Existing theories describe corrosive wear in crosshead diesel engines in terms of acid condensation, when the temperature in the combustion space drops below the dew point. Here a theory is proposed which stresses the role of alkaline cylinder lubricants in protecting the metal surface. Calculated liner wear rates as a function of fuel sulphur content, feed rate and alkalinity of the oil, and a...

In this paper, an advanced analysis of a novel hybrid compression-absorption refrigeration system (HCARS) for natural gas dew point control unit in a gas refinery is presented. This unit separates the heavy hydrocarbon molecules in the natural gas, which is traditionally carried out by natural gas cooling in a compression refrigeration cycle (CRS). The power input required for the refrigeration...

Indirect evaporative cooling can meaningfully improve the natural environment. It involves low operating costs for air systems. The dew point indirect cooler (DP-IEC) is energy-efficient, ecological, and economical. current study reports on an experimental analysis of a DP-IEC working under wide range conditions integrated with solar panel system. electricity consumption be met by utilizing ren...

In this study, an innovative indirect evaporative cooler is presented and experimentally analysed. A prototype was assembled for the experimental investigation of system tested in laboratory environment under conditions constant air flow rate 350 m3/h, circulating water temperatures 15°C 20°C, inlet 25°C 30°C lastly humidity 9g/kg 13g/kg, respectively. Based on data obtained during experiments,...
