Production method for Triethylene glycol
As a common product of high temperature ethylene oxidation process in the presence of silver oxide catalyst, followed by ethylene oxide hydration for the production of monoethylene glycol diethylene glycol triethylene glycol is commercially available. Other glycol compounds that may be produced in these processes include tetraethylene glycol. Application in natural gas Triethylene glycol is a compound that is used in many cases Used in the oil and gas industry to absorb water in natural gas. It may also be used to absorb moisture from other gases, including other oxygenated gases. For this purpose, it is necessary for the gas to dry to a certain point, because the moisture in the natural gas can cause the pipelines to freeze and cause other problems for the final consumers of natural gas. Triethylene glycol is in contact with natural gas and removes water from it. Triethylene glycol is heated to a high…
Classification of base oils based on physical properties
Classification of base oils based on physical and chemical properties in API Base oils are very different from each other in molecular components and therefore in physical and chemical properties (eg viscosity-temperature properties). For this reason, in 1993, the American Petroleum Association (API) designed an oil classification system and divided all base oils into 5 groups based on the weight percentage of saturated compounds, the weight percentage of sulfur, and the viscosity index, as shown in the table below. It should be noted that the base oil is classified only on the basis of physical and chemical properties and not on the basis of production method. This means that the production method alone does not reflect the level of quality of the base oil. To improve the quality of the base oil, the percentage of unsaturated compounds and sulfur in it should be reduced and the viscosity index of the…
Recycled Base Oil
The definition of second oil recycling and correction has changed over the years. In the past, recycling of working oils could mean many things, in the beginning oils were used as filtration as fuel. In this way, none of the pollutants in your area are removed and it is not suitable for car use. This oil is generally used for fuel. The correction process of the second year causes all impurities, location and insolubility and return of oil as base oil to be fresh. This second refining base oil is equal to or better than some virgin base oils (produced from crude oil) and is suitable for use in cars. The second oil refining process is shorter than crude oil refining and uses less energy After draining, the oil is passed through a filter in two stages and the filtration operation is performed to separate the coarse particles and then…
