Thermoecological cost of electricity production in the natural gas pressure reduction process

Thermo-ecological assessment of CCHP (combined cold-heat-and-power) plant supported with renewable energy

“…A corresponding detailed formulation can be found in Refs. [31,37,39], and only main equations are summarized below.…”

“…It can be demonstrated [37,39], that the exergy cost of the products of all components can be obtained by applying the following equation:…”

“…Comparison of different refrigeration systems should be based on exergy efficiency and exergy losses [21]. However, as the direct exergy analysis fails to show the exergetic results of interactions between system components, complex energy systems, or in general any production systems, should additionally be analysed with the tools offered by the TEA (thermo-economic analysis) [22e25, 35,36,39]. The potential of this approach in the case of a multi-purpose industrial park is efficiently demonstrated e.g.…”

Optimizing natural gas reciprocating expansion engines for Town Border pressure reduction stations based on AGA8 equation of state

“…Bisio (Bisio, 1995) is one of the researchers that proposed systems to use this wasted energy, including a mechanical system to compress air. Another method for using natural gas pressure energy is expansion turbines (turbo expanders) that generate electricity (Greeff et al, 2004;Farzaneh-Gord and Deymi-Dashtebayaz, 2008;FarzanehGord and Maghrebi, 2009;Kostowski et al, 2014;Kostowski and Us on, 2013). In one study, Greeff et al (Greeff et al, 2004) have investigated merging of expander turbines into different high-pressure exothermic chemical-synthesis processes.…”

Sustainable development of energy, water and environment systems

“…As to the other fuel types, the geothermal power plant Velika Ciglena is taken as a case to assess comparatively a basic and a dual-pressure Organic Rankine Cycle (Guzovic et al [10]), the thermoecological cost assigned to the electricity production in the process of natural gas transmission at pressure reduction stations is determined (Kostowski et al [11]), as well as an overview is provided of fuel production cost for two types of synthetic fuels e methanol and methane, and comparable costs of biodiesel, bioethanol and biogas (Ridjan et al [12]). …”
