[Abstract]:In this paper, the development and application of all kinds of flue gas desulfurization processes in China are investigated and analyzed based on the project of raising standard of tail gas in acid-making enterprises from smelting flue gas. The application of regeneration organic amine desulfurization technology in the treatment of acid tail gas from smelting flue gas was explored and studied in this paper. The results show that: firstly, through the analysis of the process route, it is determined that adding the end desulphurization device is the thorough solution to solve the problem of raising the standard of tail gas in acid-making enterprises from smelting flue gas; Through on-the-spot investigation and comprehensive comparison and demonstration, it is confirmed that the regenerated organic amine method is very suitable for upgrading the standard of acid-making tail gas from smelting flue gas. Secondly, combined with the research content and field practice, the optimization design of regeneration organic amine desulfurization process was carried out, and the concrete flow and control parameters of four major processes, namely pretreatment, absorption, desorption and purification, were designed. Four operating conditions are designed to solve the problem of the project, and the optimum design scheme is determined by economic analysis. After the system was completed, the test results showed that the monitoring indexes reached or even better than the original design requirements, and the SO2 in the treated waste gas could realize the ultra-clean emission of 14mg/Nm3. The operating conditions of the system are studied experimentally. The optimum operating conditions are as follows: the steam supply is 5 ~ 6.5t / h, the concentration of sulfate ion is 1.1 ~ 1.3 eq/mol,pH4.8-5.2., and the concentration of ammonium sulfate ion is 1.1 ~ 1.3 mol 路mol ~ (- 1). Finally, according to the trial operation of the system, the operation of the regenerated organic amine desulfurization unit is analyzed from the five aspects of flue gas condition, investment cost, main material consumption index, operation cost and economic benefit according to the original design document. The main index achieves or is better than the designed value and achieves the desired purpose. From the aspects of process technical index, economic benefit, environmental benefit and applicability, the comprehensive comparison with other technical, economic and technical indexes of desulfurization has been carried out, and the obvious economic and environmental benefits of regenerated organic amine desulfurization technology have been confirmed again. It has the best applicability to the project of raising the standard of acid tail gas from smelting flue gas.
