Embodiment 1

[0070] A petrochemical company in Shandong tried the alkylation product desulfurization and deacidification device of the present invention to separate impurities such as sulfuric acid and sulfuric acid ester contained in the alkylation reaction product, so as to ensure the safety of downstream production devices and optimize the production process. Reduce the cost.

[0071] Its specific operation and effects are described as follows:

[0072] The main parameters of the desulfurization and deacidification process of the alkylation product: the working pressure of the pickling separation tank is 0.5MPa, the added new sulfuric acid=98% by weight, the treatment capacity of the alkylation product is 13t / h, and the sulfuric acid content is 15% by weight, and the sulfuric acid Esters = 2 to 3% by weight.

[0073] Shown in the following table 1 pickling separation tank design physical property parameters:

Embodiment 2

[0086] The alkylation pilot plant of a petrochemical company in Hebei Province tried the alkylation product desulfurization and deacidification device of the present invention, and separated impurities such as sulfuric acid and sulfuric acid ester contained in the alkylation reaction product to ensure that the downstream production equipment The safe and optimized production process reduces costs.

[0087] Its specific operation and effects are described as follows:

[0088] The main parameters of the desulfurization and deacidification process of the alkylation product: the working pressure of the pickling separation tank is 0.6MPa, the added new sulfuric acid=98% by weight, the processing capacity of the alkylation product is 500L / h, and the sulfuric acid content=18% by weight, the sulfuric acid Esters = 1 to 2.5% by weight.

[0089] Implementation process:

[0090] process such as figure 2 shown.

[0091] Driven by the circulation pump, the fresh sulfuric acid and the al...

Abstract

The invention relates to an alkylation product desulphurization and deacidifying method and device, and provides an alkylation product desulphurization and deacidifying method. The invention further provides an alkylation product desulphurization and deacidifying device.

Description

technical field [0001] The invention belongs to the field of corrosion of subsequent equipment by organic sulfur compounds and free sulfuric acid carried in alkylation products, and relates to a method and device for removing organic sulfur compounds (such as sulfuric acid esters) and free sulfuric acid from alkylation products . Background technique [0002] Environmental pollution in today's world is becoming more and more serious, and environmental protection is generally valued by all countries. At home and abroad, with the rapid increase of automobile ownership, the air pollution caused by automobile exhaust is becoming more and more serious, and the environmental protection requirements of various countries are also becoming stricter, which puts forward higher requirements for the octane number and cleanliness of automobile oil. The high octane number, low sulfur content and other excellent performance characteristics of alkylated oil make it increasingly valued by va...
