Abstract: A treatment apparatus for treating an effluent gas includes a combustion chamber; a burner; an inlet for receiving secondary combustion air; an exhaust gas outlet for outputting exhaust gases from the combustion chamber; and a heat exchanger. The heat exchanger is configured to exchange heat between a first fluid and a second fluid flowing through respective first and second fluid flow paths. The first fluid flow path is connected to the inlet and the second fluid flow path is connected to the outlet such that the exhaust gases received at the outlet flow into the second fluid flow path. The heat exchanger comprises a fluid flow communication path for providing a path for flow of a portion of the exhaust gases from the second fluid into the first fluid; and at least one inlet aperture for inputting the first fluid to the combustion chamber.

Abstract: Venturi Scrubbers are used to separate particulate from a large range of fluids. Many provide additional liquid and/or gas to drive the fluid and aid in the removal of particulate. The present invention provides a liquid ring pump through which the fluid to be treated is first passed and then exhausted, with additional work fluid to a Venturi scrubber such that the particulate can be separated from the exhaust fluid.

Abstract: Aspects and embodiments relate to plasma torch device component monitoring, a plasma torch device component monitoring system and a plasma torch device including such a monitoring system or suitable for use with such a system. The monitoring method comprises: collecting electromagnetic radiation generated by a plasma torch in a plasma torch device; analysing the collected electromagnetic radiation generated by the plasma torch; comparing the analysed electromagnetic radiation generated to known electromagnetic radiation associated with one or more components of the plasma torch device; and triggering one or more actions in the event that the analysed emission differs from the known emission. Such a monitoring method can allow for ameliorative action to be taken in the event that degradation of one or more components forming the device is detected.

Abstract: The abatement apparatus includes a porous element at least partially defining a treatment chamber and through which treatment materials pass for introduction into the treatment chamber for treatment of an effluent gas stream; and an infra-red heating device operable to emit infra-red energy to heat the porous element which heats the treatment materials as they pass through the porous element into the treatment chamber. In this way, infra-red energy, rather than combustion, can be used to raise the temperature within the treatment chamber in order to treat the effluent gas stream. This allows the apparatus to be used in environments where no fuel gas exists or where the provision of fuel gas is considered undesirable. Also, heating the treatment materials as they pass through the porous sleeve, rather than simply using radiant heat to heat the treatment chamber enables significantly more energy to be imparted into the treatment materials.

Abstract: Liquid ring pumps are used to pump a variety of fluid types. Corrosive fluids are easily handled by the work fluid but can cause corrosion of pumping mechanisms. The present invention provides a magnetically driven liquid ring pump with corrosion resistant pumping mechanisms which achieves a longer time between service intervals.

Abstract: Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable.
