REFINERY WASTEWATER EMISSION TOOL VERSION 1.0 (RWET)

Collection System

Air Emissions

1. Determine the critical inputs of the unit listed on the corresponding sheet of RWET and record them on appropriate sheet.

2. Determine the influent concentrations of the pollutants of interest and input them into the model.

3. Review the default values of the variables and constants and make site-specific adjustments if necessary.

4. Review the chemical properties sheet and make any site-specific adjustments if necessary.

5. Record the air emissions for reporting and copy the pollutant effluent concentrations as inputs to the next downstream unit.

6. Repeat this process for the next downstream unit.

The Refinery Wastewater Emissions Tool Version 1.0 (RWET) is an Excel-based model designed to help regulated facilities estimate air 

emissions from wastewater collection and treatment systems. Separate sheets in RWET represent individual components in a typical wastewater 

treatment system and can estimate emissions for that particular unit. Effluent concentrations from a particular component can then be used as 

inputs for the next downstream collection or treatment unit. The calculations are primarily based on those presented in EPA AP-42 but also 

include updates deemed more accurate in the literature. The equations are presented in Appendix B of the emission protocol document.

Each sheet is set-up with a series of critical inputs, constants/variables with default values, and outputs. The following procedure should be 

used to reliably use RWET:

CONSTITUENT DISCHARGE CONCENTRATIONS TO POTW (C0) CONSTITUENT CONCENTRATIONS AT POTW (C)

This sheet is used for facilities that discharge wastewater to a POTW only. 

Directions: 1) Input (yellow boxes) facility wastewater flow rate and flow rate at the 

POTW; 2) Input (yellow boxes) constituent concentrations in the facility wastewater. 

The outputs (green boxes) are the pollutant concentration after dilution in the POTW

wastewater. The treatment units of the POTW are then used to estimate air emissions 

using RWET.

CONSTITUENT INFLUENT CONCENTRATIONS (C0)

This sheet is used for uncovered equalization tanks only. Directions: 1) fill-in the input data (yellow boxes); review default 

variables and constant (yellow boxes) and change if necessary; 2) record air emissions (green boxes); and 3) record effluent 

concentrations (light blue boxes) for downstream process unit emission calculations.

boxes) and change if necessary; 2) record air emissions (green boxes); and 3) record effluent concentrations (light blue boxes) for downstream process unit emission calculations.

Biodegradation reactions are the same as other aromatic hydrocarbons: oxygenase addition of molecular oxygen to one of the aromatic rings (Boyle, 1992). Therefore, the known values for Benzene were substituted.
