ABSTRACT:
In a hydrotreating process a two phase flow splitter is used in combination with parallel heat exchanger trains for heat transfer stability. Flow maldistribution of liquid and vapor between heat exchanger trains is thereby avoided without more complex feedback control. The two phase flow splitter is inherently phase volume ratio stable. Prior methods of flow splitting were only phase volume ratio metastable. Improved heat recovery at lower equipment cost is thereby achieved.
