PRODUCED WATER TREATMENT FOR DIRECT INJECTION USING MECHANICALLY ASSISTED FORWARD OSMOSIS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18048608 titled 'PRODUCED WATER TREATMENT FOR DIRECT INJECTION USING MECHANICALLY ASSISTED FORWARD OSMOSIS
The disclosure of this patent application involves a method that includes pre-treating a high salinity aqueous liquid to remove solids, oils, and dissolved gases. The pre-treated liquid is then used as a draw solution for mechanically assisted forward osmosis to produce injection water, which is subsequently injected into an underground formation. The high salinity aqueous liquid can be produced water or ground water, and the draw solution is diluted with a feed solution that has a lower osmotic pressure than the high salinity aqueous liquid.
- The method involves pre-treating high salinity aqueous liquid to remove impurities before using it as a draw solution for forward osmosis.
- The innovation allows for the production of injection water for underground formations using a more efficient and environmentally friendly process.
- By diluting the draw solution with a feed solution of lower osmotic pressure, the method optimizes the osmotic process for water injection.
- This technology can be applied in various industries such as oil and gas, water treatment, and environmental remediation.
Potential Applications: - Oil and gas industry for water injection in reservoirs - Water treatment plants for purifying high salinity water - Environmental remediation projects for injecting treated water into contaminated sites
Problems Solved: - Efficient removal of impurities from high salinity aqueous liquid - Production of injection water for underground formations using forward osmosis - Optimization of osmotic processes for water injection
Benefits: - Reduced environmental impact compared to traditional water injection methods - Cost-effective treatment of high salinity water - Improved efficiency in water treatment processes
Commercial Applications: Title: Innovative Water Treatment Technology for Underground Injection This technology can be utilized in the oil and gas industry for enhanced oil recovery operations, as well as in water treatment plants and environmental cleanup projects. The market implications include increased efficiency, cost savings, and environmental compliance.
Prior Art: There is prior art related to forward osmosis processes for water treatment and desalination, but the specific application of using pre-treated high salinity aqueous liquid as a draw solution for injection water production in underground formations may be novel.
Frequently Updated Research: Research on forward osmosis processes, water treatment technologies, and underground water injection methods is continually evolving. Stay updated on the latest advancements in these fields to enhance the application of this technology.
Questions about the Innovative Water Treatment Technology for Underground Injection:
Question 1: How does this technology compare to traditional water treatment methods in terms of efficiency and cost-effectiveness? Answer: This technology offers improved efficiency and cost savings compared to traditional methods by utilizing forward osmosis and pre-treated high salinity aqueous liquid as a draw solution for injection water production.
Question 2: What are the potential environmental benefits of using this technology for underground water injection?
