As an important pillar of basic chemical raw materials, the chlor alkali industry's products are widely used in various fields such as light industry, chemical industry, textile, metallurgy, and medicine, occupying an irreplaceable strategic position in the national economy. However, this high energy consuming and high emission industry also faces severe environmental pressure and transformation and upgrading challenges. Establishing a comprehensive monitoring system for the chlor alkali industry has become a key measure to ensure the safety of the industrial chain and promote the green and low-carbon development of the industry.

1、 Core dimensions of monitoring in the chlor alkali industry

A comprehensive monitoring of the chlor alkali industry should establish a multidimensional and three-dimensional indicator system. In terms of production and operation monitoring, it is necessary to focus on key indicators such as device operating rate, capacity utilization rate, inventory level, etc. These data can intuitively reflect the industry supply situation and market prosperity. Taking 2022 as an example, the average operating rate of China's chlor alkali industry remains at around 85%, but there are significant regional differences, which provides important reference for optimizing industrial layout. Energy consumption and environmental monitoring focus on core parameters such as comprehensive energy consumption per unit product and compliance rate of three wastes emissions. Currently, the comprehensive energy consumption per unit product of caustic soda in advanced enterprises in China has been reduced to below 320 kilograms of standard coal per ton, but there is still room for improvement in the overall energy efficiency level of the industry. Market dynamic monitoring requires the construction of an indicator system that includes raw salt prices, electricity costs, product prices, import and export volumes, etc. In 2023, due to fluctuations in energy prices, the cost pressure on chlor alkali enterprises will significantly increase. This market fluctuation must be captured and alerted in a timely manner through the monitoring system.

2、 Innovative breakthroughs in monitoring technology system

Modern monitoring technology is reshaping the regulatory model of the chlor alkali industry. The application of Internet of Things technology enables millisecond level collection of operating parameters of key equipment. A large chlor alkali enterprise has increased the accuracy of fault warning to over 98% by deploying more than 2000 sensors in the electrolytic cell. Big data analysis technology can process massive production and operation data. Through mining industry data in the past five years, it was found that the energy consumption level of enterprises in the eastern region is generally 12-15% lower than that in the western region, providing a quantitative basis for industrial transfer policies. It is worth noting that emerging technologies such as satellite remote sensing have begun to be applied in the field of environmental monitoring, which can achieve 24-hour dynamic monitoring of the atmosphere and water environment around chlor alkali enterprises. A certain environmental protection department successfully discovered the problem of unorganized emissions from multiple enterprises through remote sensing technology. These technological innovations are driving a fundamental shift in industry monitoring from regular inspections to real-time monitoring, and from post disposal to pre warning.

3、 The deep application value of monitoring data

High quality monitoring data is generating significant application value. In terms of safety control, by establishing an equipment health evaluation model, a certain enterprise has reduced unplanned parking frequency by 70%, resulting in an annual economic loss reduction of over 100 million yuan. In terms of energy efficiency optimization, an intelligent control system based on real-time monitoring data can reduce the electricity consumption of the electrolysis unit by 3-5%. According to the industry's annual production of 40 million tons of caustic soda, the annual energy savings can reach 2.4-4 billion kilowatt hours. More importantly, monitoring data is becoming the scientific support for policy-making. The setting of multiple energy efficiency indicators in the "Implementation Guidelines for Energy Conservation, Carbon Reduction, and Upgrading of Chlor Alkali Industry" is based on the analysis and judgment of continuous monitoring data from hundreds of enterprises. Under the "dual carbon" goal, these data will also provide basic support for industry carbon emission accounting and carbon footprint tracking.

4、 The future direction of monitoring system construction

Facing future development, the monitoring system of the chlor alkali industry needs to achieve three upgrades: extending from single production monitoring to full lifecycle monitoring, covering the entire chain from raw material procurement to product application; Expanding from domestic monitoring to global monitoring, establishing an early warning mechanism to address international trade frictions; Upgrade from data collection to intelligent decision-making and develop monitoring and early warning models with industry characteristics. Especially in the context of green and low-carbon transformation, it is necessary to accelerate the establishment of a comprehensive environmental performance evaluation system that covers carbon emissions.

The improvement of the monitoring system in the chlor alkali industry is not only related to the operational efficiency of individual enterprises, but also an important measure to ensure the safety of the national basic chemical industry chain. With the continuous advancement of monitoring technology and the deepening of data applications, this system will inevitably become an important engine for promoting high-quality development of the industry, providing solid support for building a safe, efficient, and green modern chemical industry system. In the future, it is necessary for the government, enterprises, and research institutions to collaborate and jointly create a new intelligent monitoring ecosystem for the chlor alkali industry that adapts to the new development pattern.
