Douglassville, PA (Feb, 2014) – NESTEC Inc. has announced that it has expanded its product offering with a unique hybrid concentrator technology.
The addition of the technology allows NESTEC to offer a complete line of pollution control equipment to companies in manufacturing facilities, such as Semiconductor, Miscellaneous Organic Chemical Manufacturing, Miscellaneous Coating Manufacturing, Reinforced Plastic Composites, Painting processes, Automotive, and others that utilize Volatile Organic Compounds (VOC) and Hazardous Air Pollutants, (HAP) in their products, where low concentration, high volume (LCHV) room ventilation exhaust becomes a major economic issue in meeting their emission control requirements.
“As plant managers have already realized, the cost of natural gas continues to increase and their low efficiency thermal oxidation equipment is burning up their profits faster than they can produce them.”
The low concentration, high volume (LCHV) VOC/HAP process exhaust streams substantially increase the capital and operating costs associated with most air emission control equipment. As plant managers have already realized, the cost of natural gas continues to increase and their low efficiency thermal oxidation equipment is burning up their profits faster than they can produce them.
To meet both air emission requirements and minimize operating costs, NESTEC is now able to offer a hybrid concentrator and regenerative thermal/catalytic oxidizer (RTO/RCO) system. The hybrid system virtually eliminates the need for additional auxiliary natural gas. The energy produced from the combustion of concentrated VOC/HAPs provides nearly all of the energy to self sustain the operation of the system.
The Hybrid System
The basic system operates in the follow fashion. The low concentration, high volume (LCHV) process streams are directed to a two (2) stage pre-filter system, if required, to remove any potential dust and dirt prior to the concentrator. These units include monitoring and easy access to clean and replace filters as needed. After the filters, the process then enters into the zeolite rotating concentrator disc, where zeolite media adsorbs and removes the incoming VOC / HAPs, before the clean air is discharged to atmosphere through an induced draft, low horse power fan to a common stack.
A slipstream from the LCHV process flow, after the filtration, if included, is utilized to cool each concentrator zeolite disc after the higher temperature de-sorption process. This stream is then directed to an air to air heat exchanger where it is preheated by the hotter exhaust from the RTO/RCO unit, before it is returned to the concentrator disc to strip the disk of collected VOC / HAPs. The air stream with its concentrated VOC/ HAPs is then sent to the RTO/RCO unit for oxidation into CO2 and water.
This type of hybrid system, with high thermally efficient RTO/RCO units (95–96 percent thermal energy recovery), increased reliability, maximized up-time design, and short installation with shop assembled skid mounted modular units, make it possible for industry to remain in regulatory compliance while continuing to turn a profit.
NESTEC offers a broadest range of air emission control technology and systems. Each NESTEC system is configured to suit the specific industry application and process conditions. Emerging processes and innovative engineering solutions are integrated into these systems to maximize efficiency and minimize operating costs.
