Refinery - Wikipedia

The image below is a schematic flow diagram of a typical oil refinery depicting various unit processes and the flow of intermediate products between the inlet crude oil feedstock and the final products. The diagram depicts only one of the hundreds of different configurations. It does not include any of the usual facilities providing utilities such as steam, cooling water, and electric power as ...Read more

Poly(chloroethene) (Polyvinyl chloride)

The catalyst generally used is a mixture of copper(ll) and potassium chlorides, deposited on alumina. As the reaction is highly exothermic, the reactor vessel is cooled to give the optimum reaction temperature and to reduce unwanted by-product formation of, for example, chloroethane and 1,1,1,2-tetrachloroethane. 95% conversion of ethene to 1,2-dichloroethane is obtained.Read more

Chemical reactors - Essential Chemical Industry

A common heat exchanger is the shell and tube type (Figures 12 and 13) where one part of the process flows through a tube and the other part around the shell. A good example where heat exchange is important is in the manufacture of sulfur trioxide from sulfur dioxide in the Contact Process where the excess heat is used to warm incoming gases.Read more

This process of growth and isolation is time-consuming, and results typically require 7-14 days from the time of submission. Cultured samples can also be analyzed to identify specific serogroups. Matching the same serogroup and subtype of organism in the patient as found in a water source is considered strong evidence of an associated link.Read more

Aug 09, 2020· Schematic diagram of a solid-phase microextraction device. The absorbent is shown in red. Two additional methods for isolating volatile analytes are a purge-and-trap and headspace sampling. In a purge-and-trap, we bubble an inert gas, such as He or N 2, through the sample, releasing—or purging—the volatile compounds. These compounds are ...Read more

Hydrocracking - an overview | ScienceDirect Topics

James G. Speight, in The Refinery of the Future, 2011 9.1 Introduction. Hydrocracking is a refining technology that falls under the general umbrella of hydroprocessing.The other technology, hydrotreating (Chapter 8), is also called hydrodesulfurization (HDS); and is a catalytic refining process widely used to remove sulfur as well as other unwanted compounds from petroleum products such as ...Read more

Oil refinery - Wikipedia

An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of ...Read more
