Mass Balance Method Tracks Harmful Emissions

Current levels of harmful chemicals, including hydrofluorocarbons and chlorofluorocarbons are calculated and assessed by using the mass balance method. The data enables environmental scientists to predict future levels of emissions that contribute to the depletion of the ozone layer.
The mass balance method is employed to determine the difference between the starting amount and the ending amount of a substance such as refrigerant gas. How much of the chemical was in daily use and how much of it was discharged into the air may then be determined.
A somewhat complicated equation is used to calculate the mass balance method, with the amount of chemicals entering a process are added to the different avenues in which these chemicals are used. Incorporating waste and accumulation, the result equates to the final amount of substance entering the atmosphere. For example, in terms of the refrigerant gas, the calculation takes the starting amount, transformation through the cooling process and the waste amount.
Officials use the mass balance method to track the volume of substances used for a given function. This is broken down by how much enters and leaves a system and how much is stored within and this is the approach taken when accounting for pollutants.
The mass balance method is required by the EPA to monitor and track chemicals that have been identified as harmful contributors to air pollution, the deterioration of the stratospheric ozone layer and global warming. These chemicals include chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform and carbon tetrachloride. The calculation that determines the exact amount includes the total amount of materials entering the equipment or a system versus the amount leaving the system.
In simple terms, the mass balance method can be defined as inputs = output plus accumulation. The mass balance method is critical in designing and analyzing processes, such as refrigerant gas as it moves its way through various systems, including air conditioning, heating ventilation and AC or refrigeration. Whatever substances or chemicals enter or leave a system must be accounted for.
The mass balance method incorporates strict reporting requirements. Facilities will report venting of hydrofluorocarbons, chlorofluorocarbo

ns and records total inventory at the beginning and end of the reporting period. Any purchases of refrigerant and any changes in capacity that occurred in the reporting timeframe must also be accounted for.
The mass balance method incorporates several factors, such as the type and number of cooling equipment machines, refrigerant type, total refrigerant discharge and any leaks. The equation identifies mass flows that would have been difficult to measure otherwise, for example evaporated substances, leaks, or chemical reactions.
