Oil refining also need a thermometer? What kind of precise?

Gasoline, diesel, or some plastic products and so on, are familiar, but seen these oil fewer original face, we meet and come into contact with oil are mostly by oil processing products. For these products is how to you the less you know. The popularity of today will give you a brief about some requirements on the temperature in the process of petroleum refining. In simple terms, the oil refining mainly USES the atmospheric and vacuum distillation range of simple physical method will be cut for the boiling point of crude oil different size and density of various petroleum fractions. Various fractions separation sequence mainly depends on the molecular size and the boiling point. In the process of atmospheric distillation, small gas molecules, low boiling point ( 50～200℃） , first of all, distillate, followed by kerosene ( 60～5℃） And diesel, 200～0℃） , residual heavy oil. Heavy oil by vacuum distillation and can obtain a certain amount of lubricant base oil or semi-finished products ( Wax oil) And the last remaining residue ( Heavy oil) 。 Of course this is just a simple introduction of oil refining process, to get a more complete industrial products need further processing. Since the temperature in the process of petroleum refining master is very important, so is more strict with the thermometer. Instrument of the bimetallic thermometer can realize the temperature control in petroleum and chemical. Models: T300E detachable cover types: hot shell bimetallic thermometer structure: axial type, cover circle: detachable material: stainless steel SS304 tooth head: 1/2 & quot; BSP, other optional surface diameter: 63 mm, 100 mm optional heat pipe diameter: 6. 35 mm heat pipe length: 100 mm ( 50 - Optional) around 400 mm. Temperature range: - 10 - 120 c F( Can be customized) Accuracy: & plusmn; 2 - 1. 5 - Table: 2% glass protection grade: IP55 ( Dust, water) Product features: the product cover ring can be removed, easy to clean up and adjust, the display temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Don't look at the tiny thermometer, it is an essential tool for industrial development.
