Abstract
Oil sands process water (OSPW) is directed to an evaporator that evaporates the OSPW and produces steam and a concentrated brine. The OSPW includes alkalinity and calcium hardness. To inhibit calcium carbonate scaling of the evaporator, magnesium oxide is mixed with the OSPW, resulting in the precipitation of magnesium hydroxide which acts as a seed material for calcium carbonate precipitation to prevent fouling. The process crystallizes the calcium carbonate and the mixture of magnesium hydroxide and calcium carbonate crystals are circulated through the evaporator as well as recirculated to a point upstream of the evaporator.
