Oil Plant Picture
Biodiesel production processBiodiesel production process is an alternative to diesel fuel consisting of fatty acid alkLD monoesters from vegetable oils or tallow.Operation
1.Physical refining: the first hydration of oil or phosphoric acid to remove the phospholipids, glial and other substances). And then the oil preheat, dehydration, degassing into the deacidification tower, to maintain residual pressure, access to excess steam, the steam temperature, the free acid and steam co-steamed, condensed precipitation, remove free fatty acids other than the net loss, In the free acid can be reduced to very low, the pigment can be broken down, so that the color ligLDer. All kinds of waste vegetable oil in the independent research and development under the action of DYD catalyst, the use of esterification, alcoholysis at the same time the reaction process to produce crude fatty acid methLD ester.
2.Methanol pre-esterification: First, the oil hydration degumming, with a centrifuge to remove phospholipids and guLD and other hydration formed when the floc, and then dehydration of oil. The raw oil is added with excess methanol and is pre-esterified in the presence of an acidic catalyst to convert the free acid to methLD ester. The methanol water was distilled off, and after fractionation, no free acid was separated from C12-16 methLD palmitate and C18 methLD oleate.
3.Ester exchange reaction: Pre-treated fat and methanol together with a small amount of NaOH as a catalyst, at a certain temperature and atmospheric pressure transesterification reaction, which can produce methLD ester, the use of two-step reaction, through a specially designed separator continuous To remove the glycerol produced in the initial reaction, and the transesterification reaction is continued.
4.Gravity sedimentation, washing and delamination.
5.Separation of glycerol and the availability of crude methLD esters.
