    Abstract: An apparatus and method for recovering constituents and/or heat energy from a fluidized bed combustion process utilizes a single vessel which combines a combustor for fluidized bed combustion of a chemical mixture fed therein and a heat exchange section. Characteristics of the fluidized bed are controlled by withdrawing an appropriate portion of the larger, unburned constituent particles from the bottom of the combustor, and smaller constituent particles are withdrawn by becoming entrained within the gases of combustion and being transported to the heat exchange section. The smaller particles are separated from the gases without the use of a cyclone separator and accumulate as another fluidized bed in the heat exchange section where heat is adsorbed from the particles for recovery purposes and to cool the particles. A portion of the cooled particles is then recirculated to the combustor by, for example, pneumatic transport methods for controlling the operating temperature of the combustion process. The apparatus is particularly well-suited for recovering process salts and heat energy from the burning of black liquor effluent from a lignocellulosic pulping process.

    Abstract: This invention constitutes an improved method for condensing fatty acids, particularly from steam streams exiting from distillation columns. Steam streams containing entrained high-titre fatty acids can be condensed in surface condensers if certain conditions are maintained. A surface condenser, having a shell and tube configuration, is oriented in a vertical position rather than the horizontal position often employed. Quite contrary to normal processing, the cooling medium is passed through the shell side of the surface condenser and the steam stream containing entrained high-titre fatty acids is passed through the tube side. Conditions must be maintained within the tube side of the condenser so that a velocity of at least 30' per second is provided and the steam stream must contain at least about 70% steam, by weight, in the tube side of the surface condenser.

    Abstract: A process and system are provided for economic utilization of solar energy. Solar energy is absorbed and converted to thermal energy by means of at least two systems, operating in different temperature ranges, for circulating a primary fluid heat transfer medium through separate collector sections of a solar receiver to recover solar heat and through separate output heat exchangers to supply heat to a second heat transfer medium functioning as a working medium, with heat storage means being associated with each system for the purpose of satisfying the heat requirements of the working fluid and also to prevent cooling down of the collector during the time that little or no solar radiation is available.

    Abstract: Cooling the highly viscous reaction mass during catalytic polymerization of liquid olefins to polyolefins by pumping it to and from the reactor through the tubes of a heat transfer single pass cooler rather than a heat transfer multi-pass cooler as has been done in the past, increasing the number of the tubes in the single pass cooler as compared to the multi-pass cooler, reducing the diameter of the tubes and increasing the pump capacity. The number of tubes and pump capacity are increased sufficiently and the internal diameters of the tubes are decreased sufficiently so that the heat transfer coefficient of the single pass cooler is between 10 and 20 BTU/ft.sup.2 hr. .degree.
