Petroleum piping

Petroleum pipe hues before 1969 were built to ASA (now ANSI) Standard B31.4 for liquids and Standard B31.8 for gas. These standards were seldom mandatoiy because few states adopted them. The U.S. Department of Transportation (DOT), which now has responsi-bihty for pipe-line regulation, issued Title 49, Part 192—Transportation of Natural Gas and Other Gas by Pipeline Minimum Safety Standards, and Part 195—Transportation of Liquids by Pipehne. These contain considerable material from B31.4 and B31.8. They allow generally higher stresses than the ASME Pressure Vessel Code would allow for steels of comparable strength. The enforcement of their regulations is presently left to the states and is therefore somewhat uncertain. [Pg.1020]

Many piping specifications are partially established by consensus standards such as the American National Standards Institute (ANSI), ANSI B31.3, Chemical Plant and Petroleum Piping Code, the American Petroleum Institute s (API) API 5L Specifications for Lined Pipe, or the National Fire Protection Association s (NFPA) NFPA 30 Flammable and Combustible Liquids Code. These can form the foundation for specifications however, individual plant operating conditions and history should be considered when establishing piping specifications. ... [Pg.1489]

Corrosion inhibitors prevent the oxidation of the metal pieces in diesel engines. Since most petroleum pipes and tanks are made of steel, the most common corrosion is the formation of rust in the presence of water. The fuel is thus contaminated with rust particles, and these can plug fuel filters as well as increase fuel pump and injector wear. Corrosion inhibitors attach to metal surfaces and form a film that prevents attack by corrosive agents. They typically are used in concentrations of up to 15 ppm. [Pg.54]

The term highly hazardous chemical is also defined by the American Society of Mechanical Engineers in ASME B31.3—1990 Chemical Plant Petroleum Piping. They define a Category M Huid Service as that service in which the potential for personnel exposure is judged to be significant and in which a single exposure to a very small quantity of a toxic fluid can produce serious, irreversible harm to persons even when prompt restorative measures are taken. [Pg.94]

The presence of these acids in crude oils and petroleum cuts causes problems for the refiner because they form stable emulsions with caustic solutions during desalting or in lubricating oil production very corrosive at high temperatures (350-400°C), they attack ordinary carbon steel, which necessitates the use of alloy piping materials. [Pg.331]

If possible, this can be done by building a 1 1 mock-up of the measuring position, using the same pipe dimensions and material as in the process part. The mock-up should then be filled with a suitable liquid, in this case gasoline or light petroleum, to which a precisely measured amount of tracer is added. This way, the response towards a known dilution of the tracer can be found. [Pg.1056]

Chemical-Process Vessels. Explosion-bonded products are used in the manufacture of process equipment for the chemical, petrochemical, and petroleum industries where the corrosion resistance of an expensive metal is combined with the strength and economy of another metal. AppHcations include explosion cladding of titanium tubesheet to Monel, hot fabrication of an explosion clad to form an elbow for pipes in nuclear power plants, and explosion cladding titanium and steel for use in a vessel intended for terephthaHc acid manufacture. [Pg.150]

One of the most efficient implementations of the slurry process was developed by Phillips Petroleum Company in 1961 (Eig. 5). Nearly one-third of all HDPE produced in the 1990s is by this process. The reactor consists of a folded loop with four long (- 50 m) vertical mns of a pipe (0.5—1.0 m dia) coimected by short horizontal lengths (around 5 m) (58—60). The entire length of the loop is jacketed for cooling. A slurry of HDPE and catalyst particles in a light solvent (isobutane or isopentane) circulates by a pump at a velocity of 5—12 m/s. This rapid circulation ensures a turbulent flow, removes the heat of polymeriza tion, and prevents polymer deposition on the reactor walls. [Pg.384]

Phillips Petroleum Company developed an efficient slurry process used for the production of both HDPE and LLDPE (Eig. 6). The reactor is built as a large folder loop containing long mns of pipe from 0.5 to 1 m ia diameter coimected by short horizontal stretches of pipe. The reactor is filled with a light solvent (usually isobutane) which circulates through the loop at high speed. A mixed stream containing ethylene and comonomers (1-butene,... [Pg.401]

Distillation. This is the point at which refining begins and was the first method by which petroleum was refined. Originally, distillation (qv) involved a batch operation in which the stiU was a cast-iron vessel mounted on brickwork over a fire and the volatile materials were passed through a pipe or gooseneck which led from the top of the stiU to a condenser. The latter was a coil of pipe, or a "worm" (hence the expression worm end products), immersed in a tank of miming water. [Pg.202]

Vacuum Distillation. Vacuum distUlation evolved as the need arose to separate the less volatile products, such as lubricating oUs, from petroleum without subjecting these higher boiling materials to cracking conditions. The boiling point of the heaviest cut obtainable at atmospheric pressure (101.3 kPa = 760 mm Hg) is limited by the temperature (ca 350°C) at which the residue starts to decompose or crack. It is at this point that distUlation in a vacuum pipe stUl is initiated. [Pg.202]
