The Role of Solvent Extraction in Biodiesel Production

Bypurepath

Biodiesel is an eco-friendly alternative to diesel, produced from renewable resources like vegetable oils, animal fats, and algae. A key element in biodiesel production is solvent extraction – one of the key steps is extracting oil from feedstock, where solvent extraction plays an integral part. In this article, we explore its significance, principles used in solvent extraction as well as commonly utilized solvents during this process and its advantages.

Atmospheric Distillation Unit vs. Vacuum Distillation Unit for Crude Oil

Bypurepath

Crude oil refining is an intricate process involving the separation of hydrocarbons into various fractions based on their boiling points. Two key units that play an integral part in this process include Atmospheric Distillation Units (ADU) and Vacuum Distillation Units (VDU), although both operate similarly under different circumstances for distillation purposes and serve distinct needs.
