minimize the fixed cost while realizing the minimum operating cost.
