DEWAXING DEVICE AND METHOD OF DEWAXING USING THE DEWAXING DEVICE

摘要

A dewaxing device and a method of dewaxing using the dewaxing device are shown. The dewaxing device includes a dewaxing system including a rinsing device and a storage device, and a recycling system connected with the storage device. The storage device includes a first solvent trough and a second solvent trough of which each is connected with the rinsing device and is equipped with a heating equipment. When the first solvent trough is connected with the rinsing device, the second solvent trough is disconnected with the rinsing device; when the second solvent trough is connected with the rinsing device, the first solvent trough is disconnected with the rinsing device. So, the dewaxing device can provide two dewaxing processes and effectively reduce recycling frequency because the recycling process is done after soluble wax quantity of bromopropane solvent reaches the maximum value 16%. The production cost is accordingly reduced.
