What does distillation curve indicates explain?
1 The distillation curve is a graphical depiction of the boiling temperature of a fluid mixture plotted against the volume fraction distilled. The temperature at each of these cuts or regions provides an idea of the volatility of each cut.
What is IBP and FBP?
Initial Boiling Point (IBP) The temperature at which the first drop of distillate appears after commencement of distillation in the standard ASTM laboratory apparatus. Final Boiling Point (FBP) The maximum temperature observed on the distillation thermometer when a standard ASTM distillation is carried out.
What is D86 distillation?
ASTM D86 is the standard test method used to experimentally measure the batch distillation curve of a petroleum-derived fuel at atmospheric pressure [4]. The thermometer is positioned to measure the temperature of the fuel vapor as it rises and exits the neck of the distillation flask.
What is the use of ASTM distillation?
ASTM Distillation refers to a diverse group of different ASTM International standards. These different ASTM standards all use the distillation (volatility) characteristics of the substrate in determining the adherence (or not) of the substrate to the standard.
What is ASTM D2892?
True boiling point distillation distills crude oil from the initial boiling point up to 370-400 °C. D2892 is the ASTM test number. It is most commonly used to test crude oil and crude oil blends. The distillation typically takes place in 3 pressure sequences, atmospheric, 100 mmHg vacuum, and 10 mmHg vacuum.
What is ASTM D93?
ASTM D93 stands for standard test methods for Flash Point by Pensky-Martens Closed Cup Tester. The ASTM D93 standard test method can be devided into three procedures: Procedure A covers destillated fuels such as diesel, biodiesel blends, kerosine, heating oil and turbine fuels.
What is meant by pour point?
Pour point is defined as the lowest temperature at which the test fluid can be poured under the prescribed test conditions. It is one of the properties that determine the low temperature fluidity of a lubricating oil.
