September 8, 2017 Simulating a Divided Wall Column with CHEMCAD

ChemCad Simulation of Divided Wall Column Simulating a Divided Wall Column with various column configurations can be easily achieved when developed within ChemCad. Why would one consider a divided wall column in the first place? Divided wall columns offer savings in capital costs and operating costs but more specifically, energy costs! Traditionally, if you have […]

August 25, 2017 CHEMCAD Dynamics for Operator Training

CHEMCAD Dynamics is a remarkable tool for operator training. The example shown is a distillation column that looks like a Piping & Instrument Diagram. Each control loop can be modified by changing the proportion, integral and derivative values. The model responds similarly to a plant distillation column. Liquid holdup in the column, heat exchangers and […]

August 10, 2017 Eliminating Fouling Reboilers in Continuous and Batch Distillation

Continuous Distillation with a Fouling Reboiler A large chemical plant operates a fouling reboiler with forced circulation on a distillation column. When allowing boiling in the tubes, the operation suffers from severe fouling of the exchanger. Suppressing the evaporation in the tubes by installing a throttle plate in the reboiler outlet did not inhibit fouling.  The […]
