Why distillation metters?
Fuels from the past derived primarily from petroleum. Due to the challenges of non-renewable fossil fuel, emissions control, biofuels emerge to address a source of sustainable energy with better emissions. The study of their distillation curves has still remained a critical test for the process and product quality control; from refining, blending, process optimization, up to final product regulatory compliance.
Boiling point (BP) provides information about fuel composition, properties, and characteristics when in storage or usage and it also serves as an indicator of fuel volatility, which is directly related to the performance and pollutant emissions of the engines. As an example, in gasoline-fueled engines, if volatility is low, difficulty in starting up of may happen as gasoline does not exist in the gas phase, while in diesel engines, a low volatile diesel will lead to soot formation, loss of power and increased fuel consumption due to poor combustion. In contrast, having high volatility of gasoline and diesel may end up to a “vapor lock” as fuel tends to vaporize in the tank or in the flow lines, cascading to engine damages.
Process control in refining
Refining starts with the separation process, generally by atmospheric distillation, vacuum distillation, and gas processing. The role of the distillation test at this stage is very important since it gives the boiling point data to optimize the process control in separating the crude oil components from light to heavy distillates.
More profit in process/cutpoint optimization
Distillation curves of petroleum products are typically plotted as True Boiling Points (TBP) temperature versus relative yield percent. Thanks to the technology advancement that permits process control/ cut point optimization to shift boiling points. Through this approach refinery can yield more volume of higher selling value products through the installation of most precise and accurate online and lab analyzers.
