Nantong Cellulose chooses Emerson for fourth automation project
Expansion of the cellulose acetate recycle area is a major part of this project that will add two cellulose acetate recycling units, two cellulose acetate production units, a filter unit for diluted acid, a configuration unit for mixed acids, a chemicals configuration unit, a tank farm at the unloading pier, and other related equipment. All construction is expected to be finished by April 2007.
Emerson has a record of success with Nantong Cellulose, beginning with initial automation with Emerson's RS3 control system. Next, Emerson successfully implemented phase two and phase three projects that upgraded from RS3 systems to the DeltaV(TM) digital automation system. This fourth project includes implementing an open, standard data communications bus that enables system control, monitoring, and process or other data updating capabilities. The digital communications also supports data analysis, statistics, calculation, event triggering, software development, and other functions.
Use of AMS Device Manager enables Nantong Cellulose to continuously monitor field devices from the maintenance shop or control room. Since the diagnostic functions of PlantWeb architecture enable users to find potential problems before they become issues, the new architecture will improve maintenance efficiency, avoiding conditions that could cause serious downtime, and will reduce trips to the field along with associated costs and risks to personnel.
