Efficient Air Pollution Control in the Building Materials Industry
Envanio designs and manufactures industrial air pollution control solutions tailored to the specific requirements of various sectors within the building materials industry. Our custom-designed systems significantly help you cut emissions, maintain full regulatory compliance and drive more energy-efficient and sustainable production.
Overcoming Key Challenges of the Building Materials Industry
Ensuring Maximum System Availability
If an air pollution control system fails, production can grind to an immediate halt, resulting in significant costs. Envanio designs heavy-duty, highly reliable systems backed by rapid, comprehensive lifecycle support to maximize uptime.
Stricter and Evolving Emissions Limits
The global building materials industry must comply with diverse regional standards and adapt to ever-tightening emissions limits. To help operators stay ahead, Envanio delivers flexible, future-proof systems and retrofit solutions.
Balancing High Energy Use with Carbon Neutrality
The production of building materials is energy-intensive and faces significant pressure to decarbonize. Envanio bridges this gap with electrically heated RTOs and advanced heat recovery options to ensure clean exhaust with a minimal carbon footprint.
Complex and Dynamic Process Conditions
Variable VOC loads, shifting production schedules, and changing emission compositions require flexible and resilient equipment. That’s why Envanio designs systems that have proven effective in complex and dynamic process and operating conditions.
Key Building Materials Industry Applications Requiring Air Pollution Control
Rotary kilns and furnaces generate large volumes of exhaust gas containing a wide variety of pollutants from both raw feedstocks and alternative fuels. In these demanding thermal processes, combining innovative technologies with field-proven abatement methods is essential to achieving the lowest possible clean-gas emission levels.
Suitable Systems for the Building Materials Industry
Air pollution control requirements in the building materials industry vary based on your specific production process, exhaust air flow rates, and regional regulatory standards. Envanio offers both standardized and custom-engineered systems designed to meet your specific operational needs and adapt to changing production parameters, drawing from a broad portfolio of field-proven technologies.
Regenerative Thermal Oxidation
Regenerative thermal oxidation (RTO) is a highly efficient process that cleans industrial exhaust by destroying hazardous air pollutants (VOCs and HAPs) and eliminating unpleasant odors. By using internal ceramic heat exchange media, the system traps and recycles its own heat, making the entire purification process incredibly energy efficient.
Electric Regenerative Thermal Oxidation
Envanio's electrically heated regenerative thermal oxidizer (eRTO) combines high VOC destruction efficiency, operational reliability, and exceptional energy performance. By using electric heating elements instead of gas-fired burners, the system avoids combustion-related byproducts and significantly reduces NOₓ emissions. The result is a cleaner, more sustainable solution for industrial air pollution control.
Catalytic Hot Gas Filtration
Envanio’s catalytic hot gas filtration is based on an integrated 3-in-1 process for industrial hot gas and exhaust air purification. Rigid, high-temperature ceramic filter elements enable the simultaneous removal of particulate dust, heavy metals, sulfur oxides (SOx), and nitrogen oxides (NOx) from process exhaust in a single compact system.
Carbon Adsorption
Envanio’s activated carbon adsorption is based on the physical adsorption process to purify industrial process air of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from industrial exhaust air, with the option for solvent recovery. In our regenerative systems, both the adsorbent and solvents are recovered for reuse, while in non-regenerative systems, the spent activated carbon is safely disposed of or replaced along with the captured pollutants.
Wet Scrubbing
Envanio’s wet scrubbers rely on absorption for the wet separation of inorganic compounds, particulates, mist, and acidic gases. During the regenerative or direct-fired thermal oxidation of halogenated hydrocarbons or sulfur compounds, substances such as hydrogen halides or SOx are generated, which must be scrubbed from the exhaust air in a downstream wet scrubber.
Electricity from Waste Heat with Cyplan®
Cyplan® by Envanio converts industrial waste heat from decentralized heat sources into CO₂-free electricity and usable heat. The flexible ORC technology harnesses heat sources ranging from 194 °F to 1112 °F, improving energy efficiency, reducing energy costs, and integrating seamlessly into existing processes.
