摘要： This drying method is for drying an article to be dried (W3) that contains moisture, in a drying device (1) which includes at least a fluidizing chamber (12) and a mixing chamber (14). In the method, a pre-dried article (W1) obtained by pre-drying an article to be dried (W3) is supplied to the inside of the fluidizing chamber (12), and in that state, the article is fluidized into a fluidized pre-dried article (W2), and this fluidized pre-dried article (W2) is moved to the inside of the mixing chamber (14), which is separated from the fluidizing chamber (12) by a partition (13) and which communicates with the fluidizing chamber via a through-hole (13a) formed in the bottom of the partition (13). In this state, an article to be dried (W3) is fed from above the through-hole (13a) to be mixed with the fluidized pre-dried article (W2).

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling the quality of a finished product hydrogen gas by a PSA process by which it is possible to obtain the hydrogen gas of a stable finished product quality without the necessity to use analyzing instruments. SOLUTION: This method for controlling the quality of a finished product hydrogen gas by a PSA process uses an analyzing instrument 11 which measures the density of a component gas most hardly adsorbable among impurity gases or the density of one of gases selected as hardly adsorbable components, arranged on the outlet side of adsorption columns A-C. In addition, a flow rate regulating valve 12 is installed on the outlet side of the adsorption columns A-C and is controlled so that the peak value of the density of the gas measured by the analyzing instrument 11 is a constant value or stays within a constant range.

摘要： PURPOSE: To produce high-purity carbon monoxide and hydrogen from a gaseous mixture without need for a large power at the time of forcing a gas necessary to purge an adsorption tower into the tower under pressure. CONSTITUTION: A gaseous mixture contg. carbon monoxide and hydrogen is introduced into an adsorption tower while maintaining a working pressure selected to control the partial pressure of carbon 2 monoxide to 1-5kg/cm A in the adsorption stage. The gas in the adsorption tower is discharged under atmospheric pressure after the adsorption stage, and the pressure in the tower is lowered close to atmospheric pressure in the discharge stage. The adsorption tower is further evacuated by a vacuum pump to desorb the carbon monoxide adsorbed on an adsorbent in the desorption stage. The hydrogen obtained in the adsorption stage is forced into the adsorption tower under pressure after the desorption stage to increase the pressure in the tower above the pressure necessary to the succeeding adsorption stage in the pressure increasing stage.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for discharging slag produced in a method for producing a fuel gas by gasifying a waste plastic. SOLUTION: The aggregation of the waste plastic on a water surface of a cooling water tank by which discharge of melted slag from the waste plastic is hindered is prevented by the following methods. (1) Spraying water in an upper space on water surface, (2) vibrating the water surface by blowing gas from the lower part of the water tank, (3) vibrating the water surface by opening a slag discharge lock hopper in a state unfilled with water and (4) preventing aggregation of unreacted plastic particles and promoting smooth discharge by preparing water current from the central part of the water tank into the direction of a wall surface.

摘要： PROBLEM TO BE SOLVED: To efficiently operate a PSA process, to enhance the throughput and recovery rate while restraining a raise in cost and to conduit efficient and safe operation. SOLUTION: When an inflammable component comprising hydrocarbons and/or H2 is recovered from a gaseous starting material mainly comprising the inflammable component and a noninflammable component comprising CO2 and/or N2, at least three adsorption towers and an adsorbent having pore size between molecular diameters of the inflammable component and the noninflammable component are used so that a cycle comprising an adsorption step, a pressure-reducing step, a desorption step and a pressurizing step is carried out at each adsorption tower while postponing the cycle time. It is preferable that the exhaust gas at the pressure-reducing step is supplied to the adsorption step as a recycle gas together with the gaseous starting material and that the desorption step is carried out after carrying out a washing step using the gas exhausted at the desorption step as a washing gas after the pressure-reducing step is ended. It is also preferable that a pressure-equalizing step is carried out by connecting the tower where the adsorption step is ended to the tower where the desorption step is ended. According to this method, a high calorie town gas can be steadily supplied from a coke furnace gas, etc.
