Title: Preconcentration of sp spent acid with non-purified calcination waste gases in a venturi scrubber
Inventor: BOEHM ERNST
IPC: C22B34/12
Filed: 1991-09-05
Abstract: ABSTRACT The invention relates to a process for the preconcentration of the waste acid obtained in the production of titanium dioxide by the sulphate process and to the use of a device for this process. It utilizes the heat of the hot unpurified calciner exhaust gases obtained in the calcining of titanium dioxide hydrate, waste acid being fed into an acid circuit, the recirculating acid being directly contacted in a venturi scrubber with the calciner exhaust gases, and part of the recirculating acid being withdrawn from the acid circuit.. in the form of preconcentrated acid. Part of the recirculating acid is rapidly mixed with the calciner exhaust gases at the upper end of the venturi scrubber, a second portion is applied, at the same level, via a weir, onto the interior wall of the venturi scrubber and, in the venturi neck, mixed with .the calciner exhaust gases. Below the venturi scrubber, the calciner exhaust gas is separated from the acid. The acid is preconcentrated from between 20 and 24% H2SO4 to between 25 and 28% H2SO4 and the calciner exhaust gas is cooled preferably from between 250 and 400°C to between 85 and 100°C.

Filed: 1990-05-09
Abstract: The invention relates to a method of removing solid salt by-product from a gaseous hypohalogenated acid product stream in a reactor that reacts an aqueous alkali metal hydroxide and a gaseous halogen. The method of the invention comprises the steps of (a) feeding a gaseous product dust-laden with by-product salt into a separation means; (b) collecting solid salt by-product on the exterior of a plurality of suspended bags; (c) pulsing a dry gas consisting essentially of halogen through the plurality of suspended bags to inflate the bags and cause the solid salt by-product to fall from the exterior of the suspended bags into a collection location within the separation means, the halogen gas and gaseous product being fed into a recirculation loop connected to the reactor; and (d) removing the separated solid salt by-product from the separation means. The invention permits extremely small-sized salt particles to be removed in the 0.5 to 50 micron size range.

Title: Two step process for sweetening a sour hydrocarbon fraction
Inventor: FRAME ROBERT R
IPC: C10G45/06
Filed: 1991-11-18
Abstract: This invention relates to a two step process for sweetening a sour hydrocarbon fraction containing tertiary mercaptans and primary or secondary mercaptans. In one step the mercaptans in the sour hydrocarbon fraction are reacted with hydrogen in the liquid phase and in the presence of a selective hydrogenolysis catalyst to selectively hydrogenolyse the tertiary mercaptans. Inanother step, the primary and/or secondary mercaptans are oxidized by reacting them with an oxidizing agent in the presence of oxidation catalyst and a basic component. The selective hydrogenolysis step and the oxidation step may be carried out in any order, i.e., either hydrogenolysis first followed by oxidation or vice versa.

Abstract: Nitrate-polluted run-off water from a field is conveyed via land drains to a reservoir. The reservoir is large enough to contain excess quantities of storm water from the field. From the reservoir, the run-off water enters a tank which contains wood or other organic carbon material. The wood is kept under water, ie under anaerobic conditions, whereby the nitrate is broken down by bio-chemical action. Sufficient wood is provided, and the flow rate is so adjusted, that the nitrate-polluted water spends many hours in contact with the wood.

Abstract: Apparatus and method for making powder from a metallic melt by atomizing the melt to form droplets and reacting the droplets downstream of the atomizing location with a reactive gas. The droplets are reacted with the gas at a temperature where a solidifed exterior surface is formed thereon and where a protective refractory barrier layer (reaction layer) is formed whose penetration into the droplets is limited by the presence of the solidified surface so as to avoid selective reduction of key reactive alloyants needed to achieve desired powder end use properties. The barrier layer protects the reactive powder particles from environmental constituents such as air and water in the liquid or vapor form during subsequent fabrication of the powder to end-use shapes and during use in the intended service environment.

Abstract: ABSTRACT OF THE DISCLOSURE A high dynamic strength or fatigue resistance is achieved in a taper thread reinforcing bar splice for use in steel reinforced concrete by coordinating the elongations of the coupler sleeve (10) and bar (12, 14) to achieve the required movements of the coupler sleeve at the mouth. This is accomplished in the preferred embodiment by two attenuation grooves on the outside of a circular cylindrical coupler body at each end, each groove ( 28, 29, 35, 36) being placed in a particular axial relationship with respect to the end of the coupler sleeve and the area of thread engagement with the bar The grooves are of different depths, with the groove (35, 36) closest to the mouth of the coupler sleeve being the deepest. Also the diameter of the circular cylindrical coupler body at each end is selected so that the wall thickness at the mouth is as thin as possible. At the center of the coupler sleeve there is an enlarged portion (24) extending axially several threads beyond the last thread of each bar joined. The enlarged portion may be circular or hexagonal in exterior configuration. A lead chamfer (26, 27) which forms the innermost side wall of the attenuation grooves (28, 29) closest to the center of the coupler sleeve is desired to avoid excessive stress concentration at the side of these grooves. For such improved fatigue or dynamic performance of the splice, and efficient static performance, it is preferred to employ rolled bar thread in the splice system.
