ICI Halochemicals has placed an order worth £500,000 with Fisher-Rosemount for the liquid chlorine manufacture (LCM) project at Runcorn. The order involves the replacement of existing single loop controllers and manual control operations with a scaleable DeltaV process control system. It will embrace the PlantWeb field-based architecture and Foundation fieldbus devices. These components take the form of H1 cards that mounts alongside standard I/O modules.

The project is part of the Close Alliance Partnership between ICI Halochemicals and Fisher-Rosemount, where the latter act as a complete process automation partner, rather than a conventional supplier. It is the fifth project to have been ordered under the Alliance agreement, the other four systems having already been implemented, installed and are now operational.

Liquid chlorine manufacture is a critical process, since it is one of the primary upstream plants on the Runcorn site. A high degree of reliability is essential as the plant does not have any planned shutdowns.

Fisher-Rosemount is also supplying field equipment for the project in the initial and subsequent phases. With a guaranteed stability of 0.125% over a five year period, Model 3051 pressure transmitters will be used for these critical duties.
