Abstract: A pressure-tight vessel subjected to severe thermal cycling through a temperature range including temperatures up to in excess of approximately 700° F. Unlike conventional pressure-tight vessels that are constructed of plates arranged horizontally, the vessel is built of plates that are greater than sixteen feet high. As a result, there are no circumferential seams in a critical area of the cylindrical section of the vessel, providing superior durability.

Abstract: The speed of coal gas desulfurization is improved and the total size of the apparatus can be made compact. The apparatus comprises a sulfide-ion-producing portion (54), which reacts with a sulfur compound being supplied by the coal gas and produces sulfide ion S2− in molten carbonate. A sulfur compound discharge portion (53) discharges a sulfur compound produced by a reaction with sulfur discharge gas (56).

Abstract: An improved reactor for generating water from hydrogen and oxygen which allows production of moisture at a high conversion rate exceeding 99 percent with the temperature kept under some 400° C. inside the reactor shell (1) and with the water vapor production being more than 1,000 sccm. One form of the reactor (FIG. 1) according to the invention is constructed with a closed cylinder divided into two compartments by an interior partition, a first reactor structural component (2) and a second reactor structural component (3), united to define a sealed interior space (1a). The sealed interior space (1a) of the reactor shell (1) is partitioned by a diffusion filter (10) into a first chamber (1b) provided with an inlet reflector unit (9) and a second chamber (1c) provided with an outlet reflector-diffuser unit (11). On the inside surface of the second reactor structural component (1c) is formed a platinum coated catalyst layer (13).

Abstract: Disclosed is an apparatus for supplying hydrogen chloride gas from a hydrogen chloride gas generator to an absorbing reactor through a gas supply pipe, and a method for producing hydrochloric acid by allowing the gas absorbed in water in an absorbing reactor. The apparatus obtains a large amount of high purity hydrochloric acid having extremely low impurity concentration with a simple system. The inner wall of the gas supply pipe is constructed with such materials from which impurities are not eluted by hydrochloric acid at least to the position of the wall which is reached by the backward flow or splash of produced hydrochloric acid, vapor of the hydrochloric acid or water in an absorbing reactor.

Abstract: An apparatus and a process for cooling a feed injector of a gasification reactor that produces synthesis gas is described. Cooling fluid is injected into a channel in the feed injector adapted for circulating the fluid. The injection pressure is maintained near or above the gasification reactor pressure. The fluid is withdrawn from the channel through an outlet at an outlet pressure between about 515 KPa above to about 1030 KPa below the gasification reactor pressure. The fluid is cooled, degassed, and injected back into the channel in the feed injector. The pressure on the cooling system is variable and tracks the gasification reactor pressure.

Abstract: A method for the concentration of liquid mixtures, comprising the step of causing a continuous stream of the liquid mixtures to flow in the form of a turbulent thin layer in contact with a heated wall; for that purpose, a continuous stream of liquid mixture is fed into a turbo-concentrator comprising a cylindrical tubular body (1), a heating jacket (4) and a bladed rotor (8) rotatably supported in the cylindrical tubular body (1), and is centrifuged to form a dynamic and tubular thin layer, the thin layer advancing inside the cylindrical tubular body (1) then being discharged continuously in the form of a stream of concentrated liquid mixture.

Abstract: A distillator has an outer casing, a boiling device disposed in the outer casing, a hot water box disposed in the outer casing, a cold water box disposed in the outer casing, a first faucet disposed on the hot water box, a second faucet disposed on the cold water box, a first vapor pipe connected to the boiling device and the hot water box, a second vapor pipe connected to the hot water box and the cold water box, a water pipe connected to the boiling device and the cold water box and passing through the hot water box, the water pipe inserted in the first vapor pipe and the second vapor pipe, a heating device disposed on the boiling device, and a heater disposed on the hot water box. A connection is disposed on an end of the water pipe and passes through the cold water box.

Abstract: The present invention pertains to a synthesis gas heat exchanger unit with one synthesis gas radiant cooler (1), two synthesis gas convection coolers (23), one crude gas-clean gas heat exchanger (4), one crude gas-inert gas heat exchanger (5), and one dust separator (11). These devices are preferably arranged vertically or slopingly. The crude gas heat exchangers (4, 5, 23) are designed as single-flue, double-flue or multiple-flue heat exchangers. They are elastically supported via claws (10) and are equipped with an electric heater (9). A soot blower system (13) is associated with each flue (4.1, 4.2) as well as (5.1, 5.2) and right hand flue and left hand flue (23.1, 23.2) at the crude gas inlet. Soot blowers (31) are likewise provided on the connection lines (2, 6), and mass flow controllers (7) are provided in the lower connection lines (6).
