“…The proposed separation process is carried out for highly-saline water (brine) using a non-conventional partial desalting method [12][13][14]. The method utilizes a series of chemical reactions involving the conversion of sodium chloride, the major constituent in saline waters, into sodium bicarbonate and ammonium chloride soluble in partially desalted water making what is called "fertile water".…”

This paper presents a novel approach for desert development, taking the Arab countries a model in our study. Solutions to make the most from the sun to turn our desert into useful and arable land are proposed. Saline water resources from sea or rejects from desalination plants (brines) are chemically processed to produce partially desalted water along with valuable chemical products. Solar hydrogen is a cornerstone in our system to produce ammonia, which has dual functions in the scheme. Ammonia represents a source of nitrogen for plants. It is used together with carbon dioxide in the chemical separation process of saline water. For the Arab countries with an average solar intensity flux = 700 Watt/m 2 , an average sunshine hours of 3000 annually and only 1% of total land area for solar power generation, it is feasible to produce the equivalent of 184 × 106 tons of hydrogen yearly by water electrolysis. Ammonia gas synthesis takes place, using solar hydrogen and atmospheric nitrogen. Experimental findings are reported by the author and co-workers. Separation of salt brine (from inland sources or from the sea) was carried out in a gas bubbler using a modified Solvay process to study the conversion of sodium chloride into chemical products (namely sodium carbonate and ammonium chloride). The highest conversion achieved of sodium chloride was 82.2%, and the balance makes partially desalted water. Magnesium chloride is obtained as a by-product. The role of hydrogen as a vector coupled with solar energy for desert development is schematically illustrated.

“…This investigation applies a novel method for transforming saline water, which is discharged or rejected from an oil and gas field into useful irrigation water and soda ash compounds (Na 2 CO 3 ) . For areas such as the Gulf regions, this is considered to be a well‐known problem, which has been under investigation for a long time in search of a solution using already accessible material, such as the existing CO 2 and saline water .…”

Simultaneous removal of CO₂ and salts from saline water by a combined process

The emission of CO2 has been increasing steadily and with the increasing demand of desalinated water (especially in Gulf Cooperation Council countries) this is expected to increase at a faster rate. CO2 removal from sour natural gas, from the water desalination power plants and similar sources is important not only to these industries but also to reduce the effect on global warming. In this study, a simple process is investigated experimentally to remove CO2 from a synthetic mixture of natural gas containing it. The method is based on the modified Solvay process and involves the chemical reaction between CO2 and ammonia in saline solution. The process can reduce CO2 by about 99% and at the same time reduce water salinity by 40%. The process is potentially much more effective than the amine scrubbing process, without the operational problems for environmental damage posed by monoethanolamine organic compounds. The innovative process shows the technical feasibility of sweetening natural gas in the laboratory‐scale operation. It can also be applied to the removal of CO2 from polluting sources like car exhaust. Simultaneous reduction of salinity is additional benefit of this process. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 250–256, 2016
