Refining By Water Treatment TRIZ Cases
- GOSP Crude Oil Quality Control Using Virtual Parameters
Virtual parameters and a feedback loop predict and improve GOSP crude oil quality while reducing reliance on complex online instruments.
- Hydroprocessing Wash Water Recycling to Recover Oxygenate Yield
Recycled wash water saturated with oxygenates cuts product loss during partial hydroprocessing and preserves hydrocarbon fuel yield.
- Oil-Miscible Mercury Removal Additives for Liquid Hydrocarbons
An oil-miscible sulfur-donor additive changes mercury speciation in liquid hydrocarbons, enabling easier separation with lower cost and energy use.
- Residue Upgrading with SDA Resin Separation and SCW Treatment
Separating residue into DAO, resin, and pitch lets SCW upgrade resin before mild hydroprocessing, raising liquid yield and cutting low-value pitch.
- Hydrotreatment Separation of Halide Feedstocks Without Ammonium Salt Fouling
A two-step hot separation with wash water removes halides and ammonia from hydrotreated feedstocks while avoiding ammonium halide blockage and corrosion.
- Desalter Water Reuse Using Compressor Waste Heat Evaporation
Waste heat from compressed gas evaporates high-TDS desalter effluent, producing low-salinity wash water for closed-loop crude oil desalting.
- Halide-Free Hydrocarbon Production Through Pressure Separation
High-pressure gas/liquid separation and low-pressure steam stripping produce purer hydrocarbons while reducing water use and corrosion risk.
- Solvent Deasphalting for Heavy Oil Viscosity Reduction
Integrating solvent extraction with water removal eliminates front-end desalting units, reducing capital investment and operating expenses.
- Hydrocarbon Upgrading via Supercritical Water and Hydrogen Donor
Supercritical water and a hydrogen donor upgrade hydrocarbons in a catalyst-free reactor, eliminating external hydrogen needs and reducing coke formation.
- Steam Injection Crude Oil Desalting Process
Condensing steam bubbles dissolve salt in crude oil and enlarge brine droplets, reducing pumping energy consumption and settling time.
- Two-Stage Hydrotreating Process with Interstage Separation
Injecting water into residue feed and separating hydrogen sulfide between stages.
- Supercritical Water Hydrogenation for Heavy Oil Stability
Hydrogen addition saturates heavy hydrocarbon radicals in supercritical water reactors, preventing gum and coke formation during thermal cracking.
- Sequential Mixing for Crude Oil Desalting
Segmented mixing stages create fine emulsions for salt transfer then optimize droplet size, improving desalting efficiency in heavy crude processing.
- Microwave Desulfurization of Crude Oil Using Phosphoric Acid Ester
Phosphoric acid ester extracts sulfur compounds via microwave heating, eliminating high-pressure hydrogen requirements and catalyst deactivation.
- Salt Analyzer for Crude Oil Using Process Parameter Model
A salt analyzer calculates crude oil salinity from desalting process parameters.
- Refining Used Electrical Insulating Oils via Vacuum Degassing
Vacuum degassing under reduced pressure removes volatile sulphur compounds from used electrical insulating oils, preventing oxidation and corrosivity.
- Magnetized Oxygen MNB Water Treatment for Heavy Crude Oil Recovery
Magnetized oxygen micro nano bubble water depolarizes asphaltenes into resins, resolving incomplete bitumen recovery caused by cohesive film formation.
