Abstract

The present invention is related to a method for determination of unit operations of a chemical plant for acid gas removal, the method carried out by a computer or a distributed computer system and the method comprising the steps of: providing (S1) a first set of parameters for the unit operations; providing (S2) a second set of parameters for the unit operations based on the provided first set of parameters and based on data retrieved from a database; determining (S3) a digital model of the chemical plant based on the first set of parameters and the second set of parameters, wherein the digital model comprises a system of equations defining the unit operations of the chemical plant; selecting (S4) starting points for an equation-based solution method of the system of equations, wherein the starting points are at least partially selected from the: —i) the first set of parameters; —ii) the second set of parameters; and —iii) the data retrieved from the database; determining (S5) resultant settings for the unit operations of the chemical plant using the equation-based solution method for the system of equations initialized by the selected starting points.
