.jpg) | Thermox™ thermal oxidizers efficiently react Hydrocarbons (HCs) and Volatile Organic Compounds (VOCs) with oxygen in the air to form naturally occurring carbon dioxide and water vapor (HC + O2 + heat -> H2O + CO2). This reaction occurs when the air is heated to a sufficiently high temperature, typically 1400 - 1600°F (760 - 870°C). The fuel needed to heat the process stream to the oxidation temperature is greatly reduced in a Thermox system by using a recuperator or "preheater". With or without a preheater, the Thermox is capable of achieving the highest VOC, hydrocarbon and odor destruction of any of our technologies. The Thermox is also designed to provide reliable performance over a wide range of process variables.  | ||||||||
.jpg) | Thermox™ Recuperative Thermal Oxidizer Thermal Recuperative Oxidizers have been used for many years as a straightforward and effective means of destroying organic fumes in process exhaust gas. Thermal Oxidizing Systems can be applied to a wide variety of processes. Thermal Oxidizing Systems are often the technology of choice because of durability and adaptability over a wide range of operating conditions. The basic form of an oxidizer is a retention chamber and a supplemental heat source (burner). This type of thermal oxidizer is often referred to as an ‘afterburner’ see vertical unit. Adding a heat exchanger (recouperator) to reduce fuel use, it becomes a recuperative thermal oxidizer as seen in the foreground. | ||||||||
.jpg) | Why Air-Clear Thermox™ Recuperative Thermal Oxidizers. • Proven technology for oxidation of volatile organic compounds (VOCs) and for the control of odorous emissions with greater than 99% efficiency! • Recognized as the Best Available Control Technology (BACT) and Maximum Control Technology (MACT) for many industrial process. • Thermox™ Recuperative Thermal Oxidizers reduce energy costs by using a pre-heater ( heat exchanger ) to recover the heat from the post oxidized air to preheat the incoming process air. Further savings can be gained with a secondary heat recovery or ‘economiser’ Recuperative – meaning to recover and restore • The Thermox ™ Thermal Oxidizer is designed to provide reliable stable operation over a wide range of process conditions. • Small or large flows as well as multiple sources feeding one thermal Oxidizer can utilize thermal oxidation to control emissions. The Thermox ™ is also an excellent choice for intermittent ON-OFF use. • Thermal oxidizers can rapidly adjust to changes in VOC loadings. When equipped with a High Temperature Bypass Valve (HTBV). • Flexibility - Custom design-meets your specific project objectives at the lowest cost possible. The chemical industry has utilized oxidation for several years. Safety issues and the corrosive nature of the emissions make online reliability extremely important. AC experience with HAZOP reviews insures a smooth interface between the process and APC system. | ||||||||
.jpg) | Best Value Air-Clear relies on a network of world class providers of specialty components selected by our Engineers for integration into cohesive system. Suppliers are selected based on the design features, quality of construction, and cost competiveness. In addition Air-Clear Fabricates internally, eliminating the cost mark ups passed on by subcontracted fabricators. Several extraction wells are efficiently controlled by one thermal oxidizer. Since soil remediation projects have a finite life (1-5 years) these wells are controlled by a leased unit, saving capital cost. | ||||||||
.jpg) | Post commissioning support Worldwide Capability- AC has completed projects worldwide. Air-Clear supports these projects on an ongoing basis by a combination of in house resources, remote diagnostics and localized support personnel. • FAT - Factory Acceptance Test – reduces commissioning and start up time by running a thorough diagnostic system check PRIOR to shipment • Air-Clear has extensive knowledge of various materials of construction and metallurgies to insure long-term system performance and reliability, especially when working on Chlorinated applications. This view of a ‘shell and tube’ heat exchanger prior to the exterior casing offers a unique view of the interior | ||||||||

Additional heat is recovered from the exhaust stack by an air / air exchanger is used to heat ambient air which is returned back to the dryer. This allows for the solvent in the process exhaust to provide the heat for the dryer | ||||||||
.jpg) | How Air-Clear Thermox™ Recuperative Thermal Oxidizers Works • Prior to ignition, the air inside the oxidizer must be purged to extract any residual gas that may have leaked into the chamber. The purge is controlled with a timer; this insures the proper volume of fresh air. The blower, in conjunction with an ambient air valve, forces clean air through the system. To prevent the possibility of drawing additional contaminated air from the process, an isolation valve closes off the process and permits ambient (fresh) air to enter the system. A 15,000 CFM unit is used interminably to control a wide variety of emissions from a burn testing laboratory. | ||||||||
.jpg) | System Controls The "brains" of the Air-Clear Thermal Oxidizers are the instrumentation and controls. PLC's - Program Logic Controllers are available with input and output (I/O) options and electrical configurations that make them ideal for a wide range of applications. A thermal recuperative oxidizer is erected at Air-Clear for it’s FAT. This unit went through a rigorous operational test, common for the Pharmaceutical industry. | ||||||||
