On April 8, Liu Jianli, director of the Petroleum Processing Research Institute at Qilu Petrochemical Research Institute, contacted by phone the relevant personnel in charge of Jinling Petrochemical’s 150,000 tons per year sulfur recovery unit to provide technical services and guidance. After the 150,000 tons per year sulfur recovery unit at Jinling Petrochemical adopted the efficient Claus sulfur recovery technology independently developed by Qilu Petrochemical Research Institute, the unit operated stably at full capacity, contributing to cleaner production. At present, the core catalyst for this technology has been successfully applied in sulfur recovery units at various domestic enterprises. This technology is an important green technological innovation achievement of Qilu Petrochemical; it represents another major breakthrough in sulfur recovery technologies and is unique both domestically and internationally. After the application of this technology, the sulfur recovery rate in the sulfur recovery unit reaches 99.13%, the sulfur dioxide emission concentration in the flue gas after desulfurization is less than 10 milligrams per cubic meter, and the utilization rate of sulfur as a resource reaches 99.999%. “The project “Development and Application of High-Efficiency Claus Sulfur Recovery Technology” won the Second Prize of the 2024 Sinopec Science and Technology Progress Award. Qilu Petrochemical is the only company within Sinopec that is engaged in the research and development of complete environmental protection technologies for sulfur handling, as well as various catalysts. It boasts nearly 50 years of experience in developing sulfur production technologies, and its level of research and development is among the best in the world. In recent years, the requirements regarding sulfur dioxide emissions from sulfur-related facilities have become increasingly stringent. Shandong Province has even established the strictest emission standards in the world; currently, there are no mature and reliable technologies available either domestically or internationally to meet these standards, which makes it urgent to carry out systematic research and development on sulfur recovery technologies. Qilu Petrochemical bears the imperative responsibility to take on this task. While focusing on the development of comprehensive sulfur pollution control technologies and various catalysts, it continuously improves its mechanisms for scientific and technological innovation, makes full use of the advantages of its own research institutions, fosters an environment conducive to innovation, increases investment in research and development, and strives to make progress in addressing key core technologies. In the early stages of developing high-efficiency Claus sulfur recovery technology, there was no existing experience to draw upon. To develop high-performance core catalysts, Liu Jianli led his team members in an in-depth exploration of the reaction mechanisms and a thorough analysis of the catalytic process, carefully examining, improving, and optimizing each performance parameter. “There are many ways to combine and match active components; one must be patient in making calculations and keep making adjustments. There’s no room for haste, nor can any carelessness be tolerated.” ”Liu Jianli explained that in the sulfur micro-reaction evaluation laboratory, they carefully simulate various conditions under actual industrial settings in order to continuously improve the performance of the catalysts. During the experiment, team members worked in shifts, continuously recording and adjusting operational parameters 24/7, performing calculations over and over again and starting from scratch each time, in an effort to find the optimal solution through countless attempts. Hard work pays off, and the team members ultimately overcame this tough challenge, completing the research and development task of \"Developing and Applying Efficient Claus Sulfur Recovery Technology.\" The project was approved by Sinopec’s headquarters in August 2024. After reviewing the project work report, technical report, and reports on application and economic benefits, relevant experts unanimously agreed that this achievement can drive innovation in sulfur recovery technologies and promote the development of the industry related to technologies for treating sulfur-containing waste gases. It can result in cost savings of over 30% for new installations, as well as a reduction in operating costs by more than 40%. The economic and social benefits are significant, making it suitable for various sulfur recovery systems used in the petrochemical industry, coal chemical industry, and natural gas purification industry. After the successful development of this technology, the project team intensified its exchanges with various enterprises to accelerate the transformation and widespread application of the technical achievements. To ensure the smooth industrial application of the technology, the project team followed the principle of \"one strategy per enterprise\" by visiting the relevant companies in advance to understand the actual operating conditions of their sulfur treatment facilities. They prepared detailed process packages and renovation plans, and monitored every stage of the process, including catalyst installation, facility commissioning, initial operation maintenance, and calibration. Through various methods such as on-site guidance, video conferences, and telephone communications, they provided technical support and guidance, earning the recognition and praise of their clients. Liu Jianli explained that the set of technologies for ultra-low sulfur emission and resource utilization of sulfur-containing waste gases in refining, which were developed by Qilu Petrochemical and possess independent intellectual property rights, won the Second Prize in the Science and Technology Progress Award. The sulfur recovery rate achieved through these technologies is at an internationally leading level; they have been applied in 81 units across 32 enterprises, while the catalysts used in these technologies have been employed in more than 300 units both domestically and abroad.
