ANALISIS EMISI GAS RUMAH KACA (GRK) DARI MESIN PEMBAKARAN DENGAN APLIKASI SANGEA DI PT. CHEVRON PACIFIC INDONESIA (STUDI KASUS PADA TURBIN GAS MINAS 10)

Abstract

This study analyzes the greenhouse gas estimation calculation for CO 2 and NO x (as
NO 2 ) emissions. Estimation is calculated using the SANGEA application which is based
on the fuel gas consumption and composition for the combustion engine. The estimation
calculations are then compared with the results of on a direct measurement by using a
continuous emission monitoring system (CEMS.) Furthermore, the estimation
calculation is referred to some related regulations to see if it meets with the standard, to
know the quality levels or “tier” and reliability of the SANGEA application used, also
to learn more on the strategy undertaken by emitters in managing GHG emissions. The
study methodology used is descriptive qualitative analysis by performing field survey to
learn how to perform direct measurements with continuous emission monitoring
equipment or CEMS in place (in situ) and how to calculate estimation emissions using
the SANGEA applications for the operation of combustion engines or turbines. The
result of this study shows that there are differences result between the SANGEA
calculation and CEMS direct measurement, where the SANGEA calculation result is
19.7 - 27.8% lower than the direct measurement and this difference result is still close
with the previous studies that have been done, 18.3 to 30.7%, which is becomes a
theoretical reference for this comparison calculation and direct measurement study.
