Abstract: The present invention discloses a extra thick hot rolled H section steel and a production method therefor. The extra thick hot rolled H section steel contains, by mass, the following chemical components: 0.04-0.11% of C, 0.10-0.40% of Si, 0.40-1.00% of Mn, 0.40-1.00% of Cr, 0.10-0.40% of Cu, 0.020-0.060% of Nb, 0.040-0.100% of V, 0.010-0.025% of Ti, 0.010-0.030% of Al, 0.0060-0.0120% of N, not more than 0.015% of P, not more than 0.005% of S, not more than 0.0060% of O, and the balance Fe and trace residual elements, wherein 0.090%?Nb+V+Ti?0.170%, 6.5?(V+Ti)/N?10.5, and 0.30%?CEV?0.48%. The extra thick hot rolled H section steel has a flange thickness of 90 mm-150 mm, has excellent comprehensive mechanical properties, and can well meet the needs for heavy supporting structural parts of high-rise buildings, large squares, bridge structures, etc.

Abstract: Provided is an apparatus for removing impurities from feed water comprising (A) a loading tank comprising a top, a bottom, and an interior, and further comprising (i) an inlet that conveys the feed water to a water distributor, (ii) a grid located above the water distributor, (iii) an outlet located at a level higher than the grid, (iv) an outlet at the bottom of the loading tank, (B) a regeneration tank comprising (i) a first inlet near the top of the regeneration tank, (ii) a second inlet at the top of the regeneration tank, (iii) an outlet at the bottom of the regeneration tank, (C) a pipe that conveys material from the bottom of the regeneration tank to the top of the loading tank, wherein said regeneration tank is located below the loading tank. Also provided is a method of removing impurities by using such an apparatus.

Abstract: A method for treating an oil-containing aqueous mixture comprising the step of passing the mixture (1) through a media (6) comprising a bead-form cation exchange resin combined with a cationic surfactant, wherein the resin includes a sulfonated crosslinked copolymer matrix having a rough surface characterized by having a frequency of at least 5 peaks and valleys per sample surface area (283 um×212 um), where the difference between the average height of the 5 highest peaks and the 5 lowest valleys is at least 6 ?m.

Abstract: Encryption logic to identify a particular session key, where the particular session key is one of a plurality of session keys for use in encrypting content to be sent from a first device. The encryption logic is to encrypt particular content with the particular session key to obtain encrypted particular content. I/O logic is provided that can cause the particular content to be sent with a key refresh structure, where the key refresh structure is to identify that the particular session key was used to encrypt the particular content.

Abstract: A method for treating an oil-containing aqueous mixture comprising the step of passing the mixture (1) through a media (6) comprising a low bead-form cation exchange resin combined with a cationic surfactant, wherein the resin includes a sulfonated crosslinked copolymer matrix having a rough surface characterized by having a frequency of at least 5 peaks and valleys per sample surface area (283 ?m×212 ?m), where the difference between the average height of the 5 highest peaks and the 5 lowest valleys is at least 6 ?m.

Abstract: A process for treating coking wastewater contains the steps of passing the coking wastewater in such an order through coagulation, particles removal, and ion-exchange resin.
