- 摘要:
以络合铁法脱硫技术为代表的天然气液相氧化还原脱硫技术具有环境友好、安全经济、脱硫效率高等优势,广泛应用于潜硫量为0.2~10 t/d的气体脱H2S净化领域。但络合铁法脱硫技术存在装置易堵塞、再生设备尺寸大、硫膏品质低等应用挑战,制约了进一步发展。总结分析了近年来络合铁法装置防堵技术、再生设备小型化技术、硫膏高值资源化等方面的研究成果。指出需继续对络合铁法脱硫溶液体系进行创新升级、加强设备橇装化设计、优化硫膏熔硫精制技术运行成本,以突破新技术工业应用的障碍,提高络合铁法脱硫装置的长周期运行稳定性、经济性和推广性。
Benefitting from advantages such as environmental friendliness, safety, cost-effectiveness, and high desulfurization efficiency, the liquid-phase redox desulfurization technologies, represented by the chelated-iron desulfurization technology, are widely applied in the purification of H2S-containing gases with a latent sulfur content of 0.2~10 t/d. However, the inherent technical challenges of this technology—such as equipment blockage, large equipment size and poor sulfur paste quality—have hindered its development. This paper summarizes recent research achievements in areas such as anti-blocking, regeneration equipment miniaturization, and resource utilization of by-products in chelated-iron process. However, further innovation in the desulfurization solution system, optimization of operating costs for sulfur paste refining, and enhanced skid-mounted equipment design are necessary to overcome barriers to industrial application and to improve the long-term stability, cost-effectiveness, and promotion of chelated-iron desulfurization units.
