The 1979 IUPAC nomenclature rules made an exception for retaining the non-systematic name ethylene; [48] however, this decision was reversed in the 1993 rules, [49] and it remains unchanged in the newest 2013 recommendations, [50] so the IUPAC name is now ethene. In the IUPAC system, the name ethylene is reserved for the divalent group -CH 2 CH 2-.
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
An ethylene plant, once running, does not need to import steam to drive its steam turbines. A typical world scale ethylene plant (about 1.5 billion pounds (680 KTA) of ethylene per year) uses a 45,000 horsepower (34,000 kW) cracked gas compressor, a 30,000 hp (22,000 kW) propylene compressor, and a 15,000 hp (11,000 kW) ethylene compressor.

The Shell higher olefin process (SHOP) is a chemical process for the production of linear alpha olefins via ethylene oligomerization and olefin metathesis invented and exploited by Shell plc. [1] The olefin products are converted to fatty aldehydes and then to fatty alcohols , which are precursors to plasticizers and detergents .
Trinidad and Tobago is the world's largest methanol producer, with exports mainly to the United States. [18] The feedstock for the production of methanol comes natural gas. The conventional route to methanol from methane passes through syngas generation by steam reforming combined (or not) with partial oxidation. Alternative ways to convert ...
