STUDY AND APPLICATION OF NEW METHOD OF REMOVING COBALT BY ORGANIC REAGENT IN PRODUCTION PRACTICE

In a zinc hydrometallurgy factory a new type of organic agent was studied in addition to production practice methods of purification of cobalt. Through experimental research and production practice it was shown that compared to removal of cobalt by traditional antimony salt method this method has the advantages of low purification control temperature( 75 ~ […]

Simulating Research of the Nitrogen Temperature Control in the Safety Injection System

For the safety injection system(RIS),boric acid solution which covered by pressured nitrogen in the boron injection tank would crystallized while the temperature of the nitrogen was too low. So how to control the temperature of the nitrogen is very important for the safety operation of the RIS. In this paper,the RIS of A nuclear power […]

Preliminary Discussion on Elevator Coating Using Energy-saving and Emission-reduction Techniques

As the elevator coating process is one complicated process, amounts of energy resources such as water, electricity and natural gas are consumed. Its energy consumption has a significant impact on the energy consumption and production costs of the entire enterprise.It is of great significance to study advanced and practical coating energy-saving technology to promote energy […]
