Preparation of the antifreeze concentrate
Thread Content
As is well known, antifreeze agents have a high freezing point; when stored outdoors in barrels during winter, they will solidify. They need to be warmed up before being pumped into the mother liquor tank. As for how various units go about this warming process and what methods are used to transfer the substance into the mother liquor tank, given that the mixture becomes quite viscous after being treated, how can the mother liquor be prepared in a clean and efficient manner?
Our unit has built a simple heating chamber; the barrels are placed inside it, where heaters provide heat. Then, a cart designed for lifting barrels is used to lift them and pour their contents into a rectangular trough. A small pump is used to transfer the contents to the mother liquor tank, and a Venturi tube is employed to transfer the antifreeze from the mother liquor tank into the finished product tank. A diesel pump is used to circulate the liquid in the finished product tank, thereby removing the mother liquor.
- Our unit first heats the mother liquor (crude oil) to 80 degrees, then adds the pour point depressant (particles), and stirs for 12 hours
