Flash Drum Trainer with PLC

Model Series: FD-700

Description: The flash drum trainer is a bench-scale plant that demonstrates continuous separation of a binary mixture of water saturated with carbon dioxide. The process has instrumentation to provide for control of operating flow, temperature, level and pressure. This trainer provides the student the opportunity to gain real operating experience focusing on both the process of flash separation and control strategy.

Function: The separation of volatile gasses dissolved in a liquid and recovery of the components usually involves a flash drum. Flash drum operations are found throughout the petroleum, petrochemical and numerous other industries. This trainer separates a water/CO2 mixture in a see-through, industrial glass vessel. The trainer is equipped with process measurement and control devices. It has one each of: temperature, pressure, level and flow controls. The entire trainer is controlled from a programmable logic controller computer interface (PLC).
