Embodiment 1

[0028] Water coke slurry was prepared according to the mass percentage of petroleum coke: water: additive = 65.5: 34: 0.44, wherein, the specific content of each component in the additive is shown in Table 1.

[0029] Table 1

[0030]

[0031] For the preparation process of the above-mentioned water coke slurry, please refer to figure 1 The pulping process flow chart shown, its specific process is:

[0032] (1) Carry out a mechanical crushing of lump petroleum coke to particle size 8mm;

[0033] (2) Transport the once-broken petroleum coke to the crusher with a belt conveyor for secondary crushing to reach a powder with a particle size of 2mm;

[0034] (3) The pulverized petroleum coke is transported to the belt scale for continuous weighing by a belt conveyor;

[0035] (4) Add additives (dispersant and desulfurizer) and water into the ball mill through the weighed petroleum coke powder in proportion to carry out continuous wet ball milling;

[0036] (5) Petroleum coke ...

Embodiment 2

[0049] Water coke slurry was prepared according to the mass percentage of petroleum coke: water: additive = 65.4: 34: 0.6, wherein the specific content of each component in the additive used was shown in Table 1, and the preparation process was the same as in Example 1.

Embodiment 3

[0051] Water coke slurry was prepared according to the mass percentage of petroleum coke: water: additive = 60.9: 38: 1.1, wherein the specific content of each component in the additive used was shown in Table 1, and the preparation process was the same as in Example 1.

Abstract

The invention discloses a desulfurized water coke slurry composition, which comprises petroleum coke, water and additives. In terms of mass percentage, the water coke slurry composition contains 55-75% of petroleum coke, 24-44% of water, and 0.1-2% of additives; and the additive of the present invention further comprises a compound that reduces the viscosity of the water coke slurry. Dispersant, stabilizer to prevent hard precipitation of water coke slurry, and desulfurizer to reduce post-combustion sulfur dioxide emissions. The water coke slurry of the invention has better fluidity and stability, and can reduce the sulfur dioxide in the flue gas discharged after combustion.

Description

technical field [0001] The invention relates to a water coke slurry used in a combustion system and a preparation process thereof. More specifically, the invention relates to a desulfurized water coke slurry capable of reducing sulfur dioxide de-emission after combustion and a preparation process thereof. Background technique [0002] Water coke slurry is a liquid fuel prepared by adding water and additives through a specific process, using petroleum coke, a by-product of petroleum refining, as raw material. It can be used as an alternative fuel for thermal equipment fueled by oil and / or gas. Generally speaking, every 1.18 tons of petroleum coke can replace 1 ton of crude oil. Therefore, the promotion and application of water coke slurry can save scarce oil resources and achieve reasonable resources. use. Industrial experiments have proved that the cost of steam production by oil-fired boilers is 152.75 yuan / ton of steam (the price of crude oil is calculated at 2350 yuan / to...
