Environment & Power Systems International and their business consortium offers turn-key engineering and design, installation, commissioning and after-market services for the VOCGEN CHP solution. VALUE PROPOSITION Our environment and power solution creates a superior cost savings model for over 100 discrete industrial categories subject to the requirements of the Clean Air Act . VOCGEN CHP replaces the life-cycle costs of traditional volatile organic compound (VOC) air pollution control equipment. This enhanced cogeneration economic model is realized by a quick return on capital investment united with significant reduction in plant operating costs for the life of the project, estimated at >20 years. The Company’s products are sold at competitive air pollution control market-based prices.

VOCGEN by Environment & Power Systems International are small scale, highly robust simple cycle industrial gas turbine power generators that cogenerate 0.560 MW(e) output power and an average 6.5MMBtu/hr high quality heat energy. When configured in combined heat and power (CHP) and VOC abtement applications, VOCGEN can acheive overall system efficiencies (electricity and useful thermal energy) greater than 80%.  

VOCGEN is an energy efficient solution for EPA-regulated industries. Think combined heat and power (CHP) economics plus the elimination of the life cycle costs associated with traditional VOC air pollution control equipment.  

The additional work output (voc destruction) by the gas turbine produces an enhanced economic model, resulting in greater energy operational cost savings compared to the standard CHP economic model.  A simple return on investment period for a vocgen chp system is typically less than 2 years.

Our approach to the VOCGEN niche market is a side by side comparison of capital and operational costs between a VOCGEN CHP system and the user's existing air pollution control system. Request a project questionnaire and we will work with you to complete a Level 1 Feasibility Assessment. VOCGEN CHP systems replace existing air pollution control equipment subject to Clean Air Act Title V Operating Permits including carbon adsorption, direct flame and regenerative thermal oxidizers (RTO).

VOCGEN gas turbines operate on primary pilot fuels, typically natural gas. VOC-laden process air emissions are utilized as a secondary fuel that contribute to the operation of the gas turbine.

Volatile organic compound (VOC) emissions are generated in fuel storage and transfer operations and processes that use hydrocarbon solvents in manufacturing, petrochemical and the synthetic organic chemical manufacturing industries (SOCMI).

A single engine genset can process 6,200 cubic feet per minute (CFM) voc-laden emissions at ISO conditions; 15 deg C (59 deg F) ambient temperature; 60% relative humidity; and ambient pressure at sea level.

Multiple gensets sharing a common inlet air ductwork or header can manage larger air volumes, or voc concentrator technology can be used to reduce air volumes and increase concentrations of voc, which can be managed by one or two gensets.

Overall system energy efficiencies are up to 90% with carbon emission reductions over 50%. Cost benefit analyses typically result in $450K to over $1 million (USD) in annual operational cost savings.  This is achieved when applied as industrial air pollution control systems and the generated electricity and waste heat offset part of the utility-provided energy requirements of the facility.

Additional operational cost savings are possible if the equipment is synchronous and/or black start capable, eliminating standby and backup diesel generators typically deployed at the user's facility.

Our gensets are skid-mounted, portable environmental enclosures designed to build scalable air pollution control and combined heat and power (APC/CHP) systems for industrial applications.
