A system and process for concentrating a lithium stream is disclosed. The lithium stream is directed to a reverse osmosis unit which produces a concentrate containing lithium compounds. The RO concentrate is directed through two pressure retarded osmosis (PRO) modules connected in series. The two PRO modules further concentrate the RO concentrate and at the same time yield a diluted brine that is effective to drive an energy recovery device. The RO concentrate leaving the PRO modules is directed to an osmotically assisted reverse osmosis (OARO) module which also further concentrates the RO concentrate.

A natural gas processing system is mounted on a mobile platform that is transported to a natural gas source, such as a well. The system supplies retentate gas to operate multi-fuel engines for wellfield equipment such as pumps, compressors, and drills. A liquid drain discharges contaminants. A separator, first and second coalescing filters, and a particulate filter remove particulate matter and fluid contaminant matter from the natural gas. A dryer removes water vapor from the natural gas. Dual membranes separate the natural gas into a retentate gas and a permeate gas. A first heat exchanger adjusts temperature of the natural gas entering the membranes. A second heat exchanger adjusts temperature of the retentate gas output. A thermoelectric generator powered by the natural gas supplies process electricity. A process control monitors and controls the natural gas processing system, including pressure control valves, temperature control valves, and emergency shutdown systems. An instrument gas supply with an accumulator supplies gas pressure to operate pneumatic valves and instruments.

This method, for regenerating a member used in a device that treats seawater, involves a cleaning step for removing deposits from the member. In the cleaning step, a first chemical solution containing an acid other than hydroxydicarboxylic acid and a second chemical solution containing hydrogen peroxide, a heavy metal compound and hydroxydicarboxylic acid are used.
