| 121 | PRODUCTION OF HIGH PURITY SALT WITH REDUCED LEVELS OF IMPURITIES | US14389418 | 2013-04-02 | US20150059129A1 | 2015-03-05 | Pushpito Kumar Ghosh; Sumesh Chandra Upadhyay; Vadakke Puthoor Mohandas; Rahul Jasvantrai Sanghavi; Babulal Rebary |
| The invention discloses an improvement over the existing process of producing solar salt of high purity from seawater and minimizes the need for downstream purification. More particularly, the invention teaches the practical utility of recrystallization of salt in solar salt pans using seawater itself as the dissolving medium. The resultant recrystallized salt is obtained with a yield up to 80% and with much reduced levels of impurities. Special mention is made of the bromide level which is reduced 7-10 fold. The invention is most ideal for trace impurities which reside in the salt crystal lattice and are difficult to dislodge by conventional methods adopted for salt purification and where conventional recrystallization would be cost ineffective and scalability would pose a problem. The invention can be practiced by solar salt works based on seawater and where spare land is available to set up additional crystallizers required for the purpose of recrystallization. | ||||||
| 122 | Recovery of inorganic salt during processing of lignocellulosic feedstocks | US13569308 | 2012-08-08 | US08911979B2 | 2014-12-16 | Brian Foody; Jeffrey S. Tolan; Ziyad Rahme; Vijay Anand |
| A method for recovering inorganic salt during processing of a lignocellulosic feedstock is provided. The method comprises pretreating the lignocellulosic feedstock by adding an acid to the feedstock to produce a pretreated lignocellulosic feedstock. A soluble base is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock. The neutralized feedstock is then enzymatically hydrolyzed to produce an enzyme hydrolyzed feedstock and a sugar stream. Inorganic salt is recovered from either a stream obtained from the lignocellulosic feedstock prior to the step of pretreating, a stream obtained from the pretreated lignocellulosic feedstock, a stream obtained from the neutralized feedstock, a stream obtained from the sugar stream, or a combination of these streams. The inorganic salt may be concentrated, clarified, recovered and purified by crystallization, electrodialysis drying, or agglomeration and granulation, and then used as desired, for example as a fertilizer. | ||||||

| As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur. | ||||||

| A method for inducing chemical reactions using X-ray radiation comprises generating an irradiation volume within the interior of a reaction vessel by introducing X-ray radiation into the volume, in which two or more reactants are introduced. With respect to the two or more reactants and any subsequently created intermediate reactant or reactants, the aggregate extent to which the foregoing reactants are to be ionized to any degree is selectively controlled, and the average degree of ionization in the irradiation volume, from partial to total, of that portion of the foregoing reactants which is to be ionized is selectively controlled, through control of the fluence and energy of the X-ray radiation, to thereby induce selective reactions of reactants to occur in the irradiation volume. One or more reactants may be delivered through a double-walled pipe containing X-ray shielding to prevent their premature irradiation before being injected into the irradiation volume. | ||||||

| A galvanic cell system was discovered that is based on two dissimilar electrodes in an electrolyte solution of hypochlorite and peroxide. The oxidant electrolyte solution contains preferably sodium hypochlorite and hydrogen peroxide in a 10:1 ratio. The cathode (e.g, a copper electrode) was not appreciably consumed. The anode preferably was composed of an aluminum/manganese alloy. This galvanic cell system produced significant current density (e.g., 23 mA/cm2) at a useful voltage (e.g., 1.6-1.7 V/cell). It also produced hydrogen gas, with the maximum production being approximately 1.5 moles of hydrogen per mole of expended anode material. The by-products of this fuel system were environmentally friendly products, including sodium chloride, aluminum hydroxide, and a trace of permanganate ion. | ||||||
