Abstract There are many pieces of high-temperature and high-pressure system equipment in nuclear power plants, such as deaerators, feedwater heaters, steam-water separation reheaters, etc. The media parameters these systems high the working conditions complex. It is necessary to solve above problems by adopting multi-channel averaging, increasing slope condensing line, separating sampling ports...

Abstract Hydrothermal Carbonization (HTC) refers to the conversion of biogenic wastes into char-like solids with promising perspectives for application, but a process water (PW) results which is difficult dispose untreated. Thus, biorefinery approach including one or two recirculation steps additional objective improving physico-chemical characteristics solid was performed in this study. During...

Geothermal Aided Power Generation (GAPG) technology is a geothermal hybrid power system that energy has been integrated into the fossil fired plant to preheat feedwater, and displace extraction steam of plant. In such system, heat exchange process between geo-fluid occurs in between. When exchanger quench lower temperature for transfer purpose, silica scaling would occur system. The performance...

Modeling mass transport of ions across the polyamide active layer a reverse osmosis (RO) membrane requires comprehensive understanding structure and chemistry. For instance, charge ionization thus salt greatly depend on feedwater pH composition, but these relations are not yet well understood. To address this gap in understanding, one dimensional model is developed that couples all using extend...

The oxy-combustion technology is ready for demonstration [1]. However, the energy penalty and investment cost related to CO2 capture are still too high to implement this technology in the power industry. The thermal efficiency penalty is currently around 10% points, and as discussed in [2] it is commonly expected to be reduced to below 6% points in the near future. Improvements on the sub-units...
