Description

technical field [0001] The invention relates to the technical field of propylene, in particular to a quantitative feeding device for propylene purification and a feeding method thereof. Background technique [0002] Propylene is an organic compound with a molecular formula of C3H6. It is a colorless, odorless, slightly sweet gas. It is flammable and will produce bright flames when burned. The explosion limit in air is 2% to 11%; Insoluble in water, soluble in organic solvents, it is a low-toxic substance; propylene is one of the basic raw materials of the three major synthetic materials, and its consumption is the largest in the production of polypropylene; in addition; propylene can be used to prepare acrylonitrile, propylene oxide, Isopropanol, phenol, acetone, butanol, octanol, acrylic acid and its esters, propylene glycol, epichlorohydrin, and synthetic glycerin, etc.; the chemical properties of propylene are determined by its double bond and the hydrogen atom on the all...

AI Technical Summary

Problems solved by technology

[0003] A quantitative feeding device and its feeding method for propylene purification in the prior art have the following problems: since propylene is a colorless, odorless, slightly sweet gas, it is necessary to purify the gas Due to the inconvenient adjustment of the size of the feed material during processing, the gas treatment effect is not efficient enough, and the impurities contained in the gas cannot be pretreated
