I’m seeking help from experts who are familiar with chemical engineering simulation software to explain the logic behind the simulation steps

This is a programming code for the operation logic of a chemical processing equipment. According to the description provided in this code, its operation logic is as follows: First, the name of this program is “ERO”, and its weight value is “10”. The procedure is described as follows: “When the outlet temperature of the atmospheric pressure furnace is greater than 300°C, the crude oil flow is switched to an open circuit, and the valve connecting the residue oil to a storage tank is opened.” Close the valve of the startup circulation line. Open the valve for crude oil entering the unit. ”This means that when a certain condition (the outlet temperature of the atmospheric furnace is greater than 300°C) is met, a series of operations will be carried out. Then there is the exit condition, which defines when the program stops running. When all four conditions—VAL >= 1.00, VAL >= 1.00, and VAL = 300.00—are met, the program will cease to run. The evaluation target is used to determine whether this program is executed correctly. It is the same as the exit conditions; in other words, the program can be considered successful only when it is executed successfully and meets these conditions. The other properties, such as \"AbsoluteSequence\", indicate whether this policy needs to be executed in sequence. "ExecuteScriptEntered, ExecuteScriptSuccessfully, and ExecuteScriptFailed are scripts that need to be executed under different circumstances. "GoToEndFailed","IsDirectlyDeductScore" are some settings related to failed policy execution and scoring. In general, this code essentially describes a process: under certain conditions, a series of operations are carried out until specific termination conditions are met; there are also corresponding measures in place for errors that occur or when the program execution fails. .
