A new type of dehydration unit of natural gas and its design considerations

摘要

A new type of dehydration unit for natural gas is described and its basic structure and working principles are presented.The key factors affecting the performance and dehydration efficiency of the unit such as nucleation rate, droplet growth rate, the strength of the swirl, and the position at which the shock wave occurs are discussed. And accordingly the design considerations of each component of the unit are provided. Experimental investigations on the working performance of the unit justified the design considerations.
