Capability Description
View Original

"A proprietary technology certified by the industry association, addressing the recovery challenge of heavy soda filter mother liquor in soda ash production. This technology employs a vacuum distillation process route to achieve efficient separation and recovery of ammonia and carbon dioxide from the mother liquor at relatively lower temperatures. Compared with traditional atmospheric distillation, this technology significantly reduces steam consumption, improves distillation efficiency, while simultaneously mitigating equipment corrosion and scaling issues.

This technology is applicable to energy-saving transformation of the distillation process in ammonia-soda process soda ash enterprises, and can also serve as the preferred solution for new soda ash plant distillation systems. Deliverables include the proprietary technology process package, key equipment selection guidance, and on-site调试 support."

An industrialized application technology that has won the Second Prize of the Provincial Science and Technology Progress Award. This technology deeply couples underground salt mine extraction with soda ash production, achieving integrated above-ground and underground cyclic production of salt, alkali, and calcium. Waste liquid from soda ash manufacturing is injected into underground solution cavities for salt mining, while the extracted brine serves as raw material for soda ash production, forming a closed-loop cycle. This technical route fundamentally resolves the environmental bottleneck of waste liquid discharge in the ammonia-soda process while significantly improving the utilization rate of rock salt resources. It has been successfully implemented in large-scale domestic projects for the comprehensive utilization of rock salt resources. The related engineering design has received First Prizes for Excellent Engineering Design at both provincial and municipal levels. This technology is suitable for soda ash production enterprises possessing rock salt mineral resources.
