Catalytic oxidation system for finishing facility

AIR pollution control specialist AirProtekt has supplied, installed and commissioned turnkey air pollution control equipment to abate VOC fumes and odours from three solvent based spray painting booths and baking ovens at an aircraft component finishing facility. The Honeycat ® concentrator catalytic oxidation air pollution control and energy saving system treats the exhaust gases from the component finishing process to give a maximum running flowrate of 12,000Nm 3 hr-1 at a temperature of 20°C with a normal VOC concentration of 170mg Nm-3 MEK, xylene and toluene. The solvent laden gases are ducted and pulled through a rotary honeycomb zeolite wheel. The solvent from the process stream is adsorbed onto the hydrophobic zeolite in the honeycomb wheel. The clean gases are then transported into the main process fan inlet and pass via an exhaust stack to atmosphere. The concentrator’s honeycomb wheel zeolite rotor is continuously rotating to adsorb the VOCs, which then pass into the regeneration zone where the VOCs are removed by a small volume of preheated air, which then passes into a small Honeycat catalytic oxidation system. The combination of the VOC concentrator and Honeycat catalytic oxidation system means very large process exhaust flows containing low quantities of VOCs can be treated by a cost effective system. This type of system means that only 5% of the process flow is treated by the Honeycat OP Srl’s Unispeed USFL 90/37 is a machine for 37° and 90° orbital flaring of hydraulic rigid pipe ends with ISO 8434-2 and ISO 8434-3 fitting systems. Designed to be practical and easy to use, the machine requires only one tool change to carry out flaring operations. This reduces processing time to a minimum, since it is carried out easily and without additional equipment. The machine uses a cold orbital forming process to create a

catalytic oxidation system, which represents a reduction of 20:1. With the increased VOC concentration the operating cost for the total system is very low when compared with alternative systems. “AirProtekt’s solution to the challenges posed by this aircraft component finishing application has now enabled the new production facility to comply with statutory emission regulations for VOCs,” explained Trevor Lawton, AirProtekt’s managing director. “The new installation also extends the company’s global environmental policy. The Honeycat concentrator catalytic oxidation air pollution control and energy saving system also benefits from much lower capital and running costs compared with an alternative thermal oxidation plant solution.” flat and smooth sealing surface at 90° and 37° with a suitable rugosity for the O-ring seal. By doing so, it avoids the formation of processing signs that can occasionally occur with common axial deformation processes. The system is compliant with the pipe flaring requirements regulated by SAE and ISO standards. The various adjustment and configuration possibilities of USFL 90/37 allow any flaring diameter and

Overall, the AirProtekt is a low energy solution for both start up and online running conditions. The compact catalytic oxidation system also requires only minimal upgrades to a customer’s infrastructure. The system features lightweight construction, requires no compressed air or natural gas, and is very quiet in operation. AirProtekt’s engineering solutions are tailored to address specific local emission requirements but are also specified to comply with national and international regulations as well as detailed global company-specific guidelines or operational procedures.
