Abstract

The invention discloses a gas-solid-liquid three-phase separation device and method for natural gas hydrate. The device includes a support, a liquid level transmitter, a separation cylinder installed on the support, and a separation cylinder connected to the lower end of the separation cylinder. Settling cylinder, the separation cylinder has a hollow cavity, the upper end of the separation cylinder is closed and a gas discharge interface is provided, the gas inlet of the gas discharge interface is provided with a filter screen, and the gas discharge interface is used to discharge gas, solid and liquid For the gas after phase separation, the hollow cavity of the separation cylinder is provided with a drainage interface; the settling cylinder has a hollow cavity, and the hollow cavity of the settling cylinder and the hollow cavity of the separation cylinder pass through a microporous metal filter The pipe is connected, and the method is carried out by using the gas-solid-liquid three-phase separation device for natural gas hydrate as described above. The invention realizes the separation of the liquid-solid three-phase flow of gas produced in the simulated natural gas hydrate exploitation, and the device is easy to disassemble and clean, and can be recycled.

Description

technical field [0001] The invention relates to the technical field of multiphase separation of natural gas hydrate simulated mining, in particular to a gas-solid-liquid three-phase separation device and method for natural gas hydrate. Background technique [0002] At present, natural gas hydrate has been successfully tested, but there are still many problems to be solved before commercialization. Therefore, simulated production is still the main research method in the research of natural gas hydrate production, and the separation and measurement of gas-liquid-solid three-phase flow in the process of simulated production is an important index of research. [0003] The existing scheme cannot separate and collect the gas-produced liquid and solid in real time, and there is no solid-liquid phase grit chamber to collect the sand in real time. The device is inconvenient to clean, or even impossible to clean, resulting in errors in the experiment. Contents of the invention [0...
