The invention relates to improvements of a heat exchanger, particularly a scraping heat exchanger having an outer cylinder comprising a first wall having a smooth circle-cylindrical inner side, and an inner cylinder positioned concentrically within it. The improvements regard a simple detachable inner cylinder, a heat exchanger with lid including a fluid barrier, a heat exchanger with a tangential output, and a method and heat exchanger adapted for improved evacuation of a product chamber of a heat exchanger.

A device and process for the vacuum pyrolization of scrap tires to produce a pyrolytic oil from which valuable terpenes such as limonene and pulegone may be extracted and purified.

A phenylene ether oligomer composition is disclosed comprising, a phenylene ether oligomer having an external amine content of less than or equal to 1.5 weight percent; and a residual solvent in an amount of 10 to 10000 parts per million by weight, based on the weight of the phenylene ether oligomer composition; wherein the phenylene ether oligomer composition has an intrinsic viscosity of 0.03 to 0.13 deciliter per gram; a glass transition temperature of 135 to 175 C., or a combination thereof.

A multi-functional slurry processing system (VARCOR) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.

A system and process for decontaminating a bio-contaminated wastewater fluid as from a slaughterhouse or similar facility. The system and process recovers purified vapor/steam through a decontamination unit having a plurality of alternating rotating trays and fixed baffles in a processing vessel producing separate purified and contaminant streams. One or more filter/strainer units are disposed in parallel before the decontamination unit, and may be used alternately while the other is cleaned. A rotating shaft connected to the rotating trays may also connected to an electrical generator to provide electricity for circuits and controls in the system.

A distiller including an evaporator having at least one evaporation surface for evaporating liquid into vapor. At least one movable liquid applicator assembly has a wiper applicator which can move over the at least one evaporation surface, for wiping and applying a thin even film of the liquid on the at least one evaporation surface for evaporation.

The invention relates an evaporator. The evaporator may include a drum. The drum may have a first portion and a second portion. The drum may include a product inlet positioned at the first portion of the drum, a product outlet positioned at the second portion of the drum, a vapor outlet, and an agitator. The evaporator may have a heating jacket and/or a product supply pipe. The heating jacket may be configured to surround the drum and/or to heat the product in the drum. The product supply pipe may be positioned outside the drum and/or may extend from the second portion of the drum to the product inlet positioned at the first portion of the drum. The product supply pipe may be in direct contact with the heating jacket.

A process for producing a fluorinated copolymer includes polymerizing a fluorinated monomer having a carboxylic acid functional group or a sulfonic acid functional group and a fluorinated olefin by a solution polymerization method in a polymerization medium to obtain a mixture containing a fluorinated copolymer, an unreacted monomer and the polymerization medium. The mixture is continuously or intermittently transferred to an evaporation vessel provided with a stirrer and heating the mixture with stirring in the evaporation vessel to evaporate and recover the unreacted monomer and the polymerization medium.

A steam stripping apparatus is provided that prevents adherence of crumbs to an inner wall of a crumbing tank, pipe blockages caused by reaggregated large particle size crumbs, clogging of a screen by small particle size crumbs, and slipping in an extruder, and which can operate over a long period of time. The crumbing tank includes a stir shaft and an impeller, and also has a baffle plate on an inner wall face. The impeller has a knife blade. The baffle plate has an approximately triangular cross-sectional shape having, on a cross section in a cylindrical lateral direction of the crumbing tank, a side face on each of an upstream side and a downstream side with respect to a flow direction of a fluid, and in which the upstream-side side face and the downstream-side side face meet to form an intersection point.
