Cracks that would normally have been invisible are detectable due to the magnetic particles clustering at the crack openings. The scale at the bottom is numbered in centimetres. Magnetic particle inspection ( MPI ) is a nondestructive testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities ...
The Swedish Transport Administration electric road program (Swedish: Trafikverkets Program för Elvägar) or Swedish Transport Administration Electrification Program (Swedish: Trafikverkets Program för Elektrifiering) [1] is a program involving the assessment, planning, and implementation of an electric road national infrastructure for Sweden by Trafikverket, the Swedish Transport Administration.
Steam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial method for producing the lighter alkenes (or commonly olefins ), including ethene (or ethylene ) and propene (or propylene ).
The Lurgi–Ruhrgas process is a hot recycled solids technology, which processes fine particles of coal or oil shale sized 0.25 to 0.5 inches (6.4 to 12.7 mm). As a heat carrier, it uses spent char or spent oil shale (oil shale ash), mixed with sand or other more durable materials.
Naphtha, natural gas, refinery off-gas and gas from cokers and thermal crackers are good sources. Thus natural gas is one of the most wanted feed stocks for petrochemicals production. The thermal cracking of natural gas proceeds at very high temperature resulting in olefins (Mostly ethylene/propylene). The temperature in a gas cracker exceeds ...

Shukhov designed and built the first thermal cracking device for the petrochemical industry.His patent (Shukhov cracking process – patent of Russian empire No. 12926 from November 27, 1891) on cracking was used to invalidate Standard Oil's patents (Burton process – Patent of United States No. 1,049,667 on January 7, 1913) on oil refineries.
