Introduction of Automatic control continuous biodiesel machine for waste cooking oil pressing biodiesel b**0

The Biodiesel Technics we designed for your company at present is Glycerol Esterification.

This set of treatment process is a new technology as well as the latest development of our company. This process could meet the high quality standards of biodiesel with advantages such as: quick reaction, high conversion rate, get rid of the sulfuric acid as catalyst and the sulfur content can reach less than *0ppm,petty corrosion to the equipment, and no waste water, etc. This research of the process broke the history of no European standard only GB standard.

Production process has four steps: Pre-treatment, Esterification, Trans-esterification, Biodiesel distillation.

(1)Pre-treatment

Raw material oil contains a large number of moisture, impurities, before esterification reaction, it must filter crude oil, fine filtration, drying process, until obtain standard oil which has the same physical properties.

(2)Esterification

Adding the standard raw material oil, glycerin and catalysts into esterification reactor for a certain proportion and velocity, switching on the heating device to adjust the required technical parameters, reacting **3 hours under vacuum state, discharging the water produced during the reaction on time. After sample gets tested then inserting qualified material into esterification sedimentation tank. Esterification is mainly reaction between free fatty acids and glycerol generates triglycerides and water while small amounts of monoester and diester are generated.

(3)Trans-esterification

Adding the esterified material with methanol and catalysts into esterification reactor and measuring and adjusting the feed parameters of process synchronously, switching on the heating device to adjust the required technical parameters. Sample should be taken spontaneously referring different time and location, it can continuously discharge when it passes the quality test and it also can be monitored on-line.

Features of Interactive turbulence tube reactor: Interactive turbulence tube reactor: The device achieves continuously production of esterification and trans-esterification and improves the level of automation of the production process; the continuous reaction can be fully realized at low temperature and pressure, high efficiency, easy installation, easy operation, low energy consumption, The reaction of control can be achieved online, and many other advantages.

(4) Biodiesel Distillation

Biodiesel distillation device for a multivariate adaptive bypass reduced pressure distillation device, in the condition of vacuum distillation of crude methyl/rectification. Process for cold material with top of gas phase composition to heating of heat transfer firstly, heat transfer materials through the heater heating again after the temperature meet the process requirements and then into the reactor to distillation or rectification, (rectification control reflux ratio),the tower of the gas phase material after heat condensation, the principal component into the receiving tank, light component via to overhead condenser under certain technological conditions entered into a receiving tank after cooling, the components of the effusion dish into a receiving tank, the bottom black feet by the pumps. Its advantage is: distillation, rectification, separation system as a whole, the residence time of biodiesel in equipment was decreased, and ensures that the color of the biodiesel, cold finished materials with heat transfer and heat into the distillation tower, give full consideration to the secondary heat energy utilization, greatly saves the cost of production; Deodorization and primary production in the tower separation, a combination of stench gas after the AO pool microorganisms dissolution of sewage treatment standards, not only reduce the heat loss, but also save the equipment investment, widen the elasticity of operation, also has brought great convenience to production operation.
