Formation characteristics of methane hydrate in a micro-bubbler
摘要
Abstract
Effects of gas flow rates,pressures,temperatures and filter meshes in a high pressure bubbler on the formation kinetics and forms of methane gas hydrate in pure aquatic system are investigated. According to the experiment results,increasing the gas flow rate and pressure and decreasing the temperature can enhance methane hydrate formation rates. However,with the increase of the gas flow rate,gas conversion is reduced. Adding filter meshes may obviously enhance the hydrate formation rate and gas conversion and an optimum specification of filter mesh is 200. Such results also indicate that,it's very easy for methane hydrate to produce on the gas-liquid interface to result in formation of hydrate bubbles,and that the gas flow rate imposes a remarkable impact on the hydrate forms. When the gas flow rates is low,hydrate bubbles can keep their shape and are not easy to break,and they gather together with a loose texture,and conversely,gas is easy to escape when the gas flow rate is enhanced,and hydrate bubbles are easy to deform and break and aggregate with a relatively compact texture. Pressures and temperatures impose little effects on hydrate forms. Adding filter meshes can obviously decrease the gas bubble volume and more hydrate bubbles are formed.关键词
