Abstract

Three tests were made on the kerosene sample: (a) determining hydrogen content by Nuclear Magnetic Resonance [NMR], (b) determination of viscosity by U-tube viscometer, and (c) flash point determination by Pensky-Marten closed-cup tester. Results suggest that the kerosene sample has 13.73% hydrogen content, 7.706 mm2/s kinematic viscosity at -20°C (extrapolated using Sutherland Viscosity Law), and 52-53°C flash point. These parameters characterized the kerosene sample as aviation fuel in terms of heating value, degree of saturation, pressure drop in fuel lines, pumping characteristics and safe handling. All parameters passed the standards derived from aviation literature. These parameters could Continue reading...

Summary
The experiment is meant to study the carbon dioxide absorption process in a packed tower mechanism column. The pressure performance of a packed column was determined experimentally. The calculations shoed that the pressure difference between the top and bottom part of the column is directly proportional to air flow rate; as the water flow rate increases, the pressure difference increases as well. However, at high water and air flow rates, the column flooding appears. The rate of carbon dioxide absorption was calculated. It was determined, that absorption increased carbon dioxide concentration by 80%.

Abstract

In the laboratory assignment, the experimental investigation of the distillation process is performed. The mixture of dichloromethane and trichloroethylene was separated using the glass distillation column. The influence of power input on temperatures and column flow rate was investigated. Apparently, the power input increases the efficiency of the process. The experiment had three main tasks: study of the variation of the pressure drop, application of refractometer as an express method of binary mixture composition analysis, and estimation of the column efficiency.
It has been proven that the boil-up rate is directly proportional to pressure drop. Although there is some Continue reading...
