To represent the kinetics of ethylene polymerization a general reaction …

Reactor Pressure Control Design - Chemical plant design …

2014-7-7 · cheme. One way of holding back pressure on a reactor is a simple back pressure regulator. That works if your outflows are only gas and you are not entraining any solids or liquid slugs. Another way to do it is a control valve and a pressure transducer. The advantage of the control valve is that you can handle more solids or liquids entrainment.
