Manufacturing method from Waste Cooking Oil

By- Asheesh Padiyar & Manas Likhit R.V College of Engineering Dept of Chemical Engineering 2012-2016

As crude oil price reach a new high, the need for developing alternative fuels has become acute

Alternate fuel should be economically attractive in order to compete with the currently available fossil fuels

Fossil fuels over ??

Alternative ??

Electric automobiles

Solar powered automobiles

Fuel cell powered automobiles

Procedure

Step 1- Free fatty acid test (FFA)

If FFA>4% Double Stage process

If FFA <4%Single Stage process

The end point

Step 2 – The conversion

Heating the sample up to 60º C with constant stirring . Addition of methoxide

catalyst and stirred

Heating The catalyst

Step 3 – The separation

Transfer of the mixture into a separation funnel.

Allowing it to separate under gravity.

The separating funnel

The separated phases

Step 4- Washing

Glycerol separated.

Biodiesel heated to 60˚ C and washed with fine spray of water.

Washing

Repeated washed till the pH of the water after washing reaches the initial value.

The final product

Viscosity test:

Viscometer dipped in water preheated to 40˚ C

Viscosity is found out by finding time taken by liquid to travel between two marked points

Tests:

The viscometer

Copper strip corrosion test:

Biodiesel heated to 60˚C and copper strip placed in it

Heating done for 3 hours

Copper strip removed after

3 hours

Copper strip corrosion test

Copper strip after test

Flash point test:

Biodiesel heated to 100˚C and checked for flash point at different temperatures using ignition source.

Advantages ??

Low carbon emission

Renewability

Source material

Cost

Disadvantages ??

Low energy output

High cost of refining

Massive quantity of water needed
