Abstract

Demands for electricity and steam at the Arun LNG Refinery Gas Processing Facility are 158,400,000 kWh/year and 180 tons/hour of steam produced by 3 (three) units of Gas Turbine Generators (GTGs) and 3 (three) units of Heat Recovery Steam Generators (HRSGs) at the generating unit at Arun Gas Processing Plant. The problem with electricity and steam generations at present is the high gaseous fuel requirement, namely 13.14 MMSCFD to process 30 MMSCFD of gas sold. The scarce availability of spare parts and several time operation interruptions (blackout) are also problems in the existing plant. The purpose of this research is to build a new generation unit at the separated from the existing GTGs and HRSGs with more efficient electricity generation and steam generation units and high level of availability. Replacement is carried out based on analysis of various generation alternatives, namely new GTG units & HRSG and boiler unit, new Gas Engine Generator (GEG) units & HRSG and a boiler unit, and connection to PLN (State Electricity Company) electricity network + a boiler unit. The results show that the installation of new GTG units & HRSG and a new boiler would require the gas fuel of 12.88 MMSCFD, which is 0.26 MMSCFD less than that of existing generations, and offer the least electricity generation tariff of $ 0.221/kWh and steam generation tariff of $ 0.0019/ton using cash flow economic method. The installation can support the operation and gas production activities at the ArunGas Processing Plant until the end of contract for the next 19 years.
