Abstract: A green treatment process for cleaning exhaust gas generated in the air oxidation of benzene homologs is disclosed. It takes the hot pressurized exhaust gas generated in the benzene homolog air oxidation process as driving power and heating source: firstly, introducing the said exhaust gas into a turbine refrigerator so that it can drive the refrigerator to generate the cooling capacity that will be utilized for condensing the gas phase in the upper part of the flash evaporator and for trapping organics entrained in the exhaust gas; then, leading the exhaust gas with lowered temperature and pressure into corresponding heat exchangers to provide a part of heating source for the flash evaporator and to preheat the reaction raw materials. Furthermore, introducing the condensed exhaust gas into a water absorption scrubber for further removal of trace organics entrained therein.

Abstract: A multiphase catalytic tower-shaped impinging-stream reactor in the form of a tower, the upper part of which is a plate or packed tower 4 and the lower part of which is a multiphase catalytic impinging-stream reaction kettle 2; the upper part and the lower part are separated by a flow channel plate 14 which has a plurality of round holes serving as flow channels 62; at the top of the reaction kettle 2 exists an upper ejector 3 and at the bottom of the reaction kettle 2 exists a lower ejector 8; near to the side wall of the reaction kettle 2 stands a baffle plate 5, which separates a static liquid zone within the reaction kettle 2 is disclosed.

Abstract: A floating valve providing a parent-and-subsidiary flow-guided floating valve of low pressure drop, high throughput and highly flexible operation maintaining high efficiency within a wide range of gaseous load changes is disclosed. Furthermore, a parent-and-subsidiary flow-guided floating valve having at least two legs, wherein the body of the parent valve is a symmetrical plane figure with the central axis line as the symmetrical line, the central axis line to the overflow cofferdam along the direction in which the liquid flows is also provided.

Abstract: A catalytic reaction-rectification integrated process and a catalytic reaction-rectification integrated column (T-01), the specialized device of such process. The process comprises that the reactants are preheated and mixed with catalysts, and then fed into a jet agitation reaction section (6) located in the middle of the catalytic reaction-rectification integrated column (T-01) from a feeding inlet. The jet agitation reaction section (6) is a kettle-like reactor located in the middle of the catalytic reaction-rectification integrated column (T-01). After pressurized by a centrifugal pump (21), the reactant materials are admitted into a subsonic or transonic agitator (33) located within the reaction section (6). The reactant materials are ejected into the jet agitation reaction section (6) at high speed, to efficiently mix the solid and liquid phases in the reaction section (6) and to reinforce heat and mass transfer efficiency during the reaction.

Abstract: This invention relates to the core component of a floating valve tray-floating valve. The objective is to provide a parent-and-subsidiary flow-guided floating valve of low pressure drop, high throughput and highly flexible operation that can maintain high efficiency within a wide range of gaseous load changes. The technical proposal is: a parent-and-subsidiary flow-guided floating valve, wherein the body of the parent valve is a symmetrical plane figure with the central axis line as the symmetrical line, the central axis line points to the overflow cofferdam along the direction in which the liquid flows and there are at least 2 legs below the body of the parent valve. The front leg is longer than the rear leg so that when the parent valve is fully open, a 2-10 degree angle opens between the body of the parent valve and the valve orifice toward the overflow cofferdam.
