What is the use of waste engine oil recycling and how to deal with waste engine oil?
Afterwaste machineOil recoveryIt can be used for refined diesel. Refining waste engine oil can not only solve the problem of recycling tens of millions of tons of waste engine oil every year in China, but also is a kind of recycling of waste engine oil. For the recovery of waste engine oil, first add the preservative into the water and stir, then add the release agent core masterbatch into the water and stir, soak for one hour and stir evenly, then add the waste engine oil and flavor pigment into the water and stir, add the instant acid and alkali resistant transparent thickening powder and wire drawing powder into the water and stir for about half an hour. So, how is diesel extracted from waste oil?
Currently, regeneration andWaste oil recyclingThere are two ways:
1. The waste oil (waste lubricating oil) is pumped into the reaction kettle of the waste oil secondary refiner, and the base oil, gasoline, diesel oil, residual oil and other products are extracted after distillation and purification, and the non-standard diesel oil is extracted after the impurities in the oil are removed by acid washing, alkali washing and filtration.
2. The waste oil is first pumped into the reaction kettle of the waste oil secondary refiner, and the oil and gas are cracked into oil and gas through the heat transfer oil coiled at the bottom of the reaction kettle and inside the reaction kettle. Oil and gas enter the multi-stage catalytic tower, in which multi-layer packing is placed, and catalysts with different functions are placed in the packing. Degumming, dewaxing and decolorizing catalysts are typically used.
The difference between the two methods is: The former method is to crack the used engine oil, condense it into oil, and then filter it with acid and alkali to decolor to obtain diesel oil; the other method is to crack the used engine oil into oil and gas and enter the multi-stage catalytic tower, which has different functions The catalyst is filtered and condensed into diesel.
