Hi, can anyone try to simulate this process by using DWSIM? i need the transfer function model of the process, thanks in advance for any help! The transfer function of the process, Gp is needed, this is a part of designing PID controller

Control Loops: Loop 1 MV. Flowrate of top product CV: Evaporator pressure Loop 2 MV: Flowrate of inlet stream to evaporator CV: Composition of bottom product Loop3 MV Flowrate of the bottom product CV: Liquid level inside the evaporator Ps= 143.3 kPa Stream D = 3024 kg xp = 0 T = 373K Top Product P=101.32 kPa T = 373K Bottom Product kg B = 6048 h *8 = 0.015 T = 373K kg F = 9072 h xp = 0.01 T, = 311K Feed
