Embodiment 1

[0038] like figure 1 As shown, the present embodiment provides a kind of equipment for removing benzene and rich oil, including: a superheated riser, a desuperheater, and a debenzene tower; wherein, the superheated riser has a first pipeline and a second pipeline, and the first pipeline has Raw coal gas is passed through, saturated steam is passed through the second pipeline, the second pipeline wraps the first pipeline, and the saturated steam is heated to the superheated steam of the first temperature by using the waste heat of the raw gas in the first pipeline; the desuperheater is used to convert the first The superheated steam at the second temperature is reduced to the superheated steam at the second temperature; the debenzene tower is connected with the second pipeline steam path, and is used to debenzene the rich oil under the action of the superheated steam at the second temperature.

[0039] It can be seen from this that the equipment provided in this embodiment reli...

Embodiment 2

[0051] This embodiment provides a method for removing benzene and enriching oil. The method provided in this embodiment can be used to use the equipment in Example 1. Specifically, as figure 2 As shown, the method provided in this embodiment includes the following steps:

[0052] S1. Using the waste heat of raw coal gas to heat the saturated steam to the superheated steam of the first temperature.

[0053] Specifically, in this step, the subject of execution is the superheated riser in the equipment provided in Example 1, and the superheated riser has a first pipeline and a second pipeline, wherein raw gas is passed through the first pipeline, Saturated steam passes through the second pipeline, and the second pipeline wraps the first pipeline, so that the superheated riser uses the waste heat of raw coal gas in the first pipeline to heat the saturated steam to the superheated steam of the first temperature.

Abstract

The invention provides rich oil debenzolizing equipment and method, belongs to the technical field of coking, and can solve the problem of air pollution caused by combustion in the conventional tubular furnace. The rich oil debenzolizing equipment comprises an overheating riser, a desuperheater and a debenzolizing tower, wherein the overheating riser comprises a first pipe and a second pipe; the first pipe is inflated with raw coke oven gas; the second pipe is inflated with saturated steam; the second pipe enwraps the first pipe; afterheat of the raw coke oven gas in the first pipe is utilizedfor heating the saturated steam into overheated steam with a first temperature; the desuperheater is used for cooling the overheated steam with the first temperature into overheated steam with a second temperature; the debenzolizing tower is communicated with a gas path of the second pipe and is used for debenzolizing rich oil under the action of the overheated steam with the second temperature.

Description

technical field [0001] The invention belongs to the technical field of coking, and in particular relates to equipment and a method for removing benzene-rich oil. Background technique [0002] The crude benzene distillation process refers to the debenzene removal of rich oil. At present, tube furnaces are widely used in crude benzene distillation process. [0003] However, the inventors have found that the tube furnace mainly heats the rich oil by burning coke oven gas, and the exhaust gas produced by the coke oven gas combustion contains a large amount of sulfur dioxide and nitrogen oxides, which cause great damage to the air. pollution. Moreover, in the prior art, because the total amount of exhaust gas is too small, the scale of the exhaust gas treatment device is not large, and the crude benzene distillation tube furnace is located in the chemical production area, surrounded by many Class A buildings and flammable and explosive equipment, resulting in It is extremely d...
