An assembly for treating gaseous emissions has a substrate with cells for the passage of an emissions gas to be treated and inductive heating elements located in some of the cells. An electromagnetic field generator mounted near the substrate generates a varying electromagnetic field, so as to inductively heat the inductive heating elements and so heat the substrate. Some of the inductive heating elements have a first natural resonant frequency other inductive elements have a second natural resonant frequency different from the first resonant frequency. A power supply for the electromagnetic field generator is operated with a frequency closer to the first resonant frequency for a time and is operated with a frequency closer to the second resonant frequency period for a subsequent time period. By switching between the frequencies at different times, the heating profile can be moved in the substrate.

The invention solves the problem of separation of a mixture of gases with varied molecular weights. According to the invention, the separation of a gas mixture consists in that a mixture of gases with varied molecular weights in fed into the inside of the device through slots in the inlet conduit, said slots disposed near capillary tubes having negative potential, whereas the outlet channels for the heavier molecular weight gases and those for the lower molecular weight gases are separated with a shutter with holes, said shutter being cyclically closed and opened for a period of time from 0.02 to 1.5 second. A centrifuge for the separation of gases has a cylindrical chamber, a capillary-and-blade electrode with negative potential located in the axis of the chamber and embedded on a conduit that feeds the gas mixture to the separator, an annular electrode being on the positive potential of the power source and grounded, located on the centrifuge perimeter, and is provided with two magnets, permanent or electromagnets. The electrode has capillary tubes connected to tubes and to the negative terminal of the power source. At the outlet of the electrode with the heavier gas holes is a first sliding shutter with holes and at the inlet of the light gas discharge pipeline is a baffle with holes and a second sliding shutter with holes, the first and the second shutter and being connected via a sliding mechanism to a controller.

The present disclosure relates to a system and method for treating wastewater, the method comprising the steps of: providing a vessel for receiving wastewater and a gas, wherein the gas comprises one or more constituent gas components; directing the wastewater and a first gas component of the gas to the vessel; reducing the temperature of the contents of the vessel from a first temperature to a second temperature to facilitate the formation of clathrate hydrates comprising the wastewater and the first gas component; increasing the temperature of the contents of the vessel with respect to the second temperature to facilitate melting of the clathrate hydrates; and removing clean water and/or the first gas component from the vessel.
