Simulation of unit operations of a chemical plant for acid gas removal

A method of determining unit operations of a chemical plant, the method comprising:

• receiving, by a processing device, a first set of parameters for the unit operations;
• identifying, by the processing device, a second set of parameters for the unit operations based on the first set of parameters and based on data retrieved from a database;
• generating, by the processing device, 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, by the processing device, starting points for an equation-based solution method of the system of equations, wherein the starting points are at least partially selected from:
• i) the first set of parameters;
• ii) the second set of parameters;
• and
• iii) the data retrieved from the database;
• and
• determining, by the processing device, 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.
