Acetylene Converter Simulation
The Acetylene Converter Reactor simulation is a rigorous and high-fidelity mathematical process model that provides a realistic dynamic response for an acetylene convertor reactor in an ethylene plant.
Process Overview:
Acetylene is produced as an impurity in the ethylene cracking heaters. The concentration of acetylene must be reduced to a few PPM (< 1 PPM) to produce a polymer-grade ethylene product. The simulated acetylene converter unit consists of a fixed bed catalytic reactor with three beds that performs selective hydrogenation of acetylene to ethylene.
