The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron.

Göran Fredrik Göransson (20 January 1819 – 12 May 1900) was a Swedish merchant, ironmaster and industrialist.He was the founder of the company Sandvikens Jernverks AB (now called Sandvik AB) and was the first person to implement the Bessemer process successfully on an industrial scale and pioneered ingot steel in the Swedish iron and steel industry.
Bessemer licensed the patent for his process to five ironmasters, but from the outset, the companies had great difficulty producing good-quality steel. [19] Mr Göran Fredrik Göransson , a Swedish ironmaster, using the purer charcoal pig iron of that country, was the first to make good steel by the process, but only after many attempts.
A company's place on the matrix depends on two dimensions – the process structure/process lifecycle and the product structure/product lifecycles. [1] The process structure/process lifecycle is composed of the process choice (job shop, batch, assembly line, and continuous flow) and the process structure (jumbled flow, disconnected line flow, connected line flow and continuous flow). [1]
From the earlier research and ways to evaluate process model quality it has been seen that the process model's size, structure, expertise of the modeler and modularity affect its overall comprehensibility. [24] [27] Based on these a set of guidelines was presented [28] 7 Process Modeling Guidelines (7PMG). This guideline uses the verb-object ...

Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer).However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical ...
