Simple batch distillation of a binary mixture
A simple experiment such as the batch distillation of an ethanol–water binary mixture can be performed in a 3-h laboratory session using a very rudimentary apparatus consisting of a still pot and two thermocouples. Yet, the results can lead to very interesting insights to distillation and chemical engineering thermodynamics. The present article describes how one can exploit this simple laborato...
متن کاملFractional Distillation Process Utilized to Produce Light Fractional Fuel from Low Density Polyethylene (LDPE) Waste Plastic
Plastics are not easily biodegradable; and because of these characteristics they can remain under landfill and water for a very long period of time. All over the world only 6% of waste plastics are recycled and the rest of all waste plastics are dumped into landfills. An experiment was conducted in a laboratory scale batch process under Labconco’s fume hood utilizing low density polyethylene (L...
متن کاملA simple design method for multicomponent distillation columns
Multicomponent-distillation calculation methods are classified as rating or design methods. A few rating methods are widely used but none of the design methods has found general acceptance. Recently, a few design methods have been proposed using the stage-tostage calculations and starting from one of the ends of the column, but they require tedious calculations. We present here a simple design ...
متن کاملNatural Borneol Recycling from Cinnamomum camphor chvar. Borneol Oil Residue by Fractional Distillation and Recrystallization
Purpose: To establish an efficient method to recycle natural borneol from Cinnamomum camphor chvar. Borneol oil residue. Methods: The fractions and raffinate of the oil residue of Cinnamomum camphor chvar. Borneol were obtained by fractional distillation, and analyzed by gas chromatography with flame ionization detector (GC-FID) and gas chromatographymass spectrometry (GC-MS). Natural borneol w...
متن کاملApplication of artificial neural networks and genetic algorithms for crude fractional distillation process modeling
companion with genetic algorithms proved that they can accurately predict fractions quality shifts, reproducing the results of the standard laboratory analysis. Simple knowledge extraction method from neural network model built was also performed. Genetic algorithms can be successfully utilized in efficient training of large neural networks and finding their optimal structures.
