Dynamic Simulation Assured Smooth Upgrades of Obsolete Bleach Line Control Equipment, 1997 Pulping Conference Proceedings
Through the use of dynamic simulation, the design of modern control systems to replace existing obsolete equipment is enhanced. The risks associated with the commissioning of the upgraded control system are greatly reduced. Personal computers coupled with a new generation of dynamic simulation software make it possible to design and test complete control strategies reliably and inexpensively.
Union Camp Corporation Franklin, Virginia mill, used PC-based dynamic simulations on two bleach line upgrade projects. The simulator played a major role in verifying Distributed Control System (DCS) and Programmable Logic Controller (PLC) configurations and in providing operator training prior to the bleach line commissioning of controls. The bleach lines started up with almost no configuration modifications other than loop tunings. Upon completion, both lines achieved higher production with significantly better quality pulp.
