Propane is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is often a constituent of liquefied petroleum gas (LPG), which is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation; other constituents of LPG may include propylene, butane, butylene, butadiene, and isobutylene. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane has lower volumetric energy density than gasoline or coal, but has higher gravimetric energy density than them and burns more cleanly.
A pipeline is a system of pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than 2,175,000 miles (3,500,000 km) of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. The main attribute to pollution from pipelines is caused by corrosion and leakage.
Hess Corporation is an American global independent energy company involved in the exploration and production of crude oil and natural gas. It was formed by the merger of Hess Oil and Chemical and Amerada Petroleum in 1968. Leon Hess was CEO from the early 1960s through 1995, after which his son John B Hess succeeded him as chairman and CEO. The company agreed to be acquired by rival oil company Chevron in October 2023.
The economic effects of Hurricane Katrina, which hit Louisiana, Florida, Texas and Mississippi in late August 2005, were far-reaching.
The Colonial Pipeline is the largest pipeline system for refined oil products in the U.S. The pipeline – consisting of three tubes – is 5,500 miles (8,850 km) long and can carry 3 million barrels of fuel per day between Texas and New York.
The Refugio oil spill on May 19, 2015, contaminated one of the most biologically diverse areas of the West Coast of the United States with 142,800 U.S. gallons of crude oil. The corroded pipeline that caused the spill closed indefinitely, resulting in financial impacts to the county estimated as high as $74 million as it and a related pipeline remained out of service for three years. The cost of the cleanup was estimated by the company to be $96 million with overall expenses including expected legal claims and potential settlements to be around $257 million.
On Monday, September 12, 2016, a leak in the Colonial Pipeline in Shelby County, Alabama, spilled an estimated 350,000 US gallons of summer-grade gasoline, requiring a partial shutdown of the pipeline, and causing gas shortages in much of the Southeastern United States. Six states are affected, with Alabama, Tennessee, Georgia and Virginia declaring states of emergency. The same line suffered an explosion in late October at a site only miles distant.
On 18 January 2019, a pipeline transporting gasoline exploded in the town of Tlahuelilpan, in the Mexican state of Hidalgo. The blast killed at least 137 people and injured dozens more. Mexican authorities blamed fuel thieves, who had illegally tapped the pipeline. The explosion was particularly deadly because large crowds of people had gathered at the scene to steal fuel. Security forces tried to persuade people to move away from the scene, but they were outnumbered and asked not to engage with civilians for fear of causing a violent confrontation. The leak was reported at 17:04 CST (23:04 UTC), and the explosion occurred two hours later at 19:10. It took about four hours for responders to extinguish the fire.
On May 7, 2021, Colonial Pipeline, an American oil pipeline system that originates in Houston, Texas, and carries gasoline and jet fuel mainly to the Southeastern United States, suffered a ransomware cyberattack that afflicted computerized equipment managing the pipeline. The Colonial Pipeline Company halted all pipeline operations to contain the attack. Overseen by the FBI, the company paid the amount that was asked by the hacker group within several hours; upon receipt of the ransom, an IT tool was provided to the Colonial Pipeline Company by DarkSide to restore the system. However, the tool required a very long processing time to restore the system to a working state.
A major oil spill from the Colonial Pipeline in a nature reserve near Huntersville, North Carolina, United States, began on July 27, 2020. The spill resulted in approximately 2,000,000 U.S. gallons (7,600,000 L) of gasoline discharge and led to a cleanup effort that is still ongoing and expected to continue for several years. Several sources have noted that the spill is one of the largest in the history of the United States, with EnergyWire calling it "the largest U.S. gasoline pipeline spill on record".
