The invention relates to Quench box assembly comprising quench pipe and quench box, to mix quench gas and vapor-liquid effluent from previous catalyst bed to achieve equilibrium temperature before entering the next bed. The quench pipe is in the form of ring having aperture while quench box consists of swirling section and a mixing chamber. The swirling section consists of inclined baffles to provide swirling action to incoming stream and the turbulence created by the swirling action increases the heat transfer rate thus requiring the smaller reactor volume to attain equilibrium temperature. The perforated plate being open from all the sides allowing the liquid to flow uniformly from all directions thus providing uniform distribution on the distributor tray. Hence, eliminates the requirement of rough liquid distributor before the distribution tray.

One aspect of the invention relates to a method comprising a single-stage conversion of an atmospheric pollutant, such as NO, NO.sub.2 and/or SO.sub.x in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO.sub.2.sup.0), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

Integrated exhaust gas systems, methods, and processes are disclosed that includes pretreatment, treatment and post-treatment processes arranged in a variety of reaction environments to address varied application requirements and end product requirements is described in this disclosure. In addition, a contemplated ballast water treatment system—that can be used in combination with the integrated exhaust gas systems can treat seawater and return it to storage within the vessel or send treated water back to the sea. This system can be sized to treat the seawater as it is leaving the ship without prior treatment, while the seawater is aboard or treat the seawater that is within the ship and add any additional treatment to the water, as the seawater leaves the ship. This system is not involved with pumping the seawater into the ship or filtering the water prior to storage as ballast water.

A device for treating crude oil or heavy fuel oil with a method that can lower the pour point to at least 0° C. Crude oil or heavy fuel oil treated thusly maintains this property for at least one year. The device for lowering the pour point of crude oil or heavy fuel oil uses a specific ionization method. The method is conducted by passing a heated medium through the main ionization device which is grounded and which includes three parallelly connected segments whereby each segment includes a protective copper tube inside which a protective insulating shell is situated, inside which a copper housing is situated. In each copper housing there is one cylindrical-shaped external core in which an internal core is placed, and the external core and internal core are manufactured as two different alloys by composition.
