Abstract：Thisstudyfocusedontheautomationinstrumentationprojectwithinableachedchemicalpulptechnicalrenovationinitiative，providinganin-depthanalysisoftypicalchalengesinmodernindustrialautomationinstrumentationengineeingacross key phases suchasdesign management，installtionandcommissioning，and equipment selection.Through empiricalresearch，core conflicts includingdesigndrawingacuracy，instrumentselectioncompatibility，andcontrolsyste integrationweresysteaticaly identified.Aninnovative“Three-dimensionalCollaborativeManagementModel”wasproposed.Additionall，technicalmanagementmethodologiesdevelopedduring projectimplementation，suchasthe“Five-stepDCSRenovationMethod”and“Three-verificationPrincipleforValveSelection”，oferedcriticalreferencesforanalogousprojects.Researchdatademonstratedthatcomprehensive optimization management could reduce project rework rates by 37% ，shorten commissioning cycles by 42% ，and decreased equipment failure rates by 65% ，thereby strongly advancing the development of automation instrumentation engineering in the pulp and paper industry.
