||PCT/CA2015/050470||SRO TECH CORPORATION ||WONG, Wing-Yam |
The invention relates to a biofilm growth system comprising a rack with at least two horizontal panel layers mounted on said rack, inlet and outlet manifolds and a holding tank connected to said inlet manifold. The biofilm growth system further comprises a harvest system comprising a spring loaded blade for scraping algae from said horizontal panel layers and a vacuum means in association with the spring loaded blade. The biofilm growth system is for use in growing biofilm generating organisms such as algae. Said biofilms are able to remove impurities from wastewater that has been obtained from water and/or sewage treatment facilities. The biofilm growth system is additionally designed to use flue gas as a C02 source to increase biofilm growth on said horizontal panel layers.

||PCT/EP2015/060923||SOLVAY SA ||PERRIN, Patrick |
This application concerns a process for producing a calcium phosphate reactant, according to which: - in a first step, use is made of a source of calcium and a source of phosphate ions in water, in a molar ratio that is adjusted so as to obtain a Ca/P molar ratio of between 0.5 and 1.6, and the source of calcium is reacted with the phosphate ions at a pH of between 2 and 8, in order to obtain a suspension (A) of calcium phosphate, and • - in a second step, added to the suspension (A) are an alkaline compound comprising hydroxide ions in order to set a pH of more than 8 and an additional source of calcium in order to obtain a suspension (B) of calcium phosphate reactant having a Ca/P molar ratio of more than 1.6. Further, the application concerns a method for purifying a liquid effluent containing metallic elements and or non/metallic elements with the calcium phosphate reactant obtainable by this process.

||13915883||L'Air Liquide, Société Anonyme pour l'Étude et l'Éxploitation des Procédés Georges Claude||Bhadra S. Grover|
An apparatus for producing hydrogen from an off-gas originating from a gas to liquid (GTL) process is provided. The apparatus includes a cryogenic distillation column, a first CO shift reactor, a second CO shift reactor, an SMR, and a first and second PSA. The cryogenic distillation column is configured to receive an off-gas and separate it into a light ends and a heavy ends. The first CO shift reactor is configured to receive the light ends and, in the presence of steam, produce additional hydrogen and carbon monoxide. The SMR is configured to receive the heavy ends and convert hydrocarbons within the heavy ends to hydrogen and CO, with the resulting stream then being treated in the second CO shift reactor to produce additional hydrogen and CO2. The hydrogen is then captured using the first and second PSAs.
