摘要： The invention relates to a tubular reactor with a rotating reactor chamber (9) for thermal treatment of biomass. It is characterized by the reactor chamber (9) being subdivided into zones by ring-shaped plates (10). These zones cause the particles to be retained in a particular area and thoroughly mixed there, i.e., the particles being treated are homogenized and the retention time also becomes more homogenous.

摘要： A method is provided for treating used potassium chloride (KCl) drilling mud for disposal. The process comprises feeding the mud into one end of a rotary tube, advancing the mud through the rotating tube and heating the mud by cascading action using lifters, to expose it to a hot gas stream, thereby partially drying the mud to lumps, further modifying the lumps by contacting them with a burner flame to form clinker pellets, and finally contacting the clinker pellets with a second flame to complete the drying process, producing dried clinker pellets containing the majority of the KCl in the mud, the pellets having a structure that resists the leaching action of water. The pellets further lend themselves to being evenly distributed over fields, so that unwanted excessive concentrations of KCl can be avoided.

摘要： Heavy hydrocarbon containing sludges such as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer to vaporize liquids having a boiling point at atmospheric pressure of less than about 700.degree. C. and to provide substantially dried solid particles discharged from the dryer. The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids, are conducted to a combuster/oxidizer and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like to oxides thereof. A sludge handling system includes a rotary disk type indirect dryer connected to a lift pipe type combustor/oxidizer for thorough exposure of the dried solids to an oxygen containing atmosphere. A centrifigal or cyclone type gas-solids separator receives the flow stream discharged from the lift pipe and a portion of the dried solids may be diverted after discharge from the dryer back to the dryer inlet to reduce the moisture content of the sludge flow stream introduced to the dryer to minimize caking and clogging of the dryer itself.

摘要： An improved paper drying process and machine are described in which the paper web is supported independently of velocity-induced stresses thus permitting operation at speeds significantly in excess of the prior art for each paper grade. The process requires: (1) transporting the web on a supporting fabric that travels from the last press nip through at least the initial portion of a drying section; and (2) holding the web onto its supporting fabric by employing forces normal to the major web surfaces sufficient to overcome those forces which tend to lift the web from its supporting fabric. The web on its supporting fabric travels a serpentine path through the drying section about drying cylinders with the web alternating between direct contact with a drying cylinder followed by indirect contact with the subsequent cylinder. The principal holding forces are preferably pressure differentials created by vacuum boxes arranged to effectively hold the web to its supporting fabric on all portions of the web-fabric combination where the web is not in direct wrapping contact with the drying cylinders. The fabric supports the web at least until the web has attained sufficient strength through increased dryness to resist breaking stresses at the selected machine speed. The products made by the process of this invention possess a unique toughness or stretchability not found in conventionally prepared papers that have been strained or stretched during manufacture. Processes and machine arrangements designed to balance stretchability with certain desirable stiffness properties are disclosed. Pulp furnishes may now be selected for their contribution to product qualities, such as higher finished product tensile strength, rather than principally for wet strength. For example, chemical pulps may be significantly reduced or eliminated from newsprint furnishes where their purpose has been principally to permit economic paper machine speeds. The invention makes attainable speeds approaching twice current operating levels for each paper grade.

摘要： A process for drying and/or calcining bulk material in a rotary kiln when hot gases are passed countercurrent to the flow of bulk material thereto, and the bulk material is dried and/or calcined in the rotary kiln is disclosed. According to the invention, the bulk material is dried and/or calcined, as it passes from the feed end of the rotary kiln to the discharge end thereof, by contacting the same with hot gases and thereafter, as the bulk material passes towards the discharge end of the rotary kiln, the bulk material is heated by indirect heat exchange with such hot gases. An apparatus for carrying out such process is also disclosed. The apparatus is a rotary kiln equipped with a centrally disposed tube, disposed axially within the rotary kiln toward the bulk material discharge end of the rotary kiln whereby an annular space is defined between the outer wall of the central tube and inner wall of the rotary kiln. The apparatus is equipped with means for passing hot gases within the central tube, means for passing bulk material on the outer wall of the central tube whereby the bulk material can be heated by indirect heat exchange with hot gases within the tube.
