An ionic oxidation refreshing system for refreshing an odorized item, comprising an enclosure with an airflow system to contact the odorized item on all sides; an ionization system that produces a positively charged ionized ozone gas mixture inside of the enclosure, killing germs, including odor-causing bacteria, viruses, molds, and fungus, and provides the odorized item inside the enclosure with a net positive charge; a filter that neutralizes and filters out any toxic by-products; an electrostatic liquid atomization system that creates a fine mist of a quick-cleaning solution, and, in conjunction with the airflow system, causes solution droplets to penetrate deep into the odorized item and agitate a surface of the odorized item, ensuring the formula is evenly delivered onto the odorized item without over saturating any area.

A method of natural gas treatment including introducing a natural gas containing stream into a dryer unit, thereby producing a treated natural gas containing stream. Introducing the treated natural gas containing stream into a nitrogen rejection unit, thereby producing a further treated natural gas stream as a nitrogen rejection unit product. Splitting the nitrogen rejection unit product into at least two portions, introducing the first portion of the further treated natural gas stream into a reformer unit as first part of feed, and introducing a second portion of the further treated natural gas stream into the dryer unit as a regeneration stream, thereby producing a regeneration waste stream. Introducing at least a portion of the regeneration waste stream into the reformer unit as second part of feed.

The present disclosure relates to a purge system for a vapor compression system, where the purge system includes an emission canister configured to receive a gas flow. The gas flow includes a mixture of non-condensable gases and refrigerant of the vapor compression system. An adsorbent material is disposed within the emission canister and configured to adsorb the refrigerant and enable the non-condensable gases to flow toward an exhaust of the emission canister, where the adsorbent material is a silica gel.

An exhaust dust removal system includes an electric field device (1021) and a cooling device. The electric field device (1021) has an electric field device inlet, an electric field device outlet, a dust removal electric field cathode (10212), and a dust removal electric field anode (10211). The dust removal electric field cathode (10212) and the dust removal electric field anode (10211) are used to generate an ionizing dust removal electric field. The cooling device is used to reduce the exhaust temperature before the electric field device inlet. The exhaust dust removal system may help reduce greenhouse gas emissions, and may also help reduce emissions of harmful gases and pollutants, which thereby makes the gas emissions more environmentally friendly.

This invention belongs to the technical field of green preparation of environmentally friendly catalysts, and discloses a preparation method and application of mesoporous FeCu—ZSM-5 molecular sieve, in particular to a method for synthesizing mesoporous FeCu—ZSM-5 molecular sieve by one-pot method and the application in selective catalytic reduction (SCR) denitration reaction. This invention firstly proposes to combine the two calcinations after demolding and ion exchange into one, that is, the original powder is directly calcined to prepare a FeCu—ZSM-5 molecular sieve. The molecular sieve has several advantages such as window with wide temperature window, low cost, good hydrothermal stability and high SCR denitrification activity. Besides, the synthesis process does not use a (large) pore template, nor does it use a post-treatment method to construct the mesopores. Therefore, the method of the invention not only has the advantages of simple process, simple operation, but also good economic and environmental benefits.

An exhaust gas dust removal system, comprising a dust removal system inlet, a dust removal system outlet and an electric field apparatus, the electric field apparatus comprising an electric field apparatus inlet, an electric field apparatus outlet, a dust removal electric field cathode and a dust removal electric field anode, the dust removal electric field cathode and the dust removal electric field anode being used for producing an ionising dust removal electric field. A dust collection area of the dust removal electric field anode is larger than a discharge area of the dust removal electric field cathode, so that an asymmetric electrode attraction force is produced between the electrodes, to reduce electric field couplings.
