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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
