Biodiesel Production Process Steps

Biodiesel pretreatment esterification and ester exchange station

Step 1: Pre-treatment

Pre-treatment includes degumming and/or bleaching, both of which remove certain non-volatile impurities through filtration. Raw materials containing phospholipids/gums undergo a degumming process, in which phosphoric acid is mixed with the oil to form gums. These gums are then separated in a centrifuge.

In the bleaching process, bleaching earth is applied to crude oil to minimize the residual pigments (such as carotene and chlorophyll), heavy metals, and phosphorus content after degumming.

Step 2: Esterification and Ester Exchange

The oil is fed into a stirred reactor and maintained at the required oil temperature. A dilute alkaline solution (10% w/w) is added to the reactor to maintain the pH between 5.5 and 6. Water (2%) is added to the reactor to maintain the moisture content required for enzyme activation.

Enzymes are added at a concentration of 0.25% to 0.3%. Typically, the reaction requires methanol based on 20% of the initial oil content. The required methanol flow rate is maintained for 24 hours.

Step 3: Flash

Flash distillation is the process of removing methanol and water from crude biodiesel. Crude biodiesel from the esterification reactor is transported to the reaction tank. The mixture is heated and fed into the flash tank.

Methanol and water vapor in the flash tank condense in the flash tank steam condenser. The methanol-water condensate is collected in the methanol recovery tower feed tank and sent to the methanol tower. The methanol-free biodiesel and glycerol phase enter the centrifugal section.

Step 4: Glycerol Separation

This process separates glycerol from crude biodiesel. The material in the feed tank is sent to the horizontal screw centrifuge. The horizontal screw centrifuge separates crude biodiesel (FAME) and crude glycerol based on density differences.

Crude glycerol is sent to the centrifuge for further purification. Crude biodiesel from the horizontal screw centrifuge and centrifuge is collected in the feed tank. Crude biodiesel is transported to the neutralization section.

Step 5: Neutralization

The purpose of this step is to remove unreacted free fatty acids from crude biodiesel (FAME). FAME is heated to 80–85°C, and a chemically metered 10% NaOH solution plus an additional 10% solution is added to the crude biodiesel phase.

Neutralization requires a certain residence time. After the reaction, the mixture is sent to a centrifuge to separate the soap residue and neutralized biodiesel. The soap residue is then transferred to a storage tank. The FAME is sent to a washing centrifuge to remove residual soap.

Step 6: Washing

Water washing or citric acid washing can reduce residual soap in neutralized FAME by up to 600 ppm. Hot water is mixed with the oil and passed through a centrifuge.

The washed biodiesel is transferred to the flash section. The washed biodiesel contains up to 1% moisture and is sent to the flash section to remove moisture present in the biodiesel.

Step 7: Drying

Moisture removal in the flash unit occurs under vacuum and temperature conditions. The biodiesel is pumped through a heat exchanger to the flash evaporator.

The vacuum is maintained by a vacuum pump or ejector, which have their own cooling systems and tanks for the working fluid (water). The dried biodiesel is further transported to the distillation section.

Step 8: Esterification and Ester Exchange

The washed FAME is fed into the molecular distillation tower. Distillation is conducted under high vacuum. The FAME mixture is heated to its boiling point using a thermal fluid heating system. FAME condenses in the distillate tank, while impurities condense in the residue tank.

The methanol recovery section consists of a methanol distillation tower, which is mainly used to separate water and methanol during the biodiesel production process to recycle and obtain high-purity methanol.

Huatai Group Biodiesel Production Line

The free fatty acid in the waste oil was esterified with methanol to convert into fatty acid methyl ester by heat preservation, sedimentation and water removal of the waste oil raw material; Under the condition of alkaline catalyst, the fatty acid glyceride in waste oil was transesterified with methanol to convertinto fatty acid methyl ester (biodiesel). Distillation and purification: under the condition of high vacuum, the crude methyl ester is pumped into the three-stage distillation tower of biodiesel for vacuum distillation. The crude biodiesel is divided into: light biodiesel, bio diesel, bio-heavy oil and vegetable asphalt through the three-stage fractionation and desulfurization section to meet the needs of different fields. Finally, an asphalt tower is set separately to improve the product yield and the quality of bio asphalt. Biodiesel products meet EU standards.
