Abstract:An in-house designed
membrane process suitable for subsea natural
gas dehydration was studied. The use of a membrane absorber together
with a thermopervaporation (TPV) unit for solvent regeneration in
a closed loop enables the effective and clean production of high-pressure
natural gas close to the wellhead. This process avoids the continuous
chemical injection for preventing hydrate formation in natural gas
pipelines. The regeneration of the absorbent agent (triethylene glycol
(TEG)) by TPV in the closed loop… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
