Abstract
A Volatile Organic Compound (VOC) mitigation system employs a combination of technologies coupling VOC laden exhaust with a reciprocating engine and generator system (Combined Heat & Power (CHP) System) with heat recovery to destroy the VOC emissions and generate electric power and useful thermal energy.
Claims18
A system for mitigating volatile organic compounds (VOC) emissions generated as a by-product of a production process while producing energy therefrom, the system comprising:
- an exhaust system for expelling an exhaust stream as part of a production process;
- a detector located in a path of the expelled exhaust stream for determining a concentration of VOC in the expelled exhaust stream and passing the expelled exhaust stream directly to a combustion engine when a determined concentration of VOC's therein is above a predetermined threshold level;
- and
- a combustion engine for receiving the expelled exhaust stream containing VOC's and reducing the expelled exhaust stream containing VOC's to usable mechanical energy and heat energy components.
A combined heat and power (CHP) system for mitigating volatile organic compounds (VOC) emissions generated as a by-product of a production process while producing useable energy therefrom, the system comprising:
- a first detector located in a path of an exhaust stream expelled during the production process for determining a first concentration of VOC in the expelled exhaust stream and generating a first VOC concentration signal indicative thereof;
- a VOC concentrator, located in a path of the expelled exhaust stream after the first detector;
- and
- a combustion engine for receiving the expelled exhaust stream from the VOC concentrator and reducing the expelled exhaust stream to usable mechanical energy and heat energy components;
- wherein the VOC concentrator is switchable between a pass-thru state and a concentration state responsive to a value of the received first VOC concentration signal.
A process for mitigating volatile organic compounds (VOC) emissions generated as a by-product of a production process while producing energy therefrom, the process comprising:
- receiving an exhaust stream generated during the production process at a VOC concentration detector and generating a VOC concentration signal indicative of a concentration of VOCs detected therein;
- receiving the VOC concentration signal at a controllable fuel source;
- receiving at a combustion engine, the exhaust stream and fuel from the fuel source, wherein at least one of fuel amount, type and flow rate is adjusted by the controllable fuel source responsive to the VOC concentration signal prior to providing fuel to the combustion engine;
- and
- producing, by the combustion engine, mechanical energy and heat energy.
