Investigation on gas hydrates formation and dissociation in multiphase gas dominant transmission pipelines
In this work, a gas hydrate formation and dissociation study was performed on two multiphase pipeline systems containing gasoline, CO2, water, and crude oil, CO2, water, in the pressure range of 2.5-3.5 MPa with fixed water cut as 15 using gas hydrate rocking cell equipment. The system has 10, 15 an...
