A Canadian oil refinery will soon reuse 100 percent of its water with help from General Electric wastewater treatment technology.
Federated Co-Operatives Limited’s Co-op Refinery Complex in Regina, Saskatchewan, Canada, is installing GE’s water recycling technology. The wastewater improvement project will enable the refinery to clean all of its wastewater on-site.
Once fully operationally, the Co-op Refinery Complex will be the only refinery in North America to recycle 100 percent of its wastewater for steam production, which is used for heating, hydrogen production, to power equipment and for cooling towers, GE says.
Several years ago the refinery expanded its operations to produce 30,000 more barrels of oil per day (BPD) taking it from 100,000 BPD to a 130,000-BPD facility, which increased its water usage. The refinery’s current water source is a blend of well water and city water, and restrictions on water use mandated that the Co-op Refinery Complex had to find a new source of water.
GE’s solution combines its ZeeWeed membrane bioreactor technology and a high-efficiency reverse osmosis system to recycle and reuse 2 million gallons of wastewater a day.
In addition to the water reuse solution, GE will provide the refinery with wastewater specialty chemicals and monitoring systems to help optimize the process.
After commissioning, the refinery will reduce its use of freshwater by 28 percent. The wastewater improvement project is expected to be fully operational by the fall.
In China, a coal-to-chemical facility is using GE wastewater treatment technology to meet new environmental regulations and enable water reuse. GE’s zero liquid discharge evaporator and crystallizer system eliminates liquid discharge of waste and enables water reuse at the Shaanxi Future Energy Chemical Co. coal-to-chemical plant in Shaanxi Province.
