ABSTRACT:
A vacuum distillation system and method utilizing a low capacity vacuum producing ejector operated in parallel with a primary ejector during the Winter months enables significant reduction in the absolute pressure of a vacuum distillation column. Operation of a vacuum distillation tower at lower absolute pressures results in increased yield of desirable vacuum distillation products.
