“…Diesel engines operate with hot compressible air intake and ignition occurs due to high temperature and pressure releasing notable NOx emissions. The focus has shifted to using other clean fuel sources to comply with environmental regulations [41][42][43]. Accordingly, using LPG for dual-fuel combustion in diesel engines achieves this goal.…”

Liquefied petroleum gas (LPG) is a mixture of hydrocarbons essentially propane and butane. It has recently emerged as a sustainable and alternative fuel source to other conventional fossil fuels in several sectors such as residential, industrial, commercial and transportation. The environmental impact is seen as a positive influence as it reduces black carbon emissions by releasing less greenhouse gases as it undergoes combustion. In this study, a general overview about LPG was offered and the data required for simulating a flowsheet for LPG production was obtained from an LPG plant. Mass balance and energy balance were calculated manually and compared with those of the simulation performed by ASPEN HYSYS 12.0 using Peng-Robinson fluid package. A hazard and operability study for the equipment was carried out as well as their spacing to emphasize their importance on how they shape the safe feasibility of plant construction. It was found that 2209 kg/h of feed gas was mainly converted to 836.90 kg/h of sales gas and 1322 kg/h of LPG. By comparing manual calculations with HYSYS results, the duty for heat exchanger 2 was 55361.17 kJ/h, with error percentage of 3.90%. The sales gas temperature was 318.53 K with 1.42% deviation. Debutanizer condenser and reboiler duties were 892640.20 kJ/h and 746416.30 kJ/h, with deviations of 4.25% and 3.49% respectively. The hazard and operability studies and spacing showed that all the equipment must be positioned at safe distances apart from each other and they require the installation of alarms, sensors, and controllers to ensure a proper and safe production process.

“…The experimental evaluation was implemented based on the computed values of productivity (P r ), temperature polarization coefficient (τ), and heat-transfer coefficient (h f ). It is difficult to measure the feed temperature (T fm ) and concentration (C fm ) experimentally at the membrane surface [9,29]. Thus, a mathematical model was introduced beneath for the AGMD module alongside the experimental data to determine each of T fm , C fm , h f , and τ.…”

This work aimed to investigate temperature polarization (TP) and concentration polarization (CP), which affect solar-powered air-gap membrane distillation (SP-AGMD) system performance under various operating conditions. A mathematical model for the SP-AGMD system using the experimental results was performed to calculate the temperature polarization coefficient (τ), interface temperature (Tfm), and interface concentration (Cfm) at various salt concentrations (Cf), feed temperatures (Tf), and flow rates (Mf). The system of SP-AGMD was simulated using the TRNSYS program. An evacuated tube collector (ETC) with a 2.5 m2 surface area was utilized for solar water heating. Electrical powering of cooler and circulation water pumps in the SP-AGMD system was provided using a photovoltaic system. Data were subjected to one-way analysis of variance (ANOVA) and Spearman’s correlation analysis to test the significant impact of operating conditions and polarization phenomena at p < 0.05. Statistical analysis showed that Mf induced a highly significant difference in the productivity (Pr) and heat-transfer (hf) coefficients (p < 0.001) and a significant difference in τ (p < 0.05). Great F-ratios showed that Mf is the most influential parameter. Pr was enhanced by 99% and 146%, with increasing Tf (60 °C) and Mf (12 L/h), respectively, at a stable salt concentration (Cf) of 0.5% and a cooling temperature (Tc) of 20 °C. Also, the temperature increased to 85 °C when solar radiation reached 1002 W/m2 during summer. The inlet heat temperature of AGMD increased to 73 °C, and the Pr reached 1.62 kg/(m2·h).
