New technology patent on making biodiesel from acid oil

New technology patent on making biodiesel from acid oil

1.Brief Introduction of Kingdo Biodiesel Making Equipment

To adapt to the market change at home and abroad, and the significant features of scale merits regarded as the development trend in oil industry, Henan Hi-tech Kingdo Industrial Co., Ltd, has sucessfully developed the biodiesel making project by taking unfit human consumption and waste animal and vegetables oil as raw meterials, which extends the productivity and reduces the cost. It is the green health concept that guiding the enterprise brand benefit and temporizing to the requirement of market development. We have our machine manufactured in our advanced workshop and can help the client install and comissioning oversea.

2.Construction Scale of Biodiesl plant

Raw material of biodiesel plant receiving: 10~ 500t/d

Raw material storage scale of biodiesel plant :~20000t

Pre-treatment workshop of biodiesel plant: 10~500t /d

Synthetic refining workshop of biodiesel plant: 10~500t /d

3.Main Materials of Biodiesel plant

• waste oils, waste vebetable oil: soybean oil, rapeseed oil, sunflower oil, palm oil
• animal oil
• acidulated oils
• swill cooked dirty oil

1.Engine is starting at low temperature(-10C).

2.It not belongs to dangerous cargo, so it’s easy to transport.

3.There is less sulfur and aromatic alkyl in biodiesel, so it's less harmful to human and environment.

4.As a kind of renewable energy sources, the biodiesel will not finised.

5.The supply of biodiesel is not controlled by OPEC, it’s benefit to the stability of international petroleum market.

5. Main Biodiesel Making Equipment

(1) Physical degumming: first of all, using oil hydration or phosphoric acid-etching method, remove the phospholipids and colloid and other substances, and then preheating, dehydration the oil.

(2) Methanol esterification: adding excess methanol into the raw oil material, with the acid catalyst, conduct pre-esterification, changing free acid into methyl ester.

(3) Continuous ester exchange: the pre-esterification oil together with methyl alcohol, adding little NaOH as catalyst, under a certain temperature and atmospheric pressure, conduct ester exchange, then get methyl ester.

Using two-step reaction, through a specially designed separator continuously eliminate the glycerin engendered in the reaction, make the ester exchange continuously.

(4) Gravity precipitation, water washing and stratification.

(5) Glycerol separated from crude methyl ester.

(6) Biodiesel refined machine.

The whole process is closed-circuit circulation, all raw material comprehensive utilization, cleaner production. Roughly described as follows:

Raw material pretreatment (dehydration, deodorization, purification )-----the reaction kettle (methyl ester+ alcohol catalyst + 70°C) -----stirring reaction N hours----precipitation separation line of mixed alcohol----methyl distillation----recovery of alcohol----methyl ester distillation----finished product.
