VOCs Recovery Energy-Saving Efficiency Decision and Case Study

Promote VOCs (volatile organic chemicals) and re-use recovered oil as secondary energy can reduce environmental pollution meantime bring lots of energy-saving and socioeconomic benefits. Related data shows that install VOCs recovery unit (VRU) can produce large quantity of energy-saving efficiency. However, China currently has no related energy-saving efficiency evaluation methods, which makes barriers for promoting VOCs technology. This paper lists the key elements that response for VRU energy-saving efficiency, provide computational formulas which focus on VRU recovery benefits, take a case study for example and calculation the energy-saving benefit that VRU can bring. From the data comparison analyzes the relationship between VRU recovery rate, emission limits and energy consumption. At very end of this paper, some suggestion for better setting emission standard also is given.
