The significance of digital sulfuric acid

The digital economy has become the core driving force for a new round of global scientific and technological revolution and industrial transformation. China is committed to promoting the high-quality development of the digital economy, promoting the deep integration of digital technology and the real economy, and promoting digital industrialization and industrial digitization, so as to comprehensively enhance the driving force of economic and social development. Under the dual background of digital economy era and sustainable development strategy, the sulfuric acid industry urgently needs transformation and upgrading. As “ The mother of industry ” The output of sulfuric acid was once a key indicator to measure the level of national industrial development. However, the shortage of human resources, low energy efficiency and safety and environmental protection problems faced in the production process of sulfuric acid have seriously restricted the healthy development of the industry. The application of digital sulfuric acid technology provides innovative solutions to meet these challenges, which can not only alleviate the shortage of human resources, but also improve the production efficiency of sulfuric acid, and effectively reduce the impact on the environment, helping to achieve the goal of green sustainable development.

(1) The main functions of digital sulfuric acid

Digital sulfuric acid has a variety of functions designed to meet the production and management needs of the sulfuric acid industry. These features cover but are not limited to

1, production automatic operation: through the use of digital sulfuric acid DCS control system (WSA-100), the sulfuric acid plant production process automatic operation. The system ensures that the device can operate automatically without manual intervention under various load states. In addition, it can precisely control the various process parameters to keep them within the allowable target value range and ensure the stability of the operating data.

2, safety automatic control: to ensure the safe operation of the device in any state is the basic requirement for the automatic operation of the device. For the safety automatic control of the sulfuric acid device, digital sulfuric acid has a complete control strategy to meet the safety inspection of the sulfuric acid device before start-up, safety control during start-up, safety protection during operation, and safety control of parking and unplanned parking. This is intended to prevent safety incidents caused by personnel negligence.

3, operation skills training: in view of the sulfuric acid plant production has been automated operation, the company's operators and management personnel to the operating state of the device is weakening year by year. Without timely skills training for employees, they may be overwhelmed in the face of emergency situations in the future, which will pose serious security risks and survival challenges for enterprises. The digital sulfuric acid APP integrates four functions: technical data, training questions, factory simulation, and equipment details, aiming to improve the skill level of sulfuric acid plant operators. Through the promotion and application of digital sulfuric acid APP, the skill level of relevant personnel in the enterprise is expected to reach the industry-leading level, ensuring that fault analysis and treatment can be carried out quickly in any abnormal situation, and effectively alleviating the shortage of professional skills in the enterprise.

4, to achieve efficient management of the device: in the current fierce competitive environment of all walks of life, in order to maintain the market competitiveness of enterprises, the sulfuric acid industry must ensure that its operation of high energy efficiency, long periodicity and low failure rate. In order to achieve this goal, the key lies in the management function deep into the production line, and realize the transparency of management. In this way, the personnel involved in the production of sulfuric acid can quickly grasp the real-time status of the device. By improving the transparency of device operation information, the barriers between technical specialties can be eliminated, the efficiency of fault handling can be improved, and the technical standards related to enterprises can be established. The Digital Sulfuric Acid DCS System (WSA-100) develops the integrated information and material balance function of the sulfuric acid plant, digitizing the operation data of the plant, and generating operational information that is easy for all personnel to understand. The material balance function allows the unit to be compared with design standards in real time during operation, to detect potential risks in time, and to optimize process parameters to ensure that the unit is always in optimal operation.

(2) Application effect of digital sulfuric acid

The application of digital sulfuric acid will create significant value in the sulfuric acid industry. Specifically, it is mainly reflected in the following aspects:

1, improve production efficiency: Through the implementation of automated operation and digital management of the production process, digital sulfuric acid can get rid of the inconsistent production mode of dependence on personnel, thus significantly improving the production efficiency of sulfuric acid and the consistency of process indicators.

2, energy saving and emission reduction: through unified automatic control and real-time optimization calculation of energy efficiency, automatically adjust to the best oxygen/sulfur ratio control value; Optimize the operating parameters and operating conditions of the sulfuric acid plant to ensure that the plant is always in the best state of energy recovery, while reducing the SO2 content at the outlet of the secondary suction tower and reducing the energy consumption required for tail gas treatment.

3, ensure the stable operation of the device: digital sulfuric acid can monitor and analyze the operating status of the device in real time, identify and solve potential problems in time to ensure the stable operation of the device.

(3) Development trends and challenges

In the future, the application of digital sulfuric acid in the sulfuric acid industry will show the following trends:

1, deep integration: The deep integration of industry and digital technology is gradually becoming the mainstream trend. By building a highly intelligent digital sulfuric acid control system, we are able to integrate sulfuric acid production, management, training and technology research and development into smart terminals such as smartphones. This innovative initiative breaks the geographical restrictions of sulfuric acid production management and achieves ubiquitous sulfuric acid production management.

2, technological innovation: Digital sulfuric acid integrates interdisciplinary technology, integrating process, automation, computers, equipment and communication into a whole. Through the application of artificial intelligence technology, research and development and application will become the core driving force to promote the development of digital sulfuric acid.

3, data security: pay attention to the security of internal and external data in the factory, establish and improve data protection mechanisms and measures to ensure the safety of data in the production process.

(4) Summary

In the development, promotion and application of digital sulfuric acid, we face several challenges. For example, there is a lack of case references for cross-domain technology integration, which requires us to make completely new innovations and solve numerous problems. As it involves cross-field technological innovation, we urgently need interdisciplinary talents with new skills. However, problems such as the current lack of talent cultivation require the attention and discussion of the entire industry to find solutions. Eli Lilly is committed to integrating our technological strengths in automation and sulfuric acid processes, and we are committed to developing innovative solutions to address key challenges in the digital economy.
