| Summary: | Geothermal has been utilized as one of alternative energy source in Indonesia since 1983. Until 2008, Indonesia has utilized 1052 MW from total potential 27140 MWe of geothermal energy source. Utilization of geothermal <br />
<br />
<br />
energy could be optimized by constructing geothermal production facility. In this construction, mechanical aspect of piping system design must be conducted in <br />
<br />
<br />
order to prevent any failures. <br />
<br />
<br />
In this final project, pipe hydraulic analysis based on simulation using Hysys program, pipe sizing analysis, material selection analysis based on corrosion potential, and pipe stress analysis on Cluster 24 Lahendong Unit IV <br />
<br />
<br />
geothermal steam production facility has been conducted. Pipe stress analysis has been conducted using Autopipe program based on ASME B31.1 Power Piping Code. <br />
<br />
<br />
The results of hydraulic analysis showed that pipe size which has been chosen will produce steam fluid which will fulfill PLTP (electricity generation) requirement with pressure 8,85 bar and temperature 175,1 oC to PLTP III as well as pressure 8,79 bar and temperature 175,0 oC to PLTP IV. For material selection, carbon steel API 5L Grade B has been chosen with corrosion rate prediction 30 mpy without stress corrosion cracking potential. For stress analysis, bend and support modification for piping system is required because of the piping system incapability to hold expansion and earthquake loads. For parameter study in pipe stress analysis, failures would occur if wellhead moves 0,45 m upward or 0,48 m downward, saturated pressure increase up to 14,2 bar with saturated temperature 195,7 oC, wind velocity exceeds 700 km/h, and earthquake load exceeds 0,4 g. |
