摘要： Liquid oxygen, which is extracted from the bottom of a lower pressure rectifier and compressed by a liquid oxygen pump to a predetermined supply pressure, is evaporated in a main heat exchanger to prepare an oxygen gas product, while oxygen gas is circulated in the main heat exchanger at a linear velocity which is equal to or higher than the terminal velocity, calculated depending on the supply pressure, of an oxygen droplet having a diameter of 200 mum. This process effectively prevents precipitation of heavy impurities in the heat exchanger and produces higher pressure oxygen gas at reduced operational costs.

摘要： A tray is disclosed for use in a rectification column through which a liquid stream flows. The tray is of a geometric arrangement including slits formed therein so that w ranges from 1.0 to 3.0 mm, ?/w ranges from 10.0 to 350, T/w ranges from 1.3 to 5.0, and p/w is at least 1.3, where w represents the width of the slits, ? is the length of the slits, T represents the spacing between adjoining slits in a direction of liquid stream flow, and p represents the spacing between adjoining slits in a direction at a right angle to the direction of liquid stream flow. The values of w, ?/w, and p/w are chosen to provide maximum tray efficiency with minimum pressure drop across the tray at high liquid stream velocities. The tray disclosed allows operation of the rectification column at high gas velocities thereby increasing capacity and reducing column size requirements.

摘要： Water (2) containing organic substances is modified by impressing an electric field having an alternating current pulse voltage to oppositely arranged electrodes (maintained in a non-contact state with water) configured adjacent to the outer wall of the discharge container (1), and inducing discharge during potential inversion. An Independent claim is also included for a discharge device comprising a discharge container filled with water and covered with a high dielectric and insulating member (C), two or more electrodes (3), an electric power unit (4) and an aerator (5).

摘要： Gaseous oxygen is produced first making liquid oxygen by liquefying and rectifying untreated air, then compressing the liquid oxygen to a preset pressure and evaporating it by introducing it at that pressure into a heat exchanger. The oxygen gas flows upwards at a linear velocity at least equal to the terminal velocity (u) of a droplet of liquid oxygen having a diameter of 200 micro m where u = ((4g ( rho L - pi G)2 Dp )\/(225 mu rho G))1/3 g is gravity; pi L and pi G are the density of saturated liquid and saturated gaseous oxygen at the preset pressure; rho is viscosity of the saturated oxygen gas at the preset pressure and DP is droplet diameter. Preferably the linear velocity is at least equal to the terminal velocity of a droplet of 500 micro m or more preferably 1mm where u = ((3.03g ( rho L - pi G) Dp )\/( rho G))2.

摘要： PROBLEM TO BE SOLVED: To exhibit excellent deodorizing effect even when concn. of odor ingredients is remarkably changed by providing at least two stages of treating towers filled with microorganisms and/or an adsorption material and providing a treating tower filled with a porous body exhibiting oxidative decomposition performance to the odor ingredients between arbitrary treating towers. SOLUTION: When odors of waste water treatment contg. an odor ingredient (A) contg. hydrogen sulfide, etc., being easily decomposable under oxidative atmosphere and an odor ingredient (B) contg. other ingredients such as dimethyl sulfide are removed in an deodorizing apparatus, an deodorizing apparatus wherein at least two stages of treating towers filled with microorganisms and/or an adsorption material is utilized. Then, at first, the odor ingredient (A) is removed under oxidative atmosphere in a treating tower filled with a microorganism acting specifically to this. Thereafter, after remaining odor ingredient (A) which has not been removed in the treating tower is removed in a treating tower in which a porous body exhibiting oxidative decomposition catalyst performance to this is filled, other odor ingredients (B) are removed in a treating tower filled with a microorganism acting specifically to them.
