Problems solved by technology

The yield of low-temperature tar is about 8% of coke. my country's shaft furnace coking coke has reached more than 10 million tons, and the annual output of low-temperature tar can reach 1 million tons. So far, low-temperature tar has been used as fuel oil, and each of the low-temperature tar Distillate products are not fully utilized, especially the homologue content of phenol is 10 times higher than that of high-temperature tar phenol, up to 19.56%.

Embodiment Construction

[0008] The 50,000t / a tar processing and renovation project of Hengli Chemical Plant in Haicheng City, Liaoning Province. The plant originally had a set of 50,000t / a petroleum refining equipment, and a set of evaporator equipment was added in front of the tube furnace. Using this set of atmospheric pressure equipment, the acid , Alkali washing equipment;

[0009] 1. Using low temperature tar as raw material;

[0010] 2. The specific processing steps are as follows:

[0011] Let the low-temperature tar stand in the storage tank to remove part of the water, and then transfer the low-temperature tar from which part of the water has been removed to 120-130°C through a heat exchanger, then pump it into the evaporation tower, and distill light oil gas from the top of the tower The temperature is controlled at 105-110°C. After condensation and cooling, the oil and water are separated, and the light oil enters the intermediate storage tank, and the sewage is sent to the sewage treatme...

Abstract

A process for processing the low-temp tar oil to prepare light oil, dephenolized oil, coarse phenol and fuel oil includes such steps as laying aside to dewater it partly, heating to 120-130 deg.C by heat exchanger, pumping it in evaporation tower, fractionating to obtain light oil gas at 105-110 deg.C, and oil-water by condensing to obtain light oil and sewage.

Description

technical field [0001] The invention relates to the technical field of tar processing, in particular to processing and producing light oil, dephenolized phenol oil, crude phenol and fuel oil products by using low-temperature tar as a raw material. Background technique [0002] Low-temperature tar is a by-product produced in the coking process of the shaft furnace. It is a viscous flowable object such as tar, water, coke powder, coal powder, and carbon black. The yield of low-temperature tar is about 8% of coke. my country's shaft furnace coking coke has reached more than 10 million tons, and the annual output of low-temperature tar can reach 1 million tons. So far, low-temperature tar has been used as fuel oil, and each of the low-temperature tar Distillate products are not fully utilized, especially the homologue content of phenol is 10 times higher than that of high-temperature tar phenol, up to 19.56%. Contents of the invention [0003] The purpose of the present invent...
