There is provided a method for producing, at a high yield, a composition containing 3-chloro-4-methoxybenzylamine hydrochloride (CMBA-HCl) in which the purity of CMBA-HCl is high. This method comprises a chlorination step involving a chlorination reaction that generates CMBA-HCl from 4-methoxybenzylamine hydrochloride using hydrogen peroxide and hydrochloric acid. There is also provided a CMBA-HCl-containing composition which is produced by the aforementioned production method and in which the purity of CMBA-HCl is high.

Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.


A vinylbenzylated phenol compound represented by General Formula (1) below is provided. (In General Formula (1), Ar^(0 )is a bifunctional phenol compound residue having one or more monocyclic or polycyclic aromatic nuclei, R^(1 )to R^(5 )may be the same or different and are each hydrogen or a methyl group, and p is an integer of 1 to 4.)

An intake screen assembly including an intake member, a screen support member, and a screen member coupled to the screen support member. The screen member may be formed from a material, such as copper-nickel, that is different from a material, such as stainless steel, used to form the intake member and/or the screen support member. The intake screen assembly may include corrosion protection members for preventing contact between the components of the screen assembly that are formed from dissimilar materials. The assembly may be formed by coupling the screen support member to the intake member, and coupling the screen member to the screen support member.

The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.


There are provided a method for purifying a hydrogen gas and an apparatus for purifying a hydrogen gas, which are capable of purifying a hydrogen gas with a high recovery ratio by removing an impurity constituent from a hydrogen gas extracted by an organic chemical hydride method etc. In the method for purifying a hydrogen gas, a raw material hydrogen gas containing an impurity constituent is purified using two adsorption towers (10A) and (10B) each filled with an adsorbent. The method comprises: repeatedly carrying out an adsorption cycle including at least an adsorption step of separating the impurity constituent from the raw material hydrogen gas by adsorbing the impurity constituent to the adsorbent in the adsorption towers (10A) and (10B), and a heating and regeneration step of desorbing the impurity constituent from the adsorbent by supplying a heated purge gas to the adsorption tower after the adsorption step, in each of the adsorption towers (10A) and (10B); and while carrying out the adsorption step in one adsorption tower, carrying out a step other than the adsorption step in the other adsorption tower. The heating and regeneration step includes circulating the purge gas while heating the purge gas.

Wood pulping process including pulping wood to produce a pulping effluent or liquor. Pre-concentrating the liquor in a pre-concentration unit produces concentrated liquor, a contaminated condensate and a non-contaminated condensate. Directing the concentrated liquor to a multi-effect train of forced circulation solids concentrators that further concentrating the concentrated liquor to form a highly concentrated liquor. Directing the contaminated condensate produced by the pre-concentration unit to a steam stripper and stripping gases therefrom and in the process producing a contaminated vapor stream. Utilizing the contaminated vapor stream and its thermal energy to power the forced circulation solids concentrators of the multi-effect train.

Systems for water treatment include a preprocessing stage, an ultraviolet treatment stage, and a filtering stage. The preprocessing stage includes first and second chambers including first and second filter media. The first and second chambers include perforated plates. The first chamber and second chamber are vertically arranged in a filter tower. The ultraviolet treatment stage receives water in a plurality of reactor tanks. Each reactor tank of the plurality includes an inlet, an outlet, crystal sleeve disposed centrally to the interior of the reactor tank, and a UVC light source contained within the crystal sleeve. A controller operates the ultraviolet treatment stage to sequentially fill each reactor tank and sequentially drain each reactor tank and operates a respective UVC light source to emit UVC wavelength radiation within a respective reactor tank while water is in the respective reactor tank.
