Study of Inert Current System Designed for Pressure Control of Micro-Positive Pressure Distillation

Abstract:

Micro-positive pressure distillation is commonly used in processes where the feed stock or products are oxygen sensitive. Constant column pressure is critical for such process as pressure fluctuations may change column performance and the oxygen-free environment leading to dramatic change in product quality. In this paper, an inert current system designed for micro-positive pressure distillation is introduced. Details of both the operation principle and system features including response time and pressure deviation are studied. Four mathematical equations describing the features are put forward to help select the appropriate parameter. This system is promising for its high sensitivity and simple construction.
