Southwest Institute wins bid for two pressure swing adsorption hydrogen recovery units in the second phase of Yulin Chemical project

Thread Content

Recently, Southwest Institute won a contract from Shaanxi Coal Group Yulin Chemical Co., Ltd. for the first-phase of the demonstration project on the clean and efficient conversion of coal at a capacity of 15 million tons per year; this project involves the construction of units for the synthesis of methanol, as well as two pressure swing adsorption hydrogen recovery units. Each of these units is capable of producing 6,500 Nm³/h of hydrogen. Relying on its own proprietary high-pressure pressure swing adsorption technology, the Southwest Branch will provide a complete set of detailed designs as well as key equipment such as specialized adsorbents and programmable valves. The operating pressure of this hydrogen recovery unit is 6.0 MPa; it produces high-quality hydrogen with a purity of ≥99.9% and a CO content of ≤1 ppmv, meeting the hydrogen demand of downstream processes while maximizing the recovery of hydrogen resources and reducing emissions. The project team at the Southwest Branch continuously optimizes the technical solutions to reduce land use and lower investment and operating costs. Advanced timing control methods are used to precisely regulate pressure, while high-quality adsorbents and special valves are employed to meet the demands of high-pressure and harsh operating conditions. It is reported that the Demonstration Project for the Clean and Efficient Transformation of Coal into High-Value Products by Yulin Chemical Company serves as the key platform for Shaanxi Coal Group to develop a world-class cluster of high-end chemical material industries. It holds strategic significance for ensuring energy security, promoting the clean and efficient transformation of coal, and advancing the development of the new chemical materials industry. This successful bid marks another collaboration between Southwest Research Institute and Shaanxi Coal Group, following their partnership in 2019 on a project involving an 1.8 million tons per year ethylene glycol production facility along with a large-scale pressure swing adsorption hydrogen production system. It further strengthens Southwest Research Institute’s leadership in the field of large-scale high-pressure pressure swing adsorption technologies, and it also adds to its track record of providing comprehensive support for major energy projects and helping clients achieve a green and low-carbon transition.
