低温常压条件下水合物法储存甲烷的实验研究

利用水合物法实现对天然气的工业储运,需要提高水合物的储气量并解决水合物的分解速度问题。为此,文章研究了在十二烷基硫酸钠（SDS）体系中,甲烷水合物的储气量和在冰点以下的常压分解规律。研究发现,SDS浓度为650 mg/L时甲烷水合物储气量达到最高值,约为170 V/V。分解温度为268.2~272.2 K区域内,甲烷水合物的分解速率随温度的降低而降低;在268.2 K时,甲烷水合物分解速率最低。

Study on CH4 Storage by Hydrate Technology under Atmospheric Pressure and Temperatures below Ice Point

To commercially store and transport natural gas by gas hydrate,it was necessary to improve the gas-storing capacity and the decomposition velocity of the hydrate.Therefore,the gas-storing capacity and the decomposition law of methane hydrate under the atmospheric pressure were studied in the system of SDS.It was found that gas-storing capacity of methane was 170 V/V with SDS concentration of 650 mg/L.It was also found that the dissociation rate of methane hydrate decreased with the temperature(ranging from ...
