Acid Growth 2 – Acid and Caustic Railcar Loading Capacity Increase

Canexus Corporation
North Vancouver, British Columbia
Project Year: 2011/2012

The Canexus Chemicals facility in North Vancouver, BC has expanded their Hydrochloric Acid production facilities requiring an increase to the railcar loading capacity. Canexus engaged MG Engineering to upgrade their acid and caustic rail loading facilities. The project consisted of feasibility, appropriation budget preparation and detailed engineering for three new acid railcar loading stations and three new caustic railcar loading stations. The scope of the work included the support structure complete with access gangways, fall protection cages, sumps, pumps and spill containment.

The project included:
  • Structural engineering of the new stations including foundations, platforms, roof, support steel and stairways.
  • Mechanical engineering including detailed piping design, general arrangement drawings, equipment selection and specification.
  • Process engineering including process concept development, HAZOP participation and control narrative preparation.
  • Development and maintenance of the engineering, procurement and construction schedule.
  • Procurement assistance included the specification of equipment, piping and steel, along with request for quotation, comparison of bids and preparation of purchasing and tender documents.
  • The engineering and construction was unique since the implementation plan had to maintain the existing loading facility operations during the construction of the new loading stations.
MG Engineering prepared a feasibility and appropriation budget estimate for the project in 2011 and was awarded the detailed engineering in 2012. Construction began in the summer of 2012 and will be completed in Q2 2013.

MG celebrates with Canexus the successful start up of the new facility which is meeting expectations for acid and caustic loading rates. The new facility has also achieved significant safety and environmental improvements.
