Process Condenser Applications
Crude oil vacuum distillation
|
|
Refinery vacuum installation processes may elect to use a process condenser ahead
of an ejector system. This will depend on the operating pressure of the process and the volatility of the
overhead process vapors. |
|
Graham has proven installation experience and has provided numerous systems throughout
the world where vacuum condensation ahead of an ejector system is used. The overhead load from a
distillation vessel is a mixture of complex hydrocarbons, steam, and a large volume of noncondensible gases.
The application is sophisticated due to the complex vapor-liquid equilibrium calculations and the design of the
process condenser must minimize pressure drop. By keeping pressure drop to a minimum, condensation efficiency
is maximized and the size and operating cost of the energy-intensive ejector system are kept to a minimum.
