Recovery of 3-hydroxypropionic acid
A method for recovering a composition enriched in 3-hydroxypropionic acid by providing the fermentation broth, acidifying the fermentation broth; reducing the total sulfate ion and phosphate ion concentration of the resulting aqueous solution to produce a reduced ion aqueous solution; distilling the resulting reduced ion aqueous solution and recovering the resulting aqueous distillation product comprising 3-hydroxypropionic acid.
System and method for removal of water from oil
A system and method for removing water from oil comprises: a housing, an oil inlet tube fluidly connecting the oil supply and an oil inlet of the housing, an inlet pump configured to pump a flow of oil from the oil supply to the oil inlet at a first pumping flow rate, an oil outlet tube fluidly connecting an oil outlet of the housing and the oil supply, an outlet pump adapted to pump a flow of oil from the oil outlet to the oil supply at a second pumping flow rate, an air inlet tube providing a gas connection between a air supply unit and an air inlet of the housing, and an air outlet tube providing a gas connection between an air outlet of the housing and the air supply unit, wherein the second pumping flow rate is greater than the first pumping flow rate
Method for Producing Refined Chlorosilane
A method for producing purified chlorosilanes includes bringing crude chlorosilanes, such as crude trichlorosilane and crude silicon tetrachloride, which contain a boron compound and/or a phosphorus compound, into contact with chlorine (preferably 1 ppm mole to 3000 ppm mole with respect to 1 mole of crude chlorosilanes) in presence of alkylphenol such as 2-methylphenol, and then distilling the crude chlorosilanes.
Catalytic hydrodearylation of heavy aromatic streams containing dissolved hydrogen with fractionation
Systems and methods for hydrodearylation of a hydrocarbon feed stream comprising non-condensed alkyl-bridged multi-aromatic hydrocarbons, the method including supplying a hydrogen feed to the hydrocarbon feed stream comprising non-condensed alkyl-bridged multi-aromatic hydrocarbons; mixing the hydrogen feed with the hydrocarbon feed stream to saturate the hydrocarbon feed stream with hydrogen gas to create a hydrogen-enriched liquid hydrocarbon stream; passing the hydrogen-enriched liquid hydrocarbon stream to a hydrodearylation reactor without a separate gaseous phase of hydrogen; allowing the hydrogen-enriched liquid hydrocarbon stream to react in presence of a catalyst under specific reaction conditions to produce a product stream comprising a reduced concentration of di-aromatic compounds and an increased concentration of mono-aromatic compounds compared to the hydrocarbon feed stream comprising non-condensed alkyl-bridged multi-aromatic hydrocarbons; and recovering, from the hydrodearylation reactor, a product stream for a downstream process, wherein the non-condensed alkyl-bridged multi-aromatic hydrocarbons include at least two benzene rings connected by an alkyl bridge group having at least two carbons, wherein the benzene rings are connected to different carbons of the alkyl bridge group.
SEPARATION OF SULFUROUS MATERIALS
The present disclosure relates to systems and methods for separation of sulfurous material(s) from a multi-component feed stream. The systems and methods can comprise contacting the multi-component feed stream with a solvent in a contacting column so that at least a portion of the sulfurous material(s) is transferred from the multi-component feed stream to the solvent. A stream of a substantially purified gas can thus be provided along with a liquid stream comprising at least a majority of the sulfurous material. In particular, the solvent can comprise liquid carbon dioxide, which can be particularly beneficial for removing sulfurous materials from multi-component feed streams.

DISAGGREGATION OF BIOMASS PYROLYSIS OIL
Described is a novel process for disaggregating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction (HAF), fermentable pyrolytic sugars and phenolics based products in a highly economical and energy efficient manner. Phase separation of the esterified pyrolysis oil after an oxidative pre-treatment and the quantitative recovery of the separate fractions is described. Phase separation uses batch as well as continuous reactor systems. The resulting HAF is an energy dense, thermally stable, water free, non-corrosive to carbon steel, and is a free flowing liquid suitable for combustion and for upgrading to transportation fuels. Pyrolytic sugars which are mainly anhydrosugars can be further converted by fermentation to ethanol or other products. Monomeric phenols are useful industrial intermediates and the organic acids in the original pyrolysis oil are mainly recovered as esters of the separation solvents.
