Jiangxi Lihua Chemical’s caustic soda digital workshop passed the company’s acceptance review

Thread Content

On the 6th of the month, members of the technical evaluation committee of Jiangxi Lihua Culture and Industry Co., Ltd. conducted a systematic acceptance review of the company’s digitalization project for its caustic soda production facility. This acceptance was carried out in accordance with the requirements of the \"Four Standards and One Plan,\" adhering to the principle of \"practicality, effectiveness, and suitability for use,\" in order to comprehensively assess the practicality and effectiveness of the construction of the digital caustic soda workshop. 　　After comprehensive evaluation by the review committee, it was unanimously agreed that the current caustic soda production facility has reached an industry-leading level in terms of automation control, data interoperability, and full traceability throughout the production process. In particular, the digital transformation of the electrolysis process serves as a significant benchmark for the industry. And it passed the acceptance inspection for the caustic soda digital workshop project. 　　Standard leadership: Proactively aligning with standards to outline a vision. On November 27, 2024, Jiangxi Lihua Chemical Industry initiated an internal benchmarking and diagnosis process for its digital caustic soda production facility, based on the \"Guidelines for the Construction of Digital Workshops in the Chlor-alkali Industry – Electrolysis\" (a standard in draft form at that time). Yang Zuoning, the company’s general manager, took personal charge of leading the efforts related to meeting these standards; he organized the company’s technical experts to thoroughly analyze the content of those standards, identifying 8 areas that needed improvement. On December 25, 2024, the company officially released the \"Digital Workshop Construction Plan for Caustic Soda\", clearly proposing to create a digital workshop for caustic soda through three key measures: hardware upgrades, software enhancements, and platform development. 　　It is reported that to ensure the smooth progress of the construction of a digital caustic soda workshop, Jiangxi Lihua Chemical Industry has also adopted an innovative approach: self-practice and process reengineering. 　　On the one hand, strengthen the security foundation through hardware upgrades. High-precision flow meters and intelligent control valves have been installed to enable precise management of production parameters; online density meters and the APC advanced process control system have been added, which significantly improves the accuracy and stability of control over key process parameters and enhances intrinsic safety. 　　On the other hand, optimize production operations through software empowerment. A programmable system for \"one-click load adjustment\" of electrolyzers has been developed, which significantly reduces the response time for current regulation and improves production stability ； Apply the intelligent automatic switching program for pump unit failures to improve the reliability of equipment operation ； Logical coverage analysis is conducted using online instrument data, enabling quality prediction after half a year of trial operation. 　　Secondly, it is to drive intelligent decision-making through digital platforms. A \"digital cockpit\" has been developed, integrating functions such as real-time production data, equipment operation parameters, energy and carbon data, as well as safety and environmental monitoring, thereby enabling visualized control over the entire process of caustic soda production. The predictive maintenance and optimization control model based on big data analysis has been put into use, resulting in a significant improvement in production efficiency. 　　In his summary of the inspection, Yang Zuoning emphasized that this compliance inspection represents an important milestone in the company’s journey toward digitalization in the production of caustic soda, and it serves as a new starting point for further advancing its intelligent transformation. In the future, Jiangxi Liwen Culture & Technology must be brave enough to break free from fixed mindsets and path dependencies, adhere to a pragmatic approach, take proactive actions, understand underlying mechanisms, develop appropriate systems, and blaze new paths. It should further expand the development of digital applications within the company, fully exploit the potential value of industrial big data, and contribute to the digital transformation of the industry.
