This design belongs to the preliminary design. Through to paring the method of producing amsonic acid which domestic and foreign countries mainly use now, we chose the method of palladium and carbon catalysis deoxidization as the optimum one. I take a putation about the raw material and the quantity of heat, and make the equipment shape choice, then reanize the result in this design. Once more, the writter proposes the reasonable measure about processing the three wasters. Finally, I make the choice of factory site and the design of total plane, and carry out the economic accounting about the benefit of this craftwork. The manufactory produces 10,000 tons amsonic acid (99%, w%) when it takes 320 working days every year, then the daily output is tons. Every year it will consume that DNS acid is tons, hydrogen is tons,water is tons,Pd/C catalyzer is tons and promoter OVN is quantity of heat flowing each hour is 106 kJ. The dimension of the responsekettle which is the main equipment is φ . I made a simple economic accounting, the total investment of this project is million Yuan, and the investment ine rate is %, then the time of investment recycling will be years.
