A produced water stream in a GOSP is pretreated to remove total suspended solids, emulsified oil, total organic carbon, chemical organics and inorganics, and biodegradable matter. The pretreated produced water stream is further processed to remove hydrogen sulfide gas, which is split in an electrolysis cell to produce hydrogen, sulfur, and water. Following this, bromine gas is removed. The pretreated produced water stream, after the removal of hydrogen sulfide and bromine gas, is further treated using CO2 to produce several minerals. The pretreated produced water stream, after mineral production, is desalinated to produce fresh water and a reject stream. Several valuable chemicals are produced from the reject stream. This process recovers valuable minerals and chemicals from a produced water stream in a GOSP.

A hydrogen generation system with controlled water distribution is disclosed. The system comprises a reaction chamber containing a hydrogen-producing fuel, a liquid distribution mechanism, and a control system. The liquid distribution mechanism includes a rotating arm with liquid injection ports that move vertically through the fuel chamber. This allows for precise and efficient liquid delivery to unreacted fuel, optimizing hydrogen production. A proprietary fuel blend utilizes chemicals that store significant amounts of hydrogen in a solid-state form. A feature of the device is the arm's controlled vertical movement, achieved through a screw mechanism that adjusts the arm's height as it rotates, creating a spiral liquid distribution pattern. The control system regulates liquid injection rates, arm rotation speed, and vertical movement to optimize hydrogen production based on demand. The system can also operate at low pressures and be scaled to different sizes in a safer, more efficient, on-demand manner.
