Retrofit of Integrated Waste Gas-to-Energy Units by Conceptual Design Method

Thermal oxidation represents an efficient and reliable technology for processing industrial waste gases containing combustible pollutants, for example, Volatile Organic Compounds. Thermal oxidation units (or waste gas-to-energy units) enable the heat utilization of the waste gases, which thus become a promising energy source. This is, however, very energy-intensive process requiring a huge amount of primary fuel, which is dependent on the heat recovery efficiency. This paper presents a straightforward and fairly accurate graphic-numerical method for Energy Retrofit of waste gas-to-energy units providing formulas for estimation of maximum reachable fuel savings and tools for the design of specific technological modifications, which results in the increase of the heat recovery efficiency, energy demand reduction, operational costs savings and environmental pollution mitigation. The method is further applied to Energy Retrofit of a standard industrial unit and a modern compact unit for thermal processing of waste gases. Finally, the developed method´s accuracy was successfully verified by the comparison with non-linear simulation of both studied industrial units.
