“A biodiesel production block flow diagram with vegetable oil, methanol and catalyst, wash water and process heat entering reaction and purification. The process produces biodiesel product and crude glycerol; crude glycerol goes to methanol recovery, which returns methanol to the process.”
Die dahinterstehenden Entscheidungen verstehen.
Groups reaction and purification at overview level.
Separates crude glycerol from biodiesel product.
Shows methanol recovery returning material to the process.
Use this view to communicate the major material streams in a biodiesel production process.
Häufige Fragen
What reaction is used to make biodiesel?
Biodiesel is commonly made by transesterifying oils or fats with an alcohol such as methanol.
Why is glycerol shown?
Glycerol is a major co-product that must be separated and handled.
Why recover methanol?
Recovery can reduce raw-material use and shows an important recycle stream in the process.
