Vista developed a preliminary front-end engineering design (pre-FEED) to integrate flash steam generation (FSG) technology with an existing large scale in-situ heavy oil processing facility.
The Alberta oilsands industry is always looking for new ways to reduce operating costs and improve environmental performance. Seeking to do just that, one of Vista’s long-standing clients partnered with an industrial technology startup to help develop an FSG pilot project.
Vista was hired to complete a pre-FEED level design of how to implement the FSG module at a commercial steam-assisted gravity drainage (SAGD) facility. The current project plan calls for the FSG module to produce 8,300 kg of steam per hour. While this project is still in development, when compared to conventional steam generation and water treatment methods, the projected benefits of this FSG technology include:
- up to 14% GHG emissions reduction
- up to 20% reduction in capital expenditures
- up to 15% reduction in operating expenditures
- up to 95% water recycling
Vista was able to assign a highly effective team of SAGD engineering specialists. The team had many years of combined experience working on several expansion phases at this in-situ heavy oil processing facility.
Given Vista’s familiarity with the client and the facility, the team was able to efficiently deliver a quality fit-for-purpose pre-FEED. As the full-scale FSG unit uses a modular concept, Vista’s leading modularization optimization experience also played an important role in developing this pre-FEED.
Flash Steam Generation Equipment & Technology
The FSG technology is patented by the industrial technology startup and includes:
- including a modular concept
- natural gas heating units
- centrifugal pumps
- multiple-path heat exchangers
- economizer and air pre-heater
The technical knowledge and engineering capabilities demonstrated on this project would also apply in many other industrial processing focused markets.
