gas transmission rate
1Oxygen transmission rate — (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non porous materials, where the mode of transport is diffusion, but there are a growing number of applications… …
2Moisture vapor transmission rate — (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. There are many industries where moisture control is critical. Moisture sensitive foods and pharmeceuticals are put in packaging… …
3Carbon dioxide transmission rate — (COTR) is the measurement of the amount of carbon dioxide gas that passes through a substance over a given period. It is mostly carried out on non porous materials, where the mode of transport is diffusion, but there are a growing number of… …
4Gas throttling — is reduction of pressure in a gas flow forced through a throttle – local hydrodynamic resistance point (orifice choke, valve, tap, check), accompanied by temperature change. Gas throttling is used for liquefying and deep refrigeration of gases.… …

9History of the petroleum industry in Canada (natural gas) — Natural gas has been used almost as long as crude oil in Canada, but its commercial development was not as rapid. This is because of special properties of this energy commodity: it is a gas, and it frequently contains impurities. The technical… …
10natural gas — a combustible mixture of gaseous hydrocarbons that accumulates in porous sedimentary rocks, esp. those yielding petroleum, consisting usually of over 80 percent methane together with minor amounts of ethane, propane, butane, nitrogen, and,… …
