What gases are greenhouse gases? – Jean-Marc Jancovici
1/8/2007· Breakdown of the “natural” greenhouse effect by contributing gas. As halocarbons are industrial gases they are not represented here. The relative importance of each gaz has not varied much today. But if we only consider the greenhouse effect of human origin, sometimes called “additional” greenhouse effect (because it goes on top of the natural one), or anthropic greenhouse effect, the

halogen | Facts, Definition, Properties, & Uses | Britannica
Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar properties, of which

Fluorine Speeds up Two-Dimensional Materials Growth
As the fluorine released from the metal fluoride surface easily reacts with methane gas, there will be a sufficient amount of CH 3 F or CH 2 F 2 molecules in the gap between Cu and BaF 2 substrates. These molecules could decompose on a Cu surface much more easily than CH4 does.

» Processing Natural Gas NaturalGas
This means that, when in contact with a stream of natural gas that contains water, glycol will serve to ‘steal’ the water out of the gas stream. Essentially, glycol dehydration involves using a glycol solution, usually either diethylene glycol (DEG) or triethylene glycol (TEG), which is brought into contact with the wet gas stream in what is called the ‘contactor’.
