Thought question 16: Which gases are referred to as liquefied gases in classification?
Liquid nitrogen, liquid oxygen, liquid argon, liquid hydrogen, liquid helium, liquid ethylene, liquid carbon dioxide, LNG, liquid NO2, etc
A gas that is in a gaseous state at normal temperature and pressure, and must be pressurized to be liquefied
Liquid nitrogen, liquid oxygen, liquid argon, liquid hydrogen, liquid helium, liquid ethylene, liquid carbon dioxide, LNG, liquid NO2, etc
In my opinion, it refers to the physical properties of a gaseous medium; such media have different dew points at various temperatures and pressures. As long as dew point formation or liquefaction occurs during the operation of the equipment, that equipment should be classified accordingly. According to the standards, a liquefiable gas is a gas that remains in gaseous state at normal temperature and pressure, but undergoes liquefaction or exists in liquid form within a certain process
All gases can be liquefied. Liquefied gases refer to those in which the gas is in a liquid state under the operating conditions of your equipment; such substances are classified as belonging to Group 1
