Abstract
The present invention refers to a thermodynamic system and a method to quantify the amount of oxidized methane and estimate the biodegradation rate of petroleum hydrocarbons in the contamination source zone in real time. The biodegradation rate is used to estimate the time required to reach safe levels in the concentration of contaminants in the soil. The system comprises a set of heat flux transducers distributed in the soil, different planes, a cylinder and a station with energy autonomy. The method includes analyzing the raw data, eliminating outliers caused by eventual probing failures, calculating the temperatures and their gradients for each moment measured at each observation point, calculating the temperature interpolant parameters for each moment using the temperatures and point derivatives, calculating the internal energy of the soil and the heat fluxes for each moment, calculating the cumulative value of energy transmitted, using a mathematical model to adjust the parameters of the decay curve, and identifying if there is any temporal dependence on the decay rates.
