With extensive engineering design experience in the soda ash and combined soda ash sectors, over 300 related projects have been completed in the past 15 years, covering full-stage services including feasibility studies, preliminary design, construction drawing design, and dedicated safety facility design. Design expertise spans the two mainstream process routes: the ammonia-soda process and the combined soda ash process, with a track record of individual project scales ranging from tens of thousands of tons per year to the million-ton-per-year level. In recent years, engineering design has been delivered for multiple large-scale new and expansion soda ash projects domestically, as well as overseas design services for the Yiyu 300,000-ton-per-year soda ash project. Several representative projects have received national and provincial/municipal-level awards for excellent engineering design. Engineering design services cover all disciplines, including overall plant layout, process, equipment, piping, electrical, instrumentation, water supply and drainage, HVAC, building structure, and cost estimation.
