Abstract

In any operating geothermal power plant, steam quality is one of the most important parameters being monitored. In the Bacon-Manito Geothermal Production Field (BGPF), an online steam quality monitoring system have been installed in two operating power plants which provides an accurate, efficient and continuous real-time data which is more responsive to the various requirements of the field operation. The system utilizes sodium as an indicator of steam purity. Sodium concentration is read by the flame photometer located at the interface after aspirating a sample of the condensed steam through a continuous condensate sampler. The condensate has been degassed through a condensate-NCG separator. The flame photometer analog signal is then converted by a voltage-to-current converter/transmitter and relayed to the processor which is located at the control center through electrical cable to give a digital sodium concentration read-out at the control panel. The system features a high and high-high sodium level alarm, a continuous strip-chart recorder and a central computer for data capture, retrieval, and processing for further interpretation. Safety devices, such as the flame-off indicator at the control center and the automatic fuel cut-off device along the fuel line, are incorporated in the system.

Simple interpretations of chemical transients in multi-feed, two-phase geothermal wells; Examples from Philippine Geothermal fields

Journal Article Ruaya, J; Solis, R; Solana, R; ... - Geothermics (International Journal of Geothermal Research and its Applications); (United States)

This paper reports that the main process responsible for the extreme variations in chloride concentrations in the water discharged by selected multi-feed, two-phase geothermal wells in the Philippines is steam addition brought about by fluid flashing in the formation or by a shallow and distinct steam zone. Correlation of enthalpy with chloride data over a span of seven years for well 106, Tongonan field, revealed the entry of reservoir fluid from the hotter portion of the field as the well responded to exploitation. Using a plot of discharge enthalpy versus total chloride, the deep chloride near well OP-3D which ismore »« less

An evaluation of the deep reservoir conditions of the Bacon-Manito geothermal field, Philippines using well gas chemistry

Conference D'Amore, Franco; Maniquis-Buenviaje, Marinela; Solis, Ramonito

Gas chemistry from 28 wells complement water chemistry and physical data in developing a reservoir model for the Bacon-Manito geothermal project (BMGP), Philippines. Reservoir temperature, T_HSH, and steam fraction, y, are calculated or extrapolated from the grid defined by the Fischer-Tropsch (FT) and H₂-H₂S (HSH) gas equilibria reactions. A correction is made for H₂ that is lost due to preferential partitioning into the vapor phase and the reequilibration of H₂S after steam loss.

Water use in the development and operation of geothermal power plants.

Technical Report Clark, C; Harto, C; Sullivan, J; ...

Geothermal energy is increasingly recognized for its potential to reduce carbon emissions and U.S. dependence on foreign oil. Energy and environmental analyses are critical to developing a robust set of geothermal energy technologies. This report summarizes what is currently known about the life cycle water requirements of geothermal electric power-generating systems and the water quality of geothermal waters. It is part of a larger effort to compare the life cycle impacts of large-scale geothermal electricity generation with other power generation technologies. The results of the life cycle analysis are summarized in a companion report, Life Cycle Analysis Results of Geothermalmore »« less

Geothermal noncondensable gas removal from turbine inlet steam

Conference Coury, G; Guillen, H; Cruz, D

Noncondensable gas (NCG), which is always present in geothermal steam, causes power plant inefficiencies that result in increased steam consumption and higher plant costs. In many steam fields over the world, the NCG content exceeds 5%w in the steam, a level at which steam consumption and costs increase rapidly as a function of the NCG concentration. Steam rates increase as the NCG level rises because of two factors. First, the steam jet ejectors and vacuum pumps that evacuate NCG from the turbine-condenser require more steam and electric power for their operation. Second, higher gas levels lead to a higher condensermore »« less
Subtask 2.4 – Overcoming Barriers to the Implementation of Postcombustion Carbon Capture

Other Laumb, Jason

The continued long-term use of North Dakota lignite is likely dependent on creating a business case for carbon capture, utilization, and storage (CCUS) that also addresses society’s desire to reduce carbon emissions. CCUS coupled with enhanced oil recovery (EOR) appears to be the most feasible option for utilities to sustain and grow the lignite industry. Establishing a market where lignite-powered utilities provide carbon dioxide (CO2) to oil producers depends upon a cost-effective method to capture CO2. CO2 capture technology challenges include minimization of the buildup of heat-stable salts, aerosol formation, degradation of solvents or solid sorbents, or subsequent solvent loss.more »« less
