Abatement of Vapor Phase VOCs
ECT2 has developed advanced technology for the clean, safe, efficient and cost effective abatement of vapor phase volatile organic compounds (VOCs), one of the primary elements of air pollution generated by the Chemical Process Industries (CPI), including chemical plants, refineries, and factories that use toxic chemicals in the course of their production processes. The traditional methods of VOC abatement are thermal oxidation or adsorption via Granular Activated Carbon (GAC). ECT2’s has developed a patent-protected adsorption technology that allows for more efficient, compact systems that can run longer than the competition.
Our lightweight vapor phase VOC abatement solutions incorporate our patent-protected polymeric synthetic resin technology and feature a modular design, small footprint, and ease of installation and access. These systems offer continuous operation to accommodate processing requirements, and media capacity is renewable in place by regeneration, supporting sustainability programs with options for product recovery, energy generation or both. Predictable, repeatable performance can be leveraged to streamline compliance management programs and reduce compliance effort over time. Low first cost and very low operating cost provide rapid investment return and reduced lifecycle cost.
ECT2’s fixed bed systems are compact, lightweight, easily-installed, self-contained vapor treatment systems for continuous or intermittent treatment of process vents or other lower-flow environmental applications with high-concentration influent conditions. They use a polymeric medium that selectively removes organics and has a high loading capacity, going years, rather than weeks or months, between media change out and overcoming other concerns with GAC, such as O&M cost, compliance, process disruption, legacy liabilities, and sustainability. These adsorptive systems are inherently safer than thermal oxidizers and remove the need for potential secondary treatment.
ECT2’s high-flow solutions are designed to operate under continuous service conditions for the removal, destruction, or recovery of contaminants such as organics, aromatics and fragrances from facility air discharges, where extensive removal and energy efficiency are a must. These continuous moving bed (CMB) air treatment systems can be configured to handle flows of 100,000 SCFM or more, with a neutral energy footprint. The systems typically include a fluid bed adsorber to continuously capture the VOCs from plant emissions, a fluid bed desorber to simultaneously renew the media capacity, and a small thermal oxidizer to destroy the organic vapors captured during treatment. Inherently simple, highly reliable, and requiring very little routine maintenance and associated cost, these systems are an integral part of an overall effort to improve reliability, reduce compliance costs, and improve margins.
ECT2’s CMB systems represent a new approach to VOC abatement, offering an alternative to Regenerative Thermal Oxidizer (RTO) units. Complexity and fuel and electricity requirements not only make RTO units unreliable and costly to operate but also result in them generating CO2 emissions of their own. ECT2’s CMB systems concentrate captured VOCs by up to 90 fold, resulting in concentrations that are sufficient to sustain oxidizer operations without supplemental fuel. This combination of oxidizer optimization and elimination of the requirement for supplemental fuel reduces CO2 emissions related to air compliance to nearly zero and reduces energy cost to a fraction of what was previously required.
