Technology Of Amine Resurrection Via Online Purification In Petrochemical Plants

Describes the characteristics of the N-methyl-diethanolamine. Of more than75%of the desulfurization apparatus using MDEA, By analyzing the desulfurization solution composition, Find the cause degradation of the desulfurization solution caused deterioration factors due to the the Heat Stable salts, amino acids, and suspended solids and other impurities in the long-term cumulative. It introduces the characteristics of N-methyl two ethanol amine, and summarized the amine liquid circulation use long-term problems. From causing device amine solvent regeneration foam loss, pollution mechanism and ways to prove Amine resurrection purification technology online promotion inevitability and future prospects for development. Widely used at home and abroad amine Online resurrection purification technology methods and principles, that is the macroporous ion exchange technology and rapid shallow bed ion exchange technology, including the selection and use of equipment. Drawn from the comparative analysis of the experimental data using the the Amine online purification technology enables pollution amine thorough purification. Finally, the application example of Daqing Petrochemical Company and other large enterprises that the cyclic amine purification resurrection simple facilities, Significantly improve the appearance of the purified amine solution, the iron ion content in the amine solution is significantly reduced, Heat Stable Salt Removal obvious, Amine desulfurization capacity has improved significantly, Amine foam height and the defoaming time is improved, And can be a very good economic.
