Regenerative Thermal Oxidiser (RTO)- VOC abatement technology
LESNI has extensive experience of design, manufacture and supply of process waste air thermal oxidisers, or catalytic abators which safely and effectively destroy waste off-gases and VOC emissions from a diverse range of industries. This includes design and supply of turnkey packages based on either two or three bed chamber oxidisers, as well as waste to energy incinerators. The range includes also; Recuperative thermal oxidisers, Catalytic thermal oxidisers, Regenerative Thermal oxidisers, Concentrators, SCR DeNOx systems.

Ethylene Oxide, (EO abator) - ETO Catalytic Abatement
LESNI continues to improve their "state of the art" balancer & catalytic abator solution for treating all ethylene oxide toxic vent emissions from the sterilisation process of medical devices.

ODS Abatement, Fridge Recycling - Destruction of CFC & Pentane
LESNI combined CFC recovery plant provides the ultimate solution for "WEEE" and the treatment of Ozone depleting substances generated from defragmantation and recycling process of fridge freezers to the highest levels of recovery that any other technology can provide. Furthermore, the well proven technology currently offers the only complete solution for the safe conversion of "ODS" controlled substances like R11, R12, and other refrigerants; as well as other hydrocarbon refrigerants such as Pentane, IsoButene that are used in modern fridges. The system meets all highest standards and does not generate any hazardeous liquid waste.

Wet Scrubbers (spray, packed, venturi gas scrubbers)
LESNI design and supplies a range of wet scrubbers for waste gas treatment, process vacuum systems and waste air vent extraction applications.

Activated Carbon & Solvent Recovery- Adsorption of VOC & Odours
LESNI offers complete purification systems for solvent recovery on activated carbon, also for VOC purification and Odour control. Solutions are generally designed to meet requirement and total capital and operating cost.

Odour control & VOC abatement
LESNI supplies many technologies for VOC and odour control; generally the systems are developed for specific application where know-how and process innovation are guaranteed. The regenerative thermal oxidiser system developed here demonstrate innovative approach to treat waste gas from sludge drying, pet food and animal feed byproduct, or fish and meat rendering applications. The final result is a clean and pure air from the processing plants with no further odours emanating from the buildings or the process, whilst reducing running cost and eliminating secondary waste effluents.

Soot trap catalytic filters
Genset exhaust is creating a major environmental concern with toxic fumes and soot generated at random depending on the age and model of the diesel genset. The purposely constructed catalytic soot trap abator was developed for use on Stationary Genset Diesel Engines up to 3 MW where sulphur content in the fuel could be as high as 350 PPM.
