Flow loops for hydrate formation kinetics

Results obtained in the Texaco flow loop (1.93 in. or 4.9 cm ID, 14 m in length, rated to 13.8 MPa) and in field tests at Werner-Bolley, Southern Wyoming 

Herri and coworkers (Fidel-Dufour et al., 2005) have developed a flow loop reactor (in Saint Etienne, France) operating at pressures of 1-10 MPa at 0-10°C. The flow section is 36.1 m long, 1.0 cm internal diameter, and has a constant slope of 4°. The unique feature of this flow loop is that the exit of the flow section is connected to a gas lift riser (10.6 m long and 1.7 cm internal diameter) in which gas coming from a separator located at the top of the column is re-injected. The gas lift is thereby able to move an emulsion or suspension slurry without any pump or mechanical system.
