The high-efficiency desulfurization technology developed by the Nanhua University Research Institute has recently successfully passed the scientific and technological achievement appraisal by Sinopec Corporation. This innovative industrial experimental project marks a significant advancement in the field of gas purification.
The technology introduces a high-performance desulfurizer into the traditional tannin solution process, enhancing the removal of hydrogen sulfide from water gas and shift gas. It offers multiple advantages, including a high absorption rate, excellent purification efficiency, easy sulfur recovery, low chemical consumption, and minimal side reactions. The technology has already secured 8 invention patent applications, with 3 of them granted so far. These achievements place it at an international advanced level compared to similar technologies.
In practical applications at the Nanjing Chemical Industry Co., Ltd. chemical plant, the technology was implemented in semi-water gas and shift gas desulfurization systems. The results have been impressive—improved desulfurization performance, stable equipment operation, a notable increase in sulfur recovery, reduced hydrogen loss, and substantial economic and social benefits.
This technology is versatile and can be applied across various industries, such as coal gas, coke oven gas, refinery gas, biogas, and acid tail gas treatment. Its wide range of applications and proven effectiveness make it a highly valuable solution for improving environmental protection and operational efficiency. With its strong potential for large-scale deployment, this innovation is expected to play a key role in the future of clean energy and sustainable industrial processes.
