2019 Philadelphia Refinery Explosion
In the early morning of June 21, 2019, a fire and multiple explosions occurred at the Philadelphia Energy Solutions (PES) refinery in Philadelphia, Pennsylvania. A release of hydrocarbons and hydrofluoric acid in the refinery's alkylation unit caused a ground-hugging vapor cloud which rapidly ignited, leading to three separate explosions minutes apart from each other. The largest explosion, a BLEVE, sent a vessel fragment flying across the Schuylkill River. Five employees sustained minor injuries, but there were ultimately no fatalities. The refinery announced it would shut down operations the same month, and filed for bankruptcy a month later. Background The Philadelphia Energy Solutions refinery was an oil refinery complex in Philadelphia, Pennsylvania. It was first used in 1866 by the Atlantic Petroleum Storage Company, who built the complex to store and transport petroleum and its byproducts. By 1870, the company had become Philadelphia's largest employer and a leader in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasoline
Gasoline ( North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical st ...

Elbow Pipe
A fitting or adapter is used in pipe systems to connect sections of pipe (designated by nominal size, with greater tolerances of variance) or tube (designated by actual size, with lower tolerance for variance), adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in plumbing to manipulate the conveyance of fluids such as water for potatory, irrigational, sanitary, and refrigerative purposes, gas, petroleum, liquid waste, or any other liquid or gaseous substances required in domestic or commercial environments, within a system of pipes or tubes, connected by various methods, as dictated by the material of which these are made, the material being conveyed, and the particular environmental context in which they will be used, such as soldering, mortaring, caulking, plastic welding, welding, friction fittings, threaded fittings, and compression fittings. Fittings allow multiple pipes to be conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elbow Pipe From Pes Explosion
The elbow is the region between the arm, upper arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the Lateral epicondyle of the humerus, lateral and the Medial epicondyle of the humerus, medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm; more specifically between the humerus in the upper arm and the radius (bone), radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body. The term ''elbow'' is specifically used for primate, humans and other primates, and in other vertebrates it is not used. In those cases, forelimb plus joint is used. The name for the elbow in Latin is ''cubitus'', and so the word cubital is used in some elbow-related terms, as in ''cubital nodes'' for example. Structure Joint The elbow joint has three different portions surrounded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
