  • Patent number: 8945286
    Abstract: The invention relates to a device and method for treating a hot gas flow containing slag and to an entrained-bed gasifier system that comprises the device. The device comprises, in a housing, an inlet arranged at the top for the hot gas flow, an immersion pipe, which is arranged vertically and concentrically in the housing and into which the inlet opens, a coolant bath, into which a lower section of the immersion pipe is immersed, and at least one raw gas outlet opening for cooled raw gas that has been freed of slag. The lower section of the immersion pipe is designed as a radially expanded gas distributor bell in the coolant bath. Said gas distributor bell is formed by a substantially conical jacket surface having a cross-section that expands downward, wherein the jacket surface has a plurality of gas passage openings, which are distributed over the circumference of the gas distributor bell. The dimensions of the gas passage openings increase with the immersion depth in the coolant bath.

  • Publication number: 20120108681
    Abstract: The present invention is a multiple reaction set for the production of chemicals by equilibrium limited reactions utilizing plate-type or extended surface heat exchangers. The heat exchangers cool the reaction products to condense methanol within the reaction products for separation, and to warm incoming feed reactants prior to entrance of the reactants into a reactor utilized for methanol production. The various reactors, heat exchangers, and separators can be formed as separated zones within enclosed vessels, thereby eliminating the need for separately constructed reactors, heat exchangers, and separators. Multi-stream plate-type of extended surface heat exchangers can be utilized to allow efficient cooling and methanol separation.
