S. Abdullah, - (2021) Modeling of SO2 and CH4 Emission Distribution in the Area Mataloko Geothermal Power Plant, East Nusa Tenggara, Indonesia.
Abstract
The Mataloko geothermal system in Ngada-Flores Regency, East Nusa Tenggara, is located in three active volcanic mountains (Inerie, Ebulobo, and Inielika). The contribution of high levels of CH4 and exhaust emissions of SO2 due to its utilization as a geothermal power plant (GPP) impacts the environment. This study aims to analyze and spatially model the distribution and impact of SO2 and CH4 gas levels in the Mataloko GPP area. The quantitative descriptive method was used through direct measurement at gas wells and laboratory testing. The results showed a tendency to increase SO2 levels in the MT-4 gas-well with levels of 8.00 ppm exceeding the quality standard, which could disturb the environment in the Mataloko-GPP area. Impact of high SO2 will experience dry sediment because it is not combustible in the air, then it will drop slowly to be absorbed by soil and plants. Droplets of acid gas blown by the wind and left on trees and buildings are even inhaled into the breath. In addition, the advantages of model with surfer 12 software can help identify the distribution of SO2 and SO4 emissions in the generating area.
