Problems solved by technology

[0002] At present, coal tar is taking the advantage of low price to replace mixed crude oil in steam injection boilers, but its effect is average, and the main problems are as follows: First, the ash content of coal tar is relatively large, and the number of soot blowing in boilers is relatively large
Third, due to the high viscosity, coal tar can only be used above 60°C, which limits its use and increases the cost

Embodiment 1

[0016] The main raw material coal tar in this invention is medium-temperature fuel oil, which has low viscosity, high calorific value, low ash content, low water content, and no corrosion to equipment. When blending, the raw materials need to pass through 10 mesh, 20 mesh, 40 mesh, and 60 mesh. , 80-mesh multi-stage selection filter, which can remove the colloid, asphaltene and ash impurities, and solve the problem of clogging the burner during use. When mixing, put it into the oil-water separation tank and heat it to above 70°C. The separation of oil and water can be accelerated in the raw materials. The dehydrated raw oil is then transported to the storage tank for process deployment. First, add 10-30% of heavy oil, 0.5-10% of heavy oil, combustion aid (heavy oil) and thousand 1 / 10 to 5 / 10000 concealer industrial essence, and then the added liquid and raw materials are stirred evenly, and after mixing, they are sent through an 80-mesh filter for filtration, and then the produ...

Embodiment 2

[0018] The appropriate amount of combustion enhancer and industrial flavor added during the preparation of the present invention can be used as a decoking agent and a dispersant to improve the fluidity of oil products and reduce viscosity during use, increase calorific value, reduce pollution, and solve the problem of leakage during combustion. Benzene, naphthalene, and methylbenzene in smoke, ash, and high-temperature tar are highly volatile, and the peculiar smell is a big problem. In addition, the prepared raw material oil is selected through a multi-stage selection system of 10 mesh, 20 mesh, 40 mesh, 60 mesh, and 80 mesh. The filter is used to filter, and after adding the combustion enhancer, it can remove coal powder, tar acid, and tar alkali, and can reduce the power load and completely remove impurities. The coal tar combustion oil can burn at 40°C.

Abstract

The invention discloses an allocating technique of fuel oil, which comprises the following steps: selecting coal tar through 10-order, 20-order, 40-order, 60-order and 80-order multi-grade filter to remove gel, tar and ash; inputting the raw material into oil water separating tank; heating to 70 deg. c; separating oil from water; transmitting the dehydrating raw material into reserving tank to blend with certain proportion of combustion adjuvant; filtering through 80-order to obtain the product.

Description

Technical field: [0001] The invention relates to a blending technology of fuel oil, in particular to a blending technology of coal tar fuel oil. Background technique: [0002] At present, coal tar is replacing mixed crude oil in steam injection boilers with the advantage of low price, but its effect is mediocre, and the main problems are as follows: First, the ash content of coal tar is relatively large, and the number of boiler soot blowing is relatively high. The second is that coal tar has little smell at low temperature, but when the temperature reaches 60°C, the volatile amount increases and the smell is relatively strong. Third, due to the high viscosity, coal tar can only be used above 60°C, which limits its use and increases the cost. [0003] At present, Liaohe Oilfield uses coal tar fuel oil to apply the technology of thermal recovery steam injection boiler. After doing a lot of experiments, the modulation method of coal tar is determined. First, it is considered ...
