Advanced combustion, cooling and refrigeration, waste gas treatment, heat integrated separation and case studies

This is an overview of a Special Issue that has been dedicated to the 8th conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction – PRES’05. Twelve papers from the conference have been selected and peer-reviewed and cover various subjects of advancedcombustion, cooling and refrigeration and wastegastreatment. These have been supplemented with heatintegratedseparation and casestudie

T METHOD FOR DISTILLATION COLUMNS

The T method is a newly developed one in distillation calculations which belongs to the class of methods which apply a partitioning of the whole system of equations to be solved. It is similar in nature to the well known B. P. method or theta method, even if, when compared with them, it shows a higher efficiency in reaching the solution. Following the basic ideas of the theta method, the T convergence promoter gives a better estimate of the liquid and vapor molar fractions profiles. As a matter of fact, a better estimate of the temperature profiles, and physical properties is obtained. This situation allows the method to approach the solution by means of quicker convergence. Some explanatory examples are shown in order to demonstrate the feasibility of the proposed method
