With an Annual Production Capacity of 500 Tons of Vat Blue RSN Production Process Design
Abstract: Vat Blue RSN is a vat dye, in this article, the production of several typical Vat Blue RSN compare and select technology for 2-amino-anthraquinone as the raw material, after the closed-loop alkali fusion, refining, oxidation method. Two molecules of 2-amino-anthraquinone, potassium hydroxide and sodium hydroxide in the mixed-alkali sodium acetate in the reaction flux. This method is more mature, mild conditions, the products and colors to be more pure, can be dyed to meet the requirements of good. The design is an annual production capacity of 500tons of Vat Blue RSN production workshop, a material balance, heat balance, autoclave body, workshop layout, such as research. Reaction cycle for each 24-hour a day, a grant, through the design, identified as 5 cubic meters of the reactor, including parts of reactor size, stirring gear, accessories and workshop layout design, etc., and draw the production Process flow diagram of the reaction, workshop layout and assembly drawings reactor body.
