The MTBE controversy concerns methyl tert-butyl ether (MTBE), a gasoline additive that replaced tetraethyllead.MTBE is an oxygenate and raises gasoline's octane number.Its use declined in the United States in response to environmental and health concerns.
Premium gas must be at least 93 octane if it contains 10% or more of ethanol Maryland: 87 89 93 Massachusetts: 87 89 93 Michigan: 87 89 93 85 and 86 octane may be sold if labeled as subregular [6] Minnesota: 87 89 91 110 octane fuel may be available at certain locations in southern parts of the state. Mississippi: 87 89 93 Missouri: 87 89 91/93
This way performance is kept at its optimum while mostly eliminating the risk of engine damage caused by knock (e.g. when running on low octane fuel). [5] An early example of this is in turbocharged Saab H engines , where a system called Automatic Performance Control was used to reduce boost pressure if it caused the engine to knock.
July 29 - Crews repairing a leaking liquid fuel pipeline near Arkansas City, Kansas accidentally ignited residual fuel in the area, causing a fire that burned 3 of the crew. [129] August 22 – Crews working on an extension of Plantation Pipeline in Ferry Farms, Virginia hit a natural gas pipeline. Gas escaped for over three hours before it was ...
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
Fuel additives in the United States are regulated under section 211 of the Clean Air Act (as amended in January 1995). The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives.
The fuel-characteristics of a particular gasoline-blend, which will resist igniting too early are measured as the octane rating of the fuel blend. Gasoline blends with stable octane ratings are produced in several fuel-grades for various types of motors. A low octane rated fuel may cause engine knocking and reduced efficiency in reciprocating ...
An attack with seven high expansion and five low expansion foam generators produced more than 4 million cubic feet of foam. These efforts failed, however, and a controlled burnout had to be accepted. [12] 1969 – The 1969 Santa Barbara oil spill. In January and February 1969, in the Santa Barbara Channel, near the city of Santa Barbara, in ...
