Nitrous oxide from. The fluorinated gas production source category consists of processes that manufacture a fluorinated gas from any raw material or feedstock chemical, except for processes that generate HFC-23 during the production of HCFC-22. Fluorinated Gas emissions are all caused by human activity. HFCs are the largest source of fluorinated gas emissions. What do fluorinated gases come from? . industrial/manufacturing processes), i.e. Refrigerants used by businesses and residences emit fluorinated gases. Extraction of fluoroalkyl sources, including trifluoromethyl and difluoromethyl groups, from the fluorinated gases is highly desirable, yet challenging under regular batch reaction conditions. These gases (e.g., CO 2, H 2 O, NO, CFCs, CO) are very good at absorbing and re-emitting infrared radiation. These gases can be found in different products such as fridges or aerosol cans.

Alternatives to fluorinated gases. HFCs are primarily used as refrigerants, foam-blowing agents, aerosol propellants, solvents and fire suppressants. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb fluo meaning 'flow' gave the mineral its name. Fluorinated gases ('F-gases') are a family of man-made gases used in a range of industrial applications.. Where are these gases coming from?
