An alternative disjunctive optimization model for heat integration with variable temperatures

A novel disjunctive model for the simultaneous optimization and heat integration

10 This paper introduces a new disjunctive formulation for the simultaneous optimization and heat integration of 11 systems with variable inlet and outlet temperatures in process streams as well as the possibility of selecting and 12 using different utilities. The starting point is the original compact formulation of the Pinch Location Method, 13 however, instead of approximating the “maximum” ...

Simultaneous optimization and heat integration of chemical processes

A procedure is proposed for simultaneously handling the problem of optimal heat integration while performing the optimization of process flowsheets. The method is based on including a set of constraints into the nonlinear process optimization problem so as to ensure that the minimum utility target for heat recovery networks is featured. These heat integration constraints, which do not require t...

A Double Pipe Heat Exchanger Design and Optimization for Cooling an Alkaline Fuel Cell System

In the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (AFC) (which the electrolyte has cooling role of system) has been considered. Proper control volumes of system with specific qualification have been chosen. Consequently, heat and mass transfer in control volumes have been assessed. Considerations on them and contributed models lead to approve a double tube heat...

Irreversibility Analysis of MHD Buoyancy-Driven Variable Viscosity Liquid Film along an Inclined Heated Plate Convective Cooling

Analysis of intrinsic irreversibility and heat transfer in a buoyancy-driven changeable viscosity liquid along an incline heated wall with convective cooling taking into consideration the heated isothermal and isoflux wall is investigated. By Newton’s law of cooling, we assumed the free surface exchange heat with environment and fluid viscosity is exponentially dependent on temperature. Appropr...
