Method for Estimating Size-Specific Particulate Emission Inventories

Self Cite

Based on the well-established theoretical formulations of Calvert (1970) and Yung et al. (1978), graphical tools are developed for estimating the overall collection efficiency of venturi scrubbers under the specified design and operating conditions. Both graphical solutions deliver the accuracy of the original theoretical models, subject to the assumption of a lognormal input particle size distribution. The nomographs produced can be used by environmental engineers for performing convenient analysis of venturi performance and alternative design evaluations, and as part of a wider methodology for compiling particulate matter emission inventories. Combined with the graphical models developed in Part II, the present work sets the stage for conducting size-specific emission inventories (e.g., PM 2.5 , PM 10 , TPM) for sources controlled by venturi scrubbers.

“…To overcome this difficulty and enable planners to compile credible PM 2.5 , PM 6 , PM 10 , PM 15 , PM 30 , and/or TPM inventories for sources with lognormal particle size distributions, a generic method has been developed (Economopoulou and Economopoulos 2001). For controlled sources, this entails the development of graphical models enabling estimation of the overall efficiency, Ef, and of the output particle size distribution parameters, d p and σ p , for each type of control system used.…”

“…To address the need for size-specific particle emission inventories, a methodology has been developed, which can be used for compiling fast and credible PM 2.5 , PM 6 , PM 10 , PM 15 , PM 30 , and/or TPM inventories for sources with lognormal particle size distributions (Economopoulou and Economopoulos 2001). For the application of this methodology on controlled sources, easy to use models need to be developed for predicting the overall efficiency and the size distribution parameters of particles penetrating each type of control system used.…”

A general methodology is presented that enables rigorous estimation of the total collection efficiency and the size distribution of particles penetrating dust control systems. This methodology assumes lognormal inlet particle-size distributions and can be used with fractional efficiency formulations that predict, under such conditions, lognormal outlet particle-size distributions. Multimodal inlet particle distributions can be accommodated additively. This methodology is applied to Electrostatic Precipitator Systems LIST OF SYMBOLSA area of the precipitator collection plate, m 2 ; b width of the electrostatic precipitator, m;

“…In view of this, a general methodology has been developed (Economopoulou and Economopoulos 2001), that enables fast and credible estimation of size-specific particle emissions (PM 2.5 , PM 6 , PM 10 , PM 15 , PM 30 , and/or TPM) from uncontrolled and controlled sources with lognormal particle size distributions. For the application of this methodology, one needs a set of nomographs that yield the overall efficiency and the size distribution of penetrating particles for each type of control system used.…”

Graphical Analysis of the Performance of Venturi Scrubbers for Particle Abatement. Part II: Size Distribution of Penetrating Particles

Graphical tools are developed that provide convenient estimation of the size distribution of particles penetrating venturi scrubbers, based on the well-established theoretical formulations of Calvert (1970) and Yung et al. (1978). The graphical solutions, produced through functional analysis and numerical methods, deliver the accuracy of the original theoretical models under the specified venturi design and operating conditions, subject to the assumption of lognormal input particle size distribution. While Part I describes estimation of the overall particle abatement efficiency, the work in this article allows estimation of the size distribution of emitted particles. The generated nomographs can therefore be used as part of a methodology for compiling size-specific particulate matter emission inventories.
