I want to optimize my product stream in aspen, I have set the cnstraints but I am struggling to determine which blocks blocks to put as the manipulated variables. Like is there a way that can help me set the manipulated variables and their limits or do i just choose randomly? Please help me as soon as possible.
What are you trying to optimize? What is the purpose of the simulation? Usually you create an "objective function" that defines what you are trying to maximize or minimize (eg profit or concentration of product/byproduct) and constraint like Max and min temperature/pressure feed rate etc.
For a blending problem you put a value on all of the products and a cost for all of the feeds, Perhaps a few minimum and/or maximum limits on production of some of the products and the blender/optimizer will run up to constraints.
Hello Kgaogelo Maake ,
Can you provide more details about your process?, maybe you could share part of the flowsheet in order to get a better insight. Otherwise, you always can determine the degrees of freedom of your process and set the design variables (manipulated ones).
