Multiport Valve Replacement
  |
Allnorth Consultants was retained to provide detailed engineering and design services for the replacement of a 50 year old multiport valve at the Pulp and Paper Mill in Crofton. The valve was installed on their No. 3 Anion unit that was provided as part of the original demineralizer system. The existing rubber lined and plastic pipelines that connect to the multiport valves were replaced inkind and reconfigured to accommodate a group of new, single-port diaphragm valves. The piping around the multiport valves is highly congested and includes multiple instruments. In an effort to minimize the shut-down time required to make the modifications, we used our 3D laser scanner to scan the in-situ piping system. During the scan of the No. 3 Anion, the equipment and piping at No. 1 & 2 Anions was also collected. By using the scanner we were able to eliminate the need for field joints and thereby kept the shutdown time to a minimum.
In 2007 we were retained to provide the detailed engineering and design services for the piping modifications to the No. 3 Cation. We were able to re-use the scan data collected in 2006 to complete this design at a lower cost and in less time.
