A device and method of simultaneously removing flammable gases and nitrous oxide are provided. The device includes a thermal oxidation chamber, a high-temperature resistant dust filter, and a catalyst chamber. The thermal oxidation chamber is configured to receive an exhaust gas from a process tool. The exhaust gas includes flammable gases and nitrous oxide. The thermal oxidation chamber has a first exhaust pipe to emit nitrous oxide and dust generated after the exhaust gas is thermally oxidized. The high-temperature resistant dust filter receives dust and nitrous oxide from the first exhaust pipe, wherein the high-temperature resistant dust filter has a filter fiber net and a second exhaust pipe, and the second exhaust pipe is configured to emit nitrous oxide. The catalyst chamber receives nitrous oxide from the second exhaust pipe, wherein the catalyst chamber has a nitrous oxide decomposition catalyst to decompose nitrous oxide into nitrogen and oxygen.

A plant and a method for the production of hydrogen and bicarbonate. The plant includes a gasifier, a reformer, a direct contact exchanger and an apparatus for the production of bicarbonate. The plant is suitable for receiving fuel, oxygen, water, carbonate, brine at the inlet and for producing hydrogen, bicarbonate and calcium chloride at the outlet. The plant uses a self-cleaning direct contact heat exchanger to cool the syngas downstream of the reformer and to produce the superheated steam that feeds the gasifier: this heat exchanger allows the production of hydrogen at low costs and in modular plants.

Apparatus and methods are disclosed. The apparatus comprises: an abatement chamber of an abatement apparatus which treats an effluent stream from a semiconductor processing tool to provide a combusted effluent stream having effluent particles; and a first atomiser located downstream of the abatement chamber, the first atomiser being configured to produce droplets having a droplet size based on a particle size of the effluent particles to be removed from the combusted effluent stream. In this way, the atomizer may produce droplets which combine with or adhere to the effluent particles which assists in the removal of the effluent particles from the combusted effluent stream.

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

A method includes volatilizing one or more compounds from tobacco, or reaction products thereof, into a gas stream and recovering at least one of the one or more volatilized compounds or reaction products from the gas stream. The method may be carried out in connection with a dry ice expanded tobacco (“DIET”) process where volatile tobacco compounds are recovered rather than incinerated as is typically done with current DIET processes.

A carbon nanotube production system is used for improving plant growth characteristics for a plant growing medium, for example soil in an agricultural field. The system includes an internal combustion engine, for example a tractor engine, which is arranged to combust a fuel mixture therein which includes a blend of fuels and additives including a carbon nanotube seeding material. The engine is operated in pyrolysis to produce exhaust emissions containing black carbon ultrafine and nano soot, for example by towing an agricultural implement across the agricultural field. At least a portion of the exhaust emissions is captured and conditioned to process the carbon soot into carbon nanotubes. The conditioned exhaust emissions and carbon nanotubes therein are then applied to the plant growing medium, for example by using the agricultural implement to incorporate the conditioned exhaust into the soil.
