Oil refinery - Wikipedia

Oil refinery - Wikipedia

An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oil …

petroleum refining | Definition, History, Processes ...

petroleum refining, conversion of crude oil into useful products. The refining of crude petroleum owes its origin to the successful drilling of the first oil wells in Ontario, Canada, in 1858 and in Titusville, Pennsylvania, U.S., in 1859. Prior to that time, petroleum was available only in very small quantities from natural seepage of subsurface oil in various areas throughout the world.

Sample-size requirements are in the range of 10-100 M of N. Nitrate samples can also be analyzed for d 18 O in a few laboratories. An alternate method is to concentrate the NO 3 or NH 4 on anion or cation exchange resins (Garten, 1992; Silva et al., submitted; Chang et al., in review). Collection of nitrate on anion exchange resins eliminates ...

Sep 23, 2014 Students could make esters by reacting alcohols with carboxylic acids, purifying the product using a separating funnel and by distillation. AT b, d, g, h and k Students could identify an ester by measuring its boiling point, followed by hydrolysis to form the carboxylic acid, which is purified by recrystallisation, and determine its melting point.

where t R refers to the retention time of the peak and W b refers to the peak width at baseline in Equation 8-2 and W h its width at half-height in Equation 8-3. Figure 8-3 illustrates the values used with these equations. The higher the plate number N, the greater the efficiency of the column. One can understand quickly that the narrower the peak (low W), the higher N, and …
