Description

Double-sided visible hydrate reaction kettle

Technical Field

The utility model relates to a non renewable energy's exploitation laboratory glassware especially designs a two-sided visual hydrate reation kettle.

Background

Natural gas is a generic term for hydrocarbon-based gas mixtures present in subterranean rock reservoirs, has a specific gravity of about 0.65, is lighter than air, and has the characteristics of being colorless, odorless, and non-toxic.

Abundant natural gas resources are stored in the ocean, wherein the combustible ice is solid natural gas, and the natural gas exists in the form of the solid combustible ice in the high-pressure and sunshine-free low-temperature environment of the seabed.

Natural gas is mainly composed of alkanes, most of which are methane, with small amounts of ethane, propane and butane, and generally contains hydrogen sulfide, carbon dioxide, nitrogen and moisture, and small amounts of carbon monoxide and trace amounts of noble gases such as helium and argon. To aid in leak detection, mercaptans, tetrahydrothiophenes, and the like are also used to odorize the natural gas before it is sent to the end user.

The technicians cannot get intuitive knowledge of the various physicochemical properties of the solid and gaseous nature of natural gas. Therefore, careful research needs to be performed on various problems, such as: the solid combustible ice of natural gas is synthesized under the conditions of what pressure and what temperature. Solid combustible ice decomposes at pressures below and temperatures above. At present, no instrument for visually researching various parameters of the solid state precipitation of the combustible ice exists.
