An aqueous organ preservation solution includes taurine and L-alanine-L-glutamine and glutamic acid. The organ preservation composition can be stored in a solid state, for example in the form of small particles (e.g. a powder or micronized powder), and be dissolved in water, thereby instantly providing a ready-to-use organ preservation solution.

The present invention relates to processes employing water produced from wells that, after suitable purification steps, is processed to recover resources that can be used to treat other waste streams, such as flue gases and ashes from combustion of fossil fuels.

The present invention provides a method for treating a gas, comprising: step (A): collecting a gas comprising carbon dioxide and fine particulate matter; step (B): rinsing the gas with water to obtain a rinsed gas; and step (C): contacting the rinsed gas with a basic solution in a way of co-current flow to absorb the carbon dioxide in the rinsed gas by the basic solution to obtain a treated gas and a weak basic solution; wherein the pH value of the basic solution is between 9 and 14, and the pH value of the weak basic solution is between 8 and 8.5. The method can reduce the content of both fine particulate matter and carbon dioxide.

Waste water is treated by contacting it with sodium to form hydrogen which is then contacted with air in a combustion chamber to produce clean water and heat.

Process for the joint production of sodium carbonate and sodium bicarbonate crystals, according to which: a solid powder derived from sodium sesquicarbonate, having a mean particle diameter comprised between 0.1 and 10 mm is dissolved in water; the resulting water solution is introduced into a crystallizer, wherein a first water suspension comprising sodium carbonate crystals is produced; the first water suspension is subjected to a separation, in order to produce crystals comprising sodium carbonate on the one hand, which are valorized, and a mother liquor on the other hand; and a part of the mother liquor is taken out of the crystallizer and put into contact in, a gas liquid contactor, with a gas comprising carbon dioxide, in order to produce a second water suspension comprising sodium bicarbonate crystals, which are separated and valorized. A reagent powder comprising sodium bicarbonate crystals made by such process.
