PSGAS Energy Saving

PT Perta Samtan Gas– Extraction Plant is one of the production refineries processing Natural Gas into Natural Gas Liquids (NGL) products as raw material for Liquefied Petroleum Gas (LPG) and Condensate.

In conducting production process, Extraction Plant utilizes several supporting facilities (utility system) for the best quality NGL products. Significant support facilities used in Refinery Extraction are Fuel Gas and Electricity which are the highest energy consumption in PT Perta-Samtan Gas (PSGAS). The fuel gas energy is mostly used as fuel for major equipment such as Gas Engine Generator, Solar Turbine, and Heater. Electrical energy is mostly used in refinery production processes to drive electric motors.


It can be seen that the most significant energy use is energy fuel that is equal to 71.96% of total energy use in processing Natural Gas Liquid (NGL). While significant energy users for fuel gas are located in the area of a��a��Feed & Lean Gas Compressor (Solar Turbine) and Gas Engine Generator (GEG). Energy efficiency activities that began to be done to reduce total consumption of fuel gas usage in Refinery Extraction is by installing fuel metering in every main equipment of gas fuel user. This is because the total fuel energy consumption is only read on the totalizer metering only so that the total fuel consumption is less accurate. Until now the installation of fuel metering is still on-progress, where the estimated completion at the end of 2017, so the calculation of energy efficiency can not be realized.

After discussing the problem, the result of the energy conservation activity that is considered appropriate to pass the reduction of electric energy consumption is by installing Variable Frequency Drive (VFD) in NGL Pump B and trying to start installing timer on the lighting inside the Extraction refinery.


From this innovation, the average energy usage intensity decreased by 133.152 KWh / Year or equivalent to 454 MMBTU / Year. Total savings earned from this program amounted to IDR 22,597,657.- / Year.
