On July 2, 2026, the 2026 Sulfuric Acid Industry Annual Conference was grandly launched in Wuhan. Over 200 units from upstream and downstream of the industry chain and 500 industry representatives gathered in the city, focusing on the problems of raw material supply and demand, discussing core technologies of low-carbon intelligent manufacturing, and jointly planning the green, intelligent and high-quality development blueprint for the sulfuric acid industry during the "15th Five-Year Plan" period. Li Zhenglai Technology (Chongqing) Co., Ltd. showcased its complete digital sulfuric acid solution, self-developed specialized equipment and high-precision high-end specialized instruments at this exchange meeting. The domestic innovation solution directly hit the industry's pain points, attracting a large number of colleagues from acid factories to stop by for consultation, and the event was extremely popular.

At the current Wuhan exchange meeting, the venue was crowded with representatives from various sulfuric acid production enterprises, engineering technicians, and environmental protection operation managers. They all came to our company's exchange booth to deeply understand the digital sulfuric acid one-click start-up system, the OTS simulation training platform, the automatic condensation acid discharge device, and the full range of high-temperature acid concentration instruments. Many factory managers and process engineers on-site experienced the digital sulfuric acid APP and the OTS simulation operation interface. Regarding the first-line pain points such as sulfide gun blockage, inaccurate high-temperature acid concentration measurement, unorganized acid mist emission, and difficulties in training new operators, they had in-depth exchanges with our technical team about equipment operation conditions, project implementation cases, renovation costs, and operational advantages. Many enterprises expressed their intention to cooperate on the spot and planned to conduct on-site inspections of the factory and negotiate the digital upgrading and transformation projects of the equipment after the meeting.

Respond to customer inquiries and optimize product upgrades

While fully recognizing the practical value of the domestically produced and digitized equipment of Li Zheng, the on-site industry customers, based on their years of practical production experience in the factory, proposed many highly valuable and constructive suggestions from multiple aspects such as implementation, scenario adaptation, and operational convenience for product iteration and solution optimization.

For the position of a technical operator in the production of sulfuric acid, how should the enterprise establish a full-chain talent cultivation mechanism that encompasses "precise recruitment, long-term retention, and career advancement"?

The traditional "master-apprentice system" often leads to technological gaps and talent loss. The digital solution proposed by Li Zenglai can fully establish a long-term talent mechanism: 

① Precise recruitment to fill the gap of specialized talents 

Relying on the expertise of Li Zhenglai in process, instruments and digitalization, we precisely select skilled technicians who possess both the capabilities of the sulfuric acid process and digital operation and maintenance. At the same time, we provide systematic process training for the internal team of the enterprise to quickly fill in the technical gaps of the team. 

② Simplify operations, reduce risks, and stabilize frontline personnel 

Digital sulfuric acid system + mobile APP solidifies production process experience. Employees can access production parameters and process plans at any time. Our self-developed high-precision high-temperature acid concentration instrument replaces manual titration, significantly reducing operational difficulty and safety risks, thereby enhancing the attractiveness of job retention. 

③ Simulation training opens up the path to promotion 

The OTS simulation system is combined with an online question bank, allowing employees to virtually practice driving, adjusting load, and handling faults. Enterprises can digitize their production experience and enable employees to transition to high-value positions such as data analysis and process optimization, thereby expanding their career paths.

2. In the face of the significant increase in sulfur prices, how can Digital Sulfur Technology provide core solutions to help enterprises reduce costs, increase efficiency, and hedge risks?

Relying on the digital sulfate system and with "material balance" as the core design concept, control costs and increase efficiency from three aspects: raw materials, manpower, and operation and maintenance. 

Intelligent material management to reduce sulfur loss 

Real-time collection of production data for modeling and calculation, intelligent correction of process parameters, reduction of abnormal sulfur consumption, and hedging against raw material price increases from the source. 

② Fully automatic intelligent control, saving labor costs 

The linkage of DCS/APC systems enables one-click start-up and automatic load adjustment, allowing the equipment to operate in the long-term stable and optimal condition. This reduces labor costs and enhances production efficiency. 

③ Automatically predict faults and reduce equipment operation and maintenance costs 

Carry out online diagnosis of process abnormalities, avoid corrosion and over-limit issues, reduce unplanned shutdowns, extend equipment maintenance cycles, and lower maintenance and replacement costs.

3. What are the core development trends in the current sulfuric acid industry? How should enterprises accurately seize the opportune period for industrial upgrading and the explosive demand for new energy?

Industry core trend: Say goodbye to extensive expansion of production, and fully embrace green and low-carbon, intelligent control, and high-end refinement. Three development windows of opportunity can leverage Rizheng's technology for implementation: 

Intelligent Low-Carbon Transformation Window 

Environmental protection regulations have tightened. Relying on Li Zheng and Haili Si to jointly establish an exclusive digital system for the intelligent joint laboratory, we will build a standardized intelligent production line and complete the green technological transformation. 

② A New Pathway for Phosphogypsum-Based Acid Production Cycle 

Phosphogypsum-based acid production reduces reliance on sulfur raw materials. Li Zhenglai's load-adaptive control technology is integrated to support the resource utilization of solid waste and help enterprises achieve cost reduction through circularity. 

③ High-end market window for electronic-grade sulfuric acid 

New energy and semiconductors have driven the demand for high-purity sulfuric acid. Through self-research and domestic production, we have developed high-precision acid concentration detection and sealed sampling equipment, breaking the monopoly of foreign equipment and ensuring the stability of high-purity product quality, thus entering the high-value-added market segment.

Join hands with industry colleagues and embark together on the "15th Century" journey of high-quality and low-carbon development.

This year's Wuhan Industry Annual Conference brought together the entire industry chain, focusing on three major development directions: low-carbon, intelligent, and safety. Rizhenglai, as a pioneer in the digitalization of sulfuric acid and the domestication of specialized equipment, with a complete product matrix including simulation training systems, fully automatic production control systems, sealed environmental protection equipment, and high-temperature specialized instruments, provides the industry with low-cost, high-security, and intelligent upgrade solutions. Many representatives from acid factories at the scene highly recognized the value of our digital and domesticated products, and look forward to further deepening cooperation to jointly promote the intelligent and green transformation of the factory. 

In the future, Li Zhenglai will continue to deeply focus on the sulfuric acid sub-segment market, using technological innovation to address the pain points throughout the measurement, production, environmental protection and training processes of the industry. It will collaborate with upstream and downstream enterprises to promote the digitalization and low-carbon transformation of the domestic sulfuric acid industry, and jointly write a new chapter of high-quality development for the industry in the "15th Five-Year Plan" period.
