水化物是一种固体物质,当液态水和天然气在压力下混合时,就会形成水化物。水化物沉积在管道和设备内,会造成堵塞和压力下降。脱除液态水、注甲醇、提高温度和降低压力是清除和防止管道系统生成水化物的方法。对储存在大气压力和冰点以下的天然气水化物的稳定性进行了试验研究,天然气水化物可在压力为2～6MPa和温度为0～20°C的搅拌器中生成,水化物冷冻和储存在温度为-5°C、-10°C和-18°C的深冷器中,如果在常压下保持冷冻,天然气水化物在10d内保持稳定。
Hydration is a solid material that forms hydrates when liquid water and natural gas are mixed under pressure. Hydrate deposits in pipes and equipment can cause clogging and pressure drops. Removal of liquid water, methanol injection, increase the temperature and reduce the pressure is to eliminate and prevent hydration of pipe systems. Experimental studies on the stability of natural gas hydrates stored below atmospheric pressure and freezing point were performed. Natural gas hydrates were generated in a mixer at pressures of 2 to 6 MPa and at temperatures of 0 to 20 ° C. The hydrates were frozen and stored In cryostats at temperatures of -5 ° C, -10 ° C and -18 ° C, the gas hydrate remains stable for 10 days if kept frozen at atmospheric pressure.
