Subsequently, there is the reaction of the water with reagents in a reactor. In the reaction step, inside the reactor, the osmotized water enters from a first orifice (C) via a solenoid valve with micrometric regulation (EV1). Inside the same reactor, the base chemical products enter via the respective orifices A and B. The base chemical products enter due to the action of metering pumps (e.g. peristaltic pumps).

  • Patent number: 9713788
    Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios>0.5:1 (approaching 1:1) may be achieved.

  • Patent number: 9327309
    Abstract: Processes for recovering inorganic powder materials from polymer-based coating compositions used to deposit a polymer-based coating. The process includes combining a polymer precursor, first solvent, and inorganic powder material to form a suspension, and applying the suspension to a substrate to form a layer. At least a portion of the suspension that did not adhere to the substrate is then collected. Residual portions of the first solvent and polymer precursor are at least partially removed from this portion of the suspension to yield a crude inorganic powder material comprising a residual portion of the inorganic powder and optionally a partially-cured polymer precursor, the latter of which can be removed by treating the crude inorganic powder material with a second solvent.

  • Patent number: 9180411
    Abstract: The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature, followed by any of membrane distillation or forward osmosis (FO), may be combined with a subsequent process of ceramic ultra-filtration (UF filtration) employed to treat water. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.
