Modeling of Industrial High Pressure Autoclave

2001-1-13 · due to a higher cooling surface area than in the autoclave reactor. Since decomposition reactions occur over a very small time in-terval [Huffman et al., 1974] there is no practical way to control the high temperature and pressure in the reactor once the decom-position reactions have started. Thus, it is common for LDPE re-

Operation of High-pressure Reactor Vessels (Parr Reactor

High-pressure reactor vessels can maintain environments of 3,000 PSI and 500 degrees. Vessels rated for higher pressures require thicker walls, though, making temperature control more difficult. The manufacturer''s limits must be maintained during operation, as the gases are highly reactive, as well as the high pressure being a hazard itself.

Reactor Pressure Control Design - Chemical plant design

2014-7-7 · If the reactor is liquid full, controlling pressure in it will be a bear irrespective of the dissolved liquid. If the reactor has a gas headspace, which presumably would be the reason for desiring the pressure, you use a separator and control pressure on the gas and level via throttling liquid on the separator.
