Dear colleagues and friends in the sulfuric acid industry:

Hello everyone!

On behalf of Li Zhenglai Technology (Chongqing) Co., Ltd., today we are filled with great excitement and gratitude to announce a major news to the entire industry:

After two years of dedicated research and development, the digital sulfuric acid OTS 2.0 general version has been successfully completed. It will be made freely available to the Chinese sulfuric acid industry on September 11, 2026, as a general version!

This moment has been awaited for a long time. Since the project was initiated in 2024, our R&D team has firmly believed that we must create a truly useful and practical digital operation training system for China's sulfuric acid industry. Today, this promise has finally been fulfilled.

1. Why do we do this?
Sulfuric acid is known as the "mother of industry". From fertilizer production to the smelting of non-ferrous metals, from petrochemicals to fine chemicals, sulfuric acid is present everywhere. As the world's largest producer and consumer of sulfuric acid, the development level of the sulfuric acid industry directly affects the foundation of the national industrial system.
However, for a long time, our industry has faced a common pain point:
Process optimization is difficult. Traditional process adjustments often rely on the accumulated experience of senior technicians, making it difficult to achieve precise control.
Operation training is difficult. Traditional on-site practical training is not only costly but also poses safety risks. Many key operations dare not be entrusted to new employees to handle.
Emergency drills are difficult. Emergency drills for sudden accidents are limited by the venue and equipment, and many extreme working conditions cannot be simulated.
Personnel training is difficult. The growth cycle of new employees is long, and the experience of technical experts is difficult to pass on.
We understand that digitalization and intelligence are the inevitable paths for the high-quality development of the sulfuric acid industry. But how to take this path? Who will lay the first brick for the industry?
We have decided: This pioneer will be taken on by Li Zhenglai Technology.

2. What makes Digital Sulfuric Acid OTS 2.0 different?
After two years of refinement and iteration, the digital sulfuric acid OTS 2.0 general version has achieved comprehensive upgrades in real simulation, intelligent teaching, and user experience. Now, let us introduce the core advantages of the system to you.

2.1 Real Simulation: Immersive Experience
We use advanced simulation technology to model the entire sulfuric acid production process with high precision. Users can freely conduct training in the simulation environment, understanding the layout and structure of the production facility from multiple dimensions such as on-site equipment, instruments, operations, and safety.
The system supports first-person perspective operation - you can directly click valves, switches, instruments, etc. for interactive operations, and the system will provide real-time feedback on operation results and equipment status changes.
This immersive experience makes operation training no longer limited to dry theoretical explanations, but becomes a vivid and intuitive practical learning. It's like learning by playing games, making learning easy and efficient.
2.2 Intelligent Teaching: Tailored Teaching, Progressive Learning
The system has built-in intelligent teaching management functions, supporting four training modes to meet the needs of different levels of trainees:
Basic Understanding Mode - for new employees, the system provides equipment cognition, process learning, safety knowledge, etc., helping trainees quickly establish an overall understanding of sulfuric acid production.
Operation Training Mode - for on-the-job operators, the system provides normal start-up and shutdown, daily operations, parameter adjustments, etc., helping trainees master operational skills.
Fault Handling Mode - for technical experts, the system presets dozens of common faults and emergencies, and trainees need to analyze the causes and take measures within a limited time to exercise emergency handling capabilities.
Assessment and Evaluation Mode - the system automatically records trainees' operation processes, scoring them from multiple dimensions such as operation accuracy, response speed, safety awareness, etc., providing objective basis for enterprise talent evaluation.

2.3 Free Access: Universal Benefit, Shared Results
This is what we want to emphasize.
We have decided to make the general version of Digital Sulfur OTS 2.0 available for free to the Chinese sulfur industry!
Yes, you heard it right. Free.
As the person in charge of Rizhenglai Technology, I would like to share some heartfelt words with all of you:
"The development of the Digital Sulfur OTS general version would not have been possible without the support of the customers who have been supporting Rizhenglai Technology over the years, as well as the technical support and suggestions from industry colleagues. We hope that by making it freely accessible, every practitioner in the sulfur industry can enjoy the convenience brought by digitalization and jointly promote the digital upgrade of the industry. We firmly believe that only when the overall level of the industry improves can each enterprise truly benefit. This is not only a business decision, but also our industry sentiment and social responsibility."
3. This system can bring what to the industry?
3.1 For production enterprises: Cost reduction, efficiency improvement, safety guarantee
The application value of the Digital Sulfur OTS 2.0 general version can be summarized with four key words:
Reduce training costs. Traditional on-site operation training requires production suspension, which not only causes production losses but also poses safety risks. Using the OTS system for virtual training can complete the skills training of operation personnel without affecting production, significantly reducing training costs.
Improve training effectiveness. The system can simulate various extreme working conditions and emergencies, which are often difficult to achieve in on-site training. Through repeated drills, the emergency handling ability of operation personnel will be significantly improved.
Ensure production safety. The system has a complete safety knowledge base and operating procedures, and during training, trainees can subconsciously form safety awareness and improve theoretical levels, reducing human operation errors and resulting in fewer safety accidents.
Accelerate talent cultivation. New employees can reach the onboarding requirements through system training in a shorter period of time; on-duty personnel can continuously learn and improve their skills levels, and reserve high-quality talents for the enterprise.
3.2 For operators: Skill improvement, career development
For front-line operators, the system provides a safe and free learning platform:
Anywhere and anytime learning. There are no time or location restrictions. As long as there is a computer and internet, one can conduct learning and training, making full use of fragmented time to improve oneself.
Repeated practice to consolidate. For weak points, targeted training can be conducted repeatedly until they are fully mastered. There is no need to worry about operational errors causing equipment damage or safety accidents.
Clear career development path. The assessment and evaluation function of the system allows trainees to clearly understand their skill levels and improvement directions, providing clear guidance for career development.
4. How to obtain and use?
The acquisition and use of the Digital Sulfur OTS 2.0 general version is very convenient:
Step 1: Search for "Digital Sulfur" in the mobile application store and download it.
Step 2: Open the Digital Sulfur APP and register your phone to start using it immediately.
