Problems solved by technology

[0003] Acid gas is a good gas fuel with high calorific value, but because it contains sulfur and other harmful components, it cannot be directly used as a common fuel gas, so it can only be burned in vain, which is a waste of energy and damages the environment. environmental pollution

Embodiment Construction

[0017] The acid gas from the refinery is collected and transported through pipelines to the shaft kiln of the cement plant as a fuel for combustion, which can completely replace the original coal fuel, and can also be used as an auxiliary fuel to save coal consumption. When the acid gas is burned in the kiln, the harmful component hydrogen sulfide chemically reacts with the cement material to form cement clinker calcium sulfate, which becomes a cement component, and other harmful components are also transformed through sintering.

[0018] The chemical formula is:

Abstract

The treating process of acid gas from oil refinery features that acid gas is used as the fuel in vertical kiln of cement mill. During the burning of acid gas in the kiln, the H2S component and cement material react chemically to produce CaSO4 while the other harmful components are sintered and converted. The treating process eliminates acid gas pollution radically while providing partial fuel for cement mill, reaching dual purpose of protecting environment and saving fuel.

Description

technical field [0001] The invention relates to a treatment method for acid gas in an oil refinery. Background technique [0002] The refinery will produce acid gas during the production process, the main harmful component of which is H 2 S, very easily pollutes the atmosphere. Refinery generally treats acid gas by burning it in torches or sending it to ground incinerators for incineration, but the flue gas after combustion still contains a certain amount of S, which still pollutes the atmosphere and cannot fundamentally solve the problem. In order to remove S in the acid gas, it is often necessary to take corresponding treatment measures, such as alkali washing or using other desulfurizers, the cost of desulfurization is relatively high, and the refinery also has different sulfur content in the acid gas for different sulfur-containing raw materials. different. Therefore, its desulfurization treatment is troublesome, and its effect is not necessarily ideal. [0003] Acid...
