The "Project of Salt Recovery and Refining Technology from Coking Desulfurization Waste Liquid" is a key project in Shandong Province and has been selected into the Innovation Capacity Enhancement Project for Technology-Based Small and Medium-Sized Enterprises in Shandong Province. AMS, a subsidiary of Shuifa Hi-Tech Group, promotes and implements the project through the whole chain of "pain point tackling - innovation support - value release", realizing a qualitative transformation of the technology from the "laboratory" to the "industrial end".

Anchor specific pain points in the industry

The technical project achieves precise breakthroughs.

The coking industry generates millions of tons of desulfurization waste liquid annually, which contains highly toxic by-salts and has complex components. Traditional treatment processes often have many problems to be solved urgently, such as the purity of by-salts being less than 85% (making them unable to be reused in industry and leading to resource waste), high energy consumption (not conforming to the requirements of the "dual carbon" strategy and low-carbon transformation), and the "treatment-then-discharge" model (causing water resource waste).

In response to these pain points, guided by market demand, AMS established a special R&D team and jointly developed the "coking desulfurization waste liquid salt refining technology" with Shandong Jianzhu University. This technology has achieved multiple breakthroughs: it can make the purity of ammonium thiocyanate meet the standard of industrial premium products (solving the purity problem); through the innovative "salt separation and extraction" process, its energy consumption is reduced by more than 40% compared with traditional processes; the wastewater reuse rate exceeds 80% and the by-salt recovery rate reaches 95%, realizing a whole-chain treatment system of "water conservation - pollution reduction - resource utilization". In the first half of 2025, this technology was recognized by the Shandong Association of Science and Technology Consulting as reaching the domestic leading level, marking a key transformation of the technology from "laboratory achievement" to "market-oriented application".

Building Multi-Dimensional Innovation Support: Consolidating the Foundation for the Implementation of the Technology Project

A stable support system has been built for the "Project of Salt Recovery and Refining Technology from Coking Desulfurization Waste Liquid" from the three dimensions of innovation qualification, university-enterprise collaboration, and R&D support to ensure the implementation of technological achievements.

The company has deepened cooperation with Shandong Jianzhu University. Relying on the university's scientific research advantages and the company's engineering experience, it completed the leap from "laboratory test" to "pilot test" of the technology in 6 months and quickly passed the achievement evaluation. At the same time, it has promoted the application of relevant technologies for industrial water-saving processes and central government-guided local science and technology development fund projects, forming an innovation matrix. In the first half of the year, more than 3 million yuan was invested in technology optimization and iterative upgrading, laying a foundation for subsequent project applications and subsidy acquisition, and forming a sound innovation cycle.

In the first half of the year, the company was recognized as a Jinan Municipal Enterprise Technology Center, passed the re-examination for Shandong Province's "Specialized, Refined, Peculiar and Innovative" small and medium-sized enterprises, obtained 3 utility model patents and 1 invention patent, completed the registration of technological achievements and the application for "China's Good Technology". These efforts have built a complete intellectual property protection barrier for the core technology, effectively safeguarding the exclusive advantage of the technology in market promotion.

Releasing Dual Quantitative Values: The Technology Project Empowers High-Quality Development

Relying on the market competitiveness of the "salt recovery and refining technology from coking desulfurization waste liquid", the company has made every effort to promote the accurate connection between the technology and project needs. In the first half of the year, it signed a number of key water treatment projects with a contract value of 155 million yuan. The "Project of Salt Recovery and Refining Technology from Coking Desulfurization Waste Liquid" has achieved a revenue growth of more than 30%, becoming the core driving force for the company's operation and development.

Meanwhile, social benefits have been released. A single project helps cooperative enterprises achieve a water and salt recovery rate of 95%, reduce water consumption by more than 500,000 tons per year and salt waste by more than 2,000 tons, and enables cooperative enterprises to reduce treatment costs by more than 40%. The "Project of Salt Recovery and Refining Technology from Coking Desulfurization Waste Liquid" has been included in the "Catalogue of Jinan's Advantageous Industrial Products" and become the first choice for the upgrading of 3 local coking enterprises, contributing to the transformation and upgrading of the regional industry.
