The chief use of ethane is the production of ethylene (ethene) by steam cracking. Steam cracking of ethane is fairly selective for ethylene, while the steam cracking of heavier hydrocarbons yields a product mixture poorer in ethylene and richer in heavier alkenes (olefins), such as propene (propylene) and butadiene, and in aromatic hydrocarbons.
Bubbles of methane, created by methanogens, that are present in the marsh, more commonly known as marsh gas. Marsh gas, also known as swamp gas or bog gas, is a mixture primarily of methane and smaller amounts of hydrogen sulfide, carbon dioxide, and trace phosphine that is produced naturally within some geographical marshes, swamps, and bogs.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

The annual ethane emission increase rate in North America between 2009 and 2014 was 3-5%. [18] It has been suggested that 62% of atmospheric ethane originates from leaks associated with natural gas production and transportation operations. [ 20 ]
Once produced, methane can reach the atmosphere via three main pathways: molecular diffusion, transport through plant aerenchyma, and ebullition. Primary productivity fuels methane emissions both directly and indirectly because plants not only provide much of the carbon needed for methane producing processes in wetlands but can affect its ...
Water transportation is the international movement of water over large distances. Methods of transportation fall into three categories: Aqueducts, which include pipelines, canals, tunnels and bridges; Container shipment, which includes transport by tank truck, tank car, and tank ship.
Syngas is often considered to be a petrochemical; although its production is a core industrial gases technology. Similarly, projects harnessing Landfill gas or biogas, Waste-to-energy schemes, as well as Hydrogen Production all exhibit overlapping technologies. Helium is an industrial gas, even though its source is from natural gas processing.
Environmental psychology is a branch of psychology that explores the relationship between humans and the external world. [1] It examines the way in which the natural environment and our built environments shape us as individuals.
