Problems solved by technology

The domestic industrial production of transesterification is mainly based on single-stage gap, and there are many shortcomings such as incomplete transesterification and poor quality of crude glycerin.
When the esterified oil obtained from glycerol esterification of waste diesel oil is subjected to subsequent transesterification treatment, there is usually the problem of incomplete transesterification with a single-stage gap. In addition, the quality of crude glycerin is poor, and the mass fraction of glycerin is only about 60%. The consumption of sodium hydroxide and / or potassium hydroxide is as high as 0.75%-1% of the quality of the esterified oil, and it is currently impossible to process the esterified oil continuously and efficiently

Abstract

The invention relates to a system for treating esterified oil. The system comprises an esterification oil tank, a methanol alkali liquor tank, a deacidification reaction kettle, a first ester exchangereaction tower, a first separation tank and a first methanol alkali liquor tank; a discharge port of the esterification oil tank is connected with a feed port of the deacidification reaction kettle;a discharge port of the deacidification reaction kettle is communicated with a feed port of the first ester exchange reaction tower, and a discharge port of the methanol alkali liquor tank is communicated with a feed port of the first ester exchange reaction tower; and a discharge port of the first ester exchange reaction tower is communicated with a feed port of the first separation tank. The system can be used for continuously and efficiently obtaining the layered liquid with high glycerol content from the esterified oil by using a small amount of methanol alkali liquor.

Description

technical field [0001] The invention relates to the new field of oleochemical biodiesel, in particular to a system for processing esterified oil. Background technique [0002] The preparation of biodiesel from vegetable oils has attracted people's attention, because its combustibility is not inferior to that of petrochemical diesel, and it can be directly used in diesel engines and other petrochemical diesel fields. It is generally believed that biodiesel will be a substitute for petrochemical diesel in the future. Biodiesel has the following advantages: non-toxic and biodegradable, high cetane number, less sulfide carbon monoxide emissions, and the carbon it emits comes from the atmosphere. Compared with petrochemical diesel, it can greatly reduce carbon dioxide emissions. [0003] At present, due to the shortage of vegetable oils in China, the production of biodiesel mainly uses waste oils and fats from high-acid value kitchens and hogwash oil as raw materials. The produc...
