Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] Such as figure 1 As shown, the embodiment of the present invention provides a solvent deoiling device, which changes the traditional sweating room or oven room into a tubular deoiling tower, reducing the footprint of a unit deoiling device.

[0029] The solvent deoiling device in the embodiment of the present invention includes a deoiling raw material tank 10, a solvent tank 11, a deoiling tower 12, a solvent and wax oil collection tank 15, a second buffer tank 16, a second vacuum pump 17, and a safety gas unit 18 .

[0030] The deoiling raw material tank 10 is used to accommodate the raw material to be deoiled, and it can be provided with a heating unit, such as an electric heating unit or a heat transfer oil hea...

Abstract

The invention relates to a solvent deoiling device, which comprises a deoiling raw material tank, a solvent tank, a deoiling tower and a solvent and under-wax oil collecting tank, the deoiling raw material tank and the solvent tank are connected with an inlet of the deoiling tower, a filter screen is arranged at the bottom of the deoiling tower, and an outlet of the deoiling tower is connected to the solvent and under-wax oil collecting tank, and a heating and cooling jacket is arranged on the outer wall of the deoiling tower. The device is simple to operate, low in cost, wide in adaptability and high in solvent recovery rate and deoiling efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a solvent deoiling device and method. Background technique [0002] In the process of petroleum refining, high-wax distillate oil and residual oil are obtained after separating light fuel oil components such as steam, coal, and diesel oil. Among them, the high-wax distillate oil can be separated from paraffin and base oil by solvent method or freezing method, so that the obtained paraffin also contains 1%-5% "oil". The inclusion of these residual oils in paraffin will reduce the melting point of paraffin and make Paraffin softens and gives the wax an oily smell. This brings a lot of negative properties to the widely used paraffin wax, and even affects its use. [0003] The existing solvent deoiling device has high cost, bulky device and mediocre deoiling effect. The classic deoiling process that has been around for many years is known in the industry as "...
