Biodiesel Production Plant

Akfen Engineering is a company with successful partnerships with its customers in terms of the plant establishment, installation, personnel training and commissioning of the plant in Central Asia, Europe and Africa in the field of biodiesel production plant.

Biodiesel is a product that is released as a result of the reaction of vegetable oils obtained from oilseedplants such as canola, sunflower, soy and safflower with a short chain alcohol (methanol-ethanol) accompanied by a catalyst and used as fuel. Biodiesel can be produced from any herbal or waste oil. The process of converting these oils into biodiesel is called transesterification.

Biodiesel can be used in vehicles as fuel or used by combining with regular diesel.

B5: 5% Biodiesel + 95% Diesel Fuel
B20: 20% Biodiesel + 80% Diesel Fuel
B50: 50% Biodiesel + 50% Diesel Fuel
B100: 100% Biodiesel

Biodiesel can be used without any modification on the engine. The benefit to the engine is enable 20% to 25% more kilometers than normal diesel.

It extends engine life with its lubricating feature on the engine.

Biodiesel, an alternative diesel fuel, is compatible with the environment and is a fuel that is biodegradable in a short time.

Below mentioned elements are prevented with the use of herbal and grease waste oils in the production of biodiesel;

• Greenhouse gas effect such as carbon dioxide
• Discharge of carcinogenic chlorinated organic substances from the exhaust to the atmosphere
• Unburned hydrocarbon emission
• Emission of ozone-forming pollutants
• 75% more pollutant removal from exhaust than diesel fuel
• More pollution of water resources
• Discharge of sulfur dioxide from the exhaust, unlike diesel fuel

How the Biodiesel Plant Works 

Biodiesel can be produced by 3 different methods. These methods are as follows.

• Transesterification of oil by base catalysis

• Transesterification of oil by direct acid catalysis

• Conversion of oil to biodiesel by converting it to elaeostearic.

As Akfen Engineering, we use base catalysis and oil transesterification, which is the most economical method in biodiesel production.

The oil is passed through a pre-filter and taken into the reactor. Biodiesel is produced by mixing the catalyst materials with heat treatment in the reactor.

The detailed process is as follows:

1. Alcohol and Catalyst Mixtures

The catalyst substance dissolves in alcohol using a chromium mixer and starts the reaction by added to the oil. 

2. Reaction

The oil taken into the reactor is heated between 70 and 80 C to make it suitable for reaction and the previously prepared catalyst mixture is added to the oil.

3. Allocation

Biodiesel and glycerin products are obtained after the oil catalyst mixture. Glycerin is separated from biodiesel by using density difference.

4. Washing Process

After the separation process, the washing process is carried out with hot water to completely separate the remainder catalyst and glycerin left in the biodiesel.

5. Drying

In order to completely remove the water and moisture in the biodiesel, the substances are distilled by vacuum pumping under high temperature.

6. Storage

After the procedure, biodiesel and glycerin obtained with the help of the pump are ready for sale and sent to stock tanks to load on trucks
