Other AbstractThe system temperature change and heat loss in the process of cyclopentane-methane binary hydrates formation in the system containing brine at 4.0℃ and 8.5MPa were investigated. The values of the maximum temperature (Tmax were measured under different conditions, including gas/liquid volume ratio (Rgl, cyclopentane/water volume ratio (rv and salinities of the solutions (wNaCl. The experimental results show that rv and WNaCl have a significant influence on Tmax while Ro has a little effect on Tmax. The optimum Ro and rv are 0.786 and 0.556, respectively. Under the optimized conditions, the values of Tmax are 21.3℃, 12.6℃, 11.5℃ and 10.7℃ obtained in the brine system with WnaCl of 0, 3.5%, 6.0% and 7.0%, respectively. In addition, the heat analysis indicates that the major heat is consumed via heat radiating from the inner reactor to the outside cold environment. Therefore, accelerating the formation rate of hydrates in the reactor and improving the insulation properties of insulating layer are helpful to enhance the heat efficiency and Tmax in the process of the cyclopentane-methane binary hydrates formation.
