Study on Temperature Characteristics of Hydrate Slurry during Cyclopentane-Methane Hydrate Formation
In this work, the temperature characteristics of hydrate slurry related to transition heat in the cyclopentane (CP)/methane (CH4) hydrate formation process were systematically investigated. A crystallizer with a special heat-insulating layer of aerogel was designed to hold the transition heat, and t...
