VIS-SIM™ simulates visbreaker unit operation, performing detailed heat-balance, and pressure-drop calculations. It predicts the maximum conversion possible for the unit to produce stable fuel oil.

With VIS-SIM, you can identify potential performance improvements by monitoring daily operations and evaluating alternative unit operating strategies. VIS-SIM can be configured to most visbreaking process flow schemes. It contains a rigorous furnace model using the tube geometry and detailed fluid characterisation based on easily available plant data. VIS-SIM models either coil or soaker drum type units. The downstream product operation, including cutter streams, can be simulated fully with the Petro-SIM flowsheeting tools.

For specified feeds, operating conditions and constraints, VIS-SIM determines the resulting product yields and properties. Overall unit operating economics can be calculated based on feed and product values and operating costs.

VIS-SIM is available within Petro-SIM™ and Petro-SIM Express.
