Hydrate Microscopic Observation System

Abstract

The invention relates to the technical field of hydrates, in particular to a microscopic observation system of hydrates. The microscopic observation system includes a high-pressure reaction module (34), a fluid delivery module (33), a control module (35) and a microscopic observation module (11). The delivery module is set to be able to form a one-way circulation loop between the high-pressure reaction module and the microscopic observation module so that the hydrate flows into the sample chamber of the sample observation device through the liquid inlet and then flows out through the liquid outlet. A control unit (14) for the reaction conditions of the reaction module, the temperature of the hydrate delivered by the fluid delivery module, and the temperature of the hydrate flowing through the sample chamber in the microscopic observation module. The microscopic observation system can observe the growth and accumulation of hydrates in different solutions under different temperature and pressure conditions from a microscopic point of view, which improves the detection accuracy of hydrate phase balance.

Description

technical field [0001] The invention relates to the technical field of hydrates, in particular to a microscopic observation system of hydrates. Background technique [0002] Natural gas hydrate (Gas Hydrate), commonly known as "combustible ice", is an ice-like crystal formed by gas molecules and water molecules. The guest is enclosed in a cage, and each cage can contain only one guest molecule. Through the interaction between the host and the guest, the hydrate forms a stable structure. In nature, natural gas hydrate mainly occurs in seabed sediments and permafrost, and its main component is methane, and 1 cubic meter of natural gas hydrate can decompose about 164 cubic meters of natural gas at normal temperature and pressure. Therefore, Under the same conditions, the energy generated by the combustion of "combustible ice" is dozens of times higher than that of other fossil fuels, and it is green and clean, which has great development value. [0003] Since natural gas hydr...

Problems solved by technology

[0006] The purpose of the present invention is to provide a microscopic observation system for hydrates in order to overcome the problem of low phase balance detection accuracy caused by directly observing the microscopic morphology of hydrates in the reaction device in the prior art. The microscopic observation system includes a sample observation device independent of the high-pressure reaction module, which can provide an observation place for hydrate independent of the high-pressure reaction module (the reaction place of the hydrate), thereby improving the detection accuracy of the hydrate phase balance
