The system and method spatially predict the condensation of water and acid from the flue gas in the condensing heat exchanger installed in fossil power plant flue gas treatment system or similar environment. By modifying the operational conditions, the heat exchanger can control rates and areas of condensations. The system and method adjust either the cooling water temperature or the flowrate ratio of flue gas to cooling water to control the condensation rates of water or acids. The system and method also estimate actual coverage areas to apply for anti-corrosive coating onto the tube or duct surfaces to resist corrosion due to acid condensation. The system and method also optimize or customize condensation rates of water and acids in boiler flue gas under operating conditions given at a power plant.

The present invention relates to an improved water pipe comprising a chamber containing water in its lower portion, its upper compact cylindrical portion serving as a smoke collection reservoir; a bowl for combusting tobacco or medicinal herbs, the smoke directed through a tube to the water chamber below the water; and a mouth piece for applying suction to the interior of the chamber to inhale the smoke.

A cabin air filtration system and method for regenerating a cabin air filtration system are disclosed. The filtration system includes a frame, and a renewable sorption layer within the frame, the renewable sorption layer configured to clean air from one or more of outside of an automobile and inside an automobile. The cabin air filtration system for an automobile can include a first layer, the first layer configured to particulates, and a second layer, the second layer configured to remove volatile compounds and gases. The method includes placing a renewable sorption layer within a frame in an oven, the renewable sorption layer configured to filter air from one or more of outside of the automobile and inside the automobile; creating a vacuum within the oven; and heating a source of water within the oven to perform a steam regeneration treatment on the renewable sorption layer.

An upper end cap including an inner filter member that surrounds a middle space portion, an outer filter member that surrounds the inner filter member, and an introduction port for introducing compressed air into the middle space portion, and a lower end cap that closes a lower end portion of the middle space portion, an outer periphery of a lower end portion of the inner filter member being surrounded by an inner wall, an outer periphery of a lower end portion of the outer filter member being surrounded by an outer wall, an upper end surface of the outer wall being positioned higher than an upper end surface of the inner wall, a liquid discharge passage being formed between the outer wall and the inner wall, the liquid discharge passage being in communication with a liquid discharge hole that open to an underside of the lower end cap.

A method of cleaning naturally occurring radioactive materials (NORMs) from filtration socks utilizes a system that is equipped with a centrifuge, a disposal well, a surfactant and heated water. Through oil production, filtration socks become saturated with oil and NORMs. Typically, the used filtration socks are disposed of in a radioactive landfill or other proper disposal means. Through the method of cleaning NORMs, the used filtration socks are placed into a washing drum within a centrifuge and agitated with a surfactant and heated water to extract the NORMs from the used filtration socks. The centrifuge is spun to eject the waste solution from the washing drum, where the waste solution is pumped out of the centrifuge and into a class II disposal well to properly dispose the NORMs and brine from oil production processes. Cleaned filtration socks are then reusable or disposable in a more convenient manner.
