| Abstract |
Optimization of steam pipeline has been conducted using manual calculation and supported by using a simulation of computational fluid dynamic software. Based on the pressure drop analysis, the replacement of T-Junction with Y-Junction would be beneficial as the pressure on the header would be 6.68 kg/cm2, which means that it is above the minimum working pressure requirement. If this scenario is implemented, all of the minimum requirement operating parameter would be fulfilled, where, Poperation > 6.5 kg/cm2, Toperation >161oC, and >2750 kJ/kg for enthalpy and it is the best scenario to have minimum energy loss. As for heat loss, by using manual calculation, the obtained value is 2003.6 kJ/s along the pipeline. The value of heat loss is used as an input of heat flux in the simulation, and therefore the temperature on the header is 164.2 oC if the pipeline use T-Junction and 165.7 oC if the pipeline use Y-Junction. It is must be concered that, although the temperature is above the minimum operating temperature condition, theoritical, with pressure of 6.54 kg/cm2, it require minimum temperature of superheat 169 oC which will leads to saturation temperature of 167.8 oC. It means that a higher temperature is needed to ensure the steam quality. Increasing value of wetness could be hazardous for the turbine that will leads to water droplet and cause erotion. From the mass balance calculation, there is no significant change of flowrate, where the upstream flowrate from all of the wells is 281.27 ton/hour become 280.259 ton/hour. |
