Title:
NATURAL GAS DIFFUSION COEFFICIENT MEASUREMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/128706
Kind Code:
A1
Abstract:
Provided is a natural gas diffusion coefficient measurement apparatus, which is a gas parameter measurement apparatus, comprising a core chamber and two sampling and detecting apparatuses arranged on the two sides of the core chamber, respectively; also comprising two pressure supply apparatuses arranged on the two sides of the core, respectively; a pressure supply apparatus comprises intermediate containers and an air source, and a synchronous pressurizing component which simultaneously increases the pressure of the two intermediate containers. After the initial pressure in the intermediate container is adjusted so as to be consistent, the amount of added pressure is also the same, ensuring that the air pressure on both sides of the core is the same. Thus the problem of the prior art of excessive pressure difference in the measurement process is solved.
