Technical kerosene KT-1 is a high-demand oil product. It is obtained from oil by rectification and is a combustible flammable liquid. After distillation under pressure and at high temperature, the obtained hydrocarbon mixture is subject to dearomatization or hydro treatment, depending on its further application.
Technical kerosene is a popular industrial product which is applied in various fields:
- as a base for ethylene and propylene production;
- as a fuel for glass and porcelain treatment equipment;
- as a cleaning and degreasing agent for industrial equipment;
- after hydrogenation it can be used for the production of PVC;
- adding salts of chlorine and magnesium in it prevents static electricity;
- in everyday life it is used as a solvent, it also can thin up the paint;
- in some cases, it is used as a lamp kerosene.
As well as the KT-1 brand, KT-2 kerosene is used for technical purposes. The combustible liquid of this brand is denser than KT-1, it has different acidity, sulfur content (the amount of sulfur is 6 times more), high resin content, lower flash point (28 ° C in KT-2 vs. 38 ° C in KT-1).
Generally, KT-1 kerosene is better and more environmentally friendly than KT-2, but each of the brands occupies its own niche in the industry and is popular. Together, these two types of kerosene are the most common.
Kerosene is a mixture of hydrocarbons with different structures: aliphatic, naphthenic, bicyclic and unsaturated. Their percentage ratio is unstable and can vary within acceptable limits. Therefore, the molar mass of kerosene is unstable too and depends on hydrocarbon concentration which is different for each oil processing method.
As well as hydrocarbons of different groups, technical kerosene contains impurities from nitrogenous, oxygen and sulfur components.
Technical parameters of each brand of kerosene are regulated by GOST.
- Density at 20°С – from 780 to 850 kg/cu. m.
- Viscosity at 20°С – from 1.2 to 4.5 kg/cu. m.
- Does not contain mechanical impurities and water.
- Does not contain water and alkalis.
- Flash point – from 28 to 70 ° C depending on brand and degree of purification.
- Combustion heat – not less than 43 MJ / kg.
Kerosene is produced by oil refineries and plants.
