Studies on temperature characteristics and initial formation interface during cyclopentane-methane hydrate formation in large-scale equipment with bubbling

摘要: Abstract In this work, temperature characteristics during hydrate formation were investigated in the cyclopentane-methane system using large-scale equipment with bubbling. The volume each experiment was increased by a factor of 80 compared previous work. A group scaled-up experiments, under optimal condition based on experiments smaller crystallizer, carried out to verify scale-up potential hydrate-based thermal fluid production process. Another performed different variables (volume ratio cyclopentane water, gas/liquid and pressure) figure initial interface optimize fluid. Experimental results illustrate that process can be scaled up 80, however, needs optimized adjusting accordingly. Moreover, liquid cyclopentane/water more than affects accumulation. particular, initially occurs water side near interface. large amount accumulates bulk phase, forming new interfaces. Thermal specific range produced heat released conducted from
