Abstract

PT Pertamina geothermal energy (PGE) Ulubelu uses jetspray-type condensers with the task of changing the vapour phase from turbine (steam tubin) to liquid. Condenser input fluid is the output of turbines (steam and non condensable gas), operating at a constant pressure of 0,08 bar and an average temperature of 28oC. Evaluation of condenser performance is based on the temperature and flow rate (condenser entry fluid and cooled water flow rate) against the value of thermal efficiency and effectiveness. The highest effectiveness value of 79,4% occurred when the Qaktual value was 10,891oC, while the lowest effectiveness value of 78,2% occurred when the Qaktual value was 10,306oC. The highest condenser thermal efficiency occurred in week 4 at 52,3% with Qair 441,149,944.2 kJ/h. Qair value of 417.424.072,6 kJ/h resulted in a condenser thermal efficiency of 49,5% in the first week. The calculation results were then visualized using a graph showing when Q was raised from 4,17.108 kJ/kg to 4,4.108 kJ/kg condenser efficiency increased by 0,6%.

Abstract

The small scale physical model of drum type was set-up to obtain the effect of water cement ratio (w/c) to pile capacity and original soil. The simulation of the process of providing bored piles model, soils model, installation and tests (pile loading tests and direct shear tests) under different water cement ratio of mortar and various moisture content of clay were done. The results reveal that the higher water content of original clay the bigger friction resistance, α value as clay soil is softer and the optimum w/c-ratio (w/c = 0,4) provides more pile capacity. It is understandable that water plays an important role, contributes to the change of surrounding clay properties. The improvement of Su ( % increase) due to compaction of concrete in bored pile, migration of moisture and reaction with surrounding clay leads to take benefit of design and construction of bored pile in clay soil for the sake of efficiency and stability.

Abstract

The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process was developed using the Python programming language. It is featured with a GUI (Graphical Users Interface), to facilitate user interaction. The program is designed to calculate the composition of gas producer with 6 components involved, they are CH4, CO, CO2, H2, N2, and H2O. The design of computational algorithms for calculating non-stoichiometric thermochemical equilibrium models is converted into Python code. The GUI consists of input and output facilities in form of tables and graphs of calculation results. The input facility is designed in such a way that the user can vary the gasification temperature and the equivalent ratio. The calculation results of the simulation program are verified with the calculated data manually to ensure that there are no errors in the algorithm or writing program code. It is also compared with the experimental data from previous studies to see the accuracy of the thermodynamic model in predicting the composition of gas producer. The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process can predict the composition of producer gas with a fairly good level of accuracy and can be used as a learning medium in studying thermodynamic equilibrium.
