Introducing a new parameter for evaluating the degree of integration in cryogenic liquid recovery processes

摘要: Abstract Supplying the required refrigeration is one of most important parameters in design cryogenic liquid recovery processes and different configurations have been introduced order to gain higher recoveries or minimum total cost. However, due advantages disadvantages current invented changeable operating conditions such prices products costs, selection a configuration as best not easy. In this work new parameter for evaluating degree integration introduced. This can evaluate based on recovered from process streams against which gained by sources. The exergy concept was used calculate Integration Degree (IDG). IDG defined two kinds processes; with without external refrigeration. results showed that kind basic variable affect significantly, influences other are significant comparison. Consequently it be said increasing performance integrity increase optimization problems.
