Both steam cracking and production from natural gas via ethane are estimated to emit 1.8 to 2kg of CO2 per kg ethylene produced, [54] totalling over 260 million tonnes a year. [55] This is more than all other manufactured chemicals except cement and ammonia. [ 56 ]

The term "fine chemicals" was in use as early as 1908. [1] The emergence of the fine chemical industry as a distinct entity dates to the late 1970s, when the overwhelming success of the histamine H 2 receptor antagonists Tagamet (cimetidine) and Zantac (ranitidine hydrochloride) created a strong demand for advanced organic chemicals used in their manufacture.
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.
Under the new pricing plan, a month’s supply of the lowest dose, 2.5 milligrams, will cost $399, while a month’s supply of the 5 mg dose will cost $549.
In all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.
