Analyzing Greenhouse Gas Emissions in the Ohmic Heating Drying Process of Sour Orange Juice

Abstract

An ohmic heating device was fabricated. For the heating process in three input voltage gradients and three percent weight loss of the sample were selected. During the thermal process, the power consumption was calculated and then using the ratios of pollution in power plants, the amount of Nox, SO2, and CO2 in three Steam, Gas turbine and Combine cycle power plants was calculated. All experiments were performed in three replications using CRD statistical design and the results were analyzed using SAS software. The highest amount of Nox was first in the Gas turbine plant and then in the Combine cycle power plant and Steam power plant, respectively. The amount of SO2 in Heavy gas used in the Steam power plant is more than the other two power plants, and then the highest amount of SO2 is obtained in Gas turbine power plant and finally in Combine cycle power plant. Also, the amount of CO2 in the Combine cycle power plant was less than the other two types of power plants. In general, when the factors of ohmic voltage and weight loss percentage are considered for the ohmic process, natural gas and Combine cycle power plant create the best possible state.
