Gas-phase refrigeration

Multi-Objective Optimization of Multi-Stage Gas-Phase Refrigeration Systems... [Pg.237]

Keywords Gas-phase Refrigeration, Dual Independent Expander Process, Liquefied Natural Gas, NSGA-II. [Pg.238]

In this section, optimization of nitrogen cooling with a single gas-phase refrigerant (N2) for multiple objectives using MPMLE, HYSYS and NSGA-II is demonstrated first. Then, the MOO of the dual independent expander process for liquefaction of natural gas is presented. Both processes are considered for typical industrial conditions. [Pg.247]

In this section, four exercise problems are given based on the gas-phase refrigeration system discussed in this chapter. The degree of difficulty increases from problem 1 to 4. Readers can tackle the first three problems with any one of the following three assumptions (i) a constant Cp value - a very simplified approach (ii) Cp is a function of temperature only (i.e., neglect the pressure dependence of Cp) - a reasonable approximation and (iii) use the enthalpy and Cp correlations given below - very close to the real case. The solutions to problems 1 and 2 are available in the file GasPhaseRefrigeration.xls in the folder Chapter 8 on the CD. [Pg.271]

It is required to cool a 1000 kmol/hr of nitrogen gas stream at 2000 kPa from 30 °C to -17 °C using a single stage gas-phase refrigeration process shown in Fig. 8.E1. [Pg.273]
