This paper will discuss and compare the methods used to suppress hydrate formation in natural gas streams. Included in the comparison will be regenerated systems using ethylene glycol and non-regenerated systems using methanol. A comparison will be made between the quantities of methanol and ethylene glycol required to achieve a given suppression. A discussion of BTEX emissions resulting from the ethylene glycol regenerator along with the effect of process variables on these emissions is also given.
