Large pressure depression of methane hydrate by adding 1,1-dimethylcyclohexane

Hara T, Hashimoto S, Sugahara T, Ohgaki K

The structure-H hydrate of 1,1-dimethylcyclohexane (DMCH) helped by methane has been investigated in a temperature range of 274.6-289.3 K and pressure range up to 6.7 MPa. The present results suggest that 1, 1-DMCH is a suitable additive which makes a mild-pressure handling of natural-gas hydrate possible. (c) 2005 Elsevier Ltd. All rights reserved.
