Pressure losses in the natural gas coolers caused by deposits on the heat transfer surfaces

Abstract

Analysed is the effect of the deposits formed on the inside and outside heat transfer surfaces of the natural gas coolers on the pressure losses. Sediments on both sides of the heat transfer surface represent the hydraulic resistance, overcoming of which, for the given degree of gas cooling, requires to increase the compression power and to exploit the higher volume of the cooling air. Operation of the cooler with the clean surface enables to save not negligible amount of the electrical power.
