Embodiment 1

[0007] Example 1: The upper part of the desulfurization tank is filled with zinc series desulfurizers, and the lower part of the desulfurization tank is filled with zinc, molybdenum and copper series desulfurizers, and the ratio is 3.6 to 1. Natural gas with a temperature of 360°C and a pressure of 1.8 MPa enters from the upper part of the desulfurization tank, and after inorganic desulfurization, organic desulfurization is carried out. After 19 seconds, the desulfurized natural gas is discharged from the bottom of the desulfurization tank and enters the subsequent process. The inorganic sulfur desulfurization rate is 99.97%, and the organic desulfurization rate is 99.99%.

Embodiment 2

[0008] Example 2: The upper part of the desulfurization tank is filled with zinc series desulfurizers, and the lower part of the desulfurization tank is filled with zinc, molybdenum and copper series desulfurizers, and the ratio is 8.5 to 1.5. Natural gas with a temperature of 300°C and a pressure of 1.3 MPa enters from the upper part of the desulfurization tank, and after inorganic desulfurization, organic desulfurization is carried out. After 56 seconds, the desulfurized natural gas is discharged from the bottom of the desulfurization tank and enters the subsequent process. The inorganic sulfur desulfurization rate is 99.95%, and the organic desulfurization rate is 99.97%.

Embodiment 3

[0009] Example 3: The upper part of the desulfurization tank is filled with zinc series desulfurizers, and the lower part of the desulfurization tank is filled with zinc, molybdenum and copper series desulfurizers, and the ratio is 5 to 1.8. Natural gas with a temperature of 320°C and a pressure of 1.6 MPa enters from the upper part of the desulfurization tank, and after inorganic desulfurization, organic desulfurization is carried out. After 38 seconds, the desulfurized natural gas is discharged from the bottom of the desulfurization tank and enters the subsequent process. The inorganic sulfur desulfurization rate is 99.95%, and the organic desulfurization rate is 99.98%.

Abstract

The invention discloses a desulfurization process of a hydrogen production system and relates to the technical field of chemical production. The desulfurization process solves the technical problem that hydrogen must be returned to the desulfurization process based on the existing hydrogen production system. The desulfurization process comprises installing a zinc desulfurization agent on the upperpart in a desulfurization tank, installing zinc, molybdenum and copper desulfurization agents on the lower part in the desulfurization tank, feeding natural gas at 260-360 DEG C under pressure of 1.3-1.8MPa into the desulfurization tank from the upper part of the desulfurization tank, carrying out desulfurization for 19-56s and feeding the desulfurized natural gas into later processes. The desulfurization process utilizes simple equipment, realizes a low operation cost, has good desulfurization effects and is widely used in the chemical industry.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a process for removing inorganic sulfur and organic sulfur in a hydrogen production system. Background technique [0002] The desulfurization process of the existing hydrogen production system is to use cobalt molybdenum hydrogenation process to remove organic sulfur and zinc oxide process to remove inorganic sulfur. Using this process requires more equipment and large investment, and it is necessary to return the produced hydrogen to the raw material of the system For the air part, the operating system is complex and has high performance. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a desulfurization process for a hydrogen production system. The desulfurization process is improved, and the desulfurization equipment is simple, the process is simplified, and hydrogen does not need to be returned to ...
