| Abstract:This paper focuses on the automation instrumentation project of a bleached chemical pulp technical renovation initiative, conducting in-depth analysis of typical issues in modern industrial automation instrumentation engineering across design management, installation & commissioning, and equipment selection. Through empirical research, key challenges are identified including design drawing accuracy, instrumentation type compatibility, and control system integration, leading to the innovative development of a "Three-Dimensional Collaborative Management Model". The project has also established technical management methodologies such as the "Five-Step DCS Renovation Methodology" and "Three-Verification Principle for Valve Selection", providing critical references for similar engineering projects. Research data demonstrates that through comprehensive optimization management, the project achieves: 37% reduction in rework rate, 42% shortening of commissioning cycle, and 65% decrease in equipment failure rate, effectively advancing the development of automation instrumentation engineering in the pulp and paper industry. |
