Vista’s client operates a large Steam Assisted Gravity Drainage project where inlet water chemistry to the warm lime softener was going to be changing as a result of using produced water/blowdown from the pilot plant in the short term, and future plans to use saline water as makeup for the water lime softener. Due to the change in salinity in the inlet water, the client’s water treatment specialists and coordinators identified the need to install a soda ash storage and delivery facility. Vista’s detailed engineering and procurement analysis recommended installing an automated soda ash storage and delivery system that is similar to the existing lime and MagOx packages.
The initial soda ash package (complete with foundation, structural supports, piping, electrical instrumentation and control system tie-ins), was initially purchased and completed by the client, using a template from another facility. The soda ash package vendor provided substandard engineering quality with insufficient and incorrect information on drawings and datasheets. Vista provided technical expertise and guidance to correct and update the vendor information to a level sufficient for construction. Vista then completed a drawing and data consolidation, redrafting the vendor drawings and creating new datasheets.
Vista’s attention to detail and expediting of the vendor skid limited the extent of delay and rework. With Vista’s experience in water treatment, the tie-in locations for feed water and soda ash slurry were optimized to enhance the effectiveness of the chemical addition.
