[Haichuan Overseas Engineering] Kazakhstan’s 800,000 tons/year sulfuric acid project has successfully produced qualified products

Thread Content

Recently, the 800,000 tons per year sulfuric acid project in Kazakhstan, undertaken by China National Chemical Corporation and implemented by Tianchen Company, successfully completed the sulfur injection process for the sulfuric acid plant and produced qualified products. The achievement of this milestone not only marks the official entry of this project into a new phase of scaled-up trial operation of sulfuric acid production, but also demonstrates to the world China’s leadership in fields such as the construction of large-scale international projects, comprehensive EPC contracting management, establishment of safety management systems, and inter-disciplinary collaboration. It is reported that the project is located in Zhanatas City, Jiangbul Region, Kazakhstan, where a sulfuric acid plant with an annual production capacity of 800,000 tons will be built. The domestic \"3+1\" two-stage sulfur conversion process will be used, achieving a total conversion rate of up to 99.9%. Upon completion, the project will fill the gap in large-scale, high-standard sulfuric acid supply in Central Asia, and it is of great significance for improving the local chemical industry chain and promoting industrial upgrading. Faced with the complex environment and numerous technical challenges associated with cross-border construction, Tianchen Company’s project team took the lead in developing thorough implementation plans. By leveraging their excellent coordination skills and precise decision-making abilities, they managed to overcome various technical obstacles and implementation difficulties, thus laying a solid foundation for the smooth progress of the sulfonation process. Professional teams in design, procurement, construction, safety, operation, and other areas work closely together, strictly adhering to international standards and project requirements. With their high level of professionalism, pragmatic work style, and rigorous approach to execution, they maintain strict controls over quality and safety throughout the process, ensuring that the sulfonation operations are carried out to high standards and with efficiency. As the core and critical process of the project, the successful completion of this sulfonation operation not only lays a solid foundation for the subsequent stable operation of the sulfuric acid plant at 100% capacity, but also demonstrates Tianchen Company’s outstanding comprehensive capability in project execution and its strength in overcoming technical challenges in complex engineering scenarios. In the future, Tianchen Company will remain committed to the principle of \"providing services that touch customers’ hearts,\" and will use higher-quality technical services to repay the trust and support of its clients ； By continuously focusing on the iterative improvement of production processes and technological innovation, we strive to enable various process units to transform into more intelligent, efficient, and environmentally friendly systems, thereby contributing to the high-quality development of the global chemical industry and the deepening of international capacity cooperation through the efforts of Tianchen.
