WebHydrocarbon gas liquids (HGLs) are hydrocarbons that occur as gases at atmospheric pressure and as liquids under higher pressures. HGLs can also be liquefied by cooling. The specific pressures and temperatures at which the gases liquefy vary by the type of HGLs. HGLs may be described as being light or heavy according to the number of carbon ... WebCommonly used moderators include regular (light) water (roughly 75% of the world’s reactors), solid graphite (20% of reactors), and heavy water (5% of reactors). In most nuclear reactors, water is both a coolant and a moderator. The moderation occurs especially on hydrogen nuclei. In the case of the hydrogen (A = 1) as the target nucleus, the ...

WebApr 21, 2024 · Heavy oils are used to make industrial products like asphalt and plastics. Medium oils have sulfur content that falls somewhere between heavy and light. Light oils are generally used in diesel, gasoline, and aviation fuel because they take less processing.
The physical properties of water and heavy water differ in several respects. Heavy water is less dissociated than light water at given temperature, and the true concentration of D ions is less than H ions would be for a light water sample at the same temperature. The same is true of OD vs. OH ions. For heavy … See more Heavy water (deuterium oxide, H 2O, D 2O) is a form of water that contains only deuterium ( H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope ( H or H, also called protium) that makes … See more Semiheavy water Semiheavy water, HDO, exists whenever there is water with light hydrogen (protium, H) and deuterium (D or H) in the mix.
