Problems solved by technology

[0006] In the existing analyzer system for hydrogen in carbon monoxide, when the methane in the measured gas reaches a certain value, it will interfere with the hydrogen analyzer, and the presence of argon will cause the hydrogen analyzer to produce a negative value, thereby triggering the hydrogen in carbon monoxide analyzer. chain, resulting in product production interruption
This is not in line with the requirement to ensure both CO quality and CO linkage supply to downstream customers

Embodiment

[0029] One: Determination of CH through a series of analogy methods 4 On the influence of the content of the hydrogen heat conductivity table in carbon monoxide, the relevant influence factors are obtained.

[0030] Equipment used:

[0031] Hydrogen content analyzer in carbon monoxide products (3-1711AT050.01, ABB EL3060Caldos27, 0-12500ppm), hydrogen analyzer 1 in raw synthesis gas (1501AT072, CALOMAT 6F, 0-100%), carbon monoxide analyzer in raw synthesis gas ( 1501AT073, ULTRAMAT 6F, 0-100%), methane analyzer 2 in raw syngas (1501AT074, ULTRAMAT 6F, 0-0.5%).

[0032] Adoption steps:

[0033] 1. Equipped with standard gas with methane content of 1%, 3.7%, and 5.9% in carbon monoxide;

[0034] 2. At the same time, the analysis instruments 1501AT072, 1501AT073, 1501AT074, 3-1711AT050.01 analyze various standard gases to obtain the following data:

[0035]

[0036] 3. Concluded: methane content greater than 5.8% will cause chain of hydrogen in carbon monoxide

[0037] Tw...

Abstract

The invention relates to a detection method for avoiding misoperation of a hydrogen analyzer, which is used to judge the hydrogen content in a CO product gas. The detection method comprises the following specific steps: (1) a hydrogen analyzer (1) and a methane analyzer (2) in parallel with the hydrogen analyzer (1) are arranged in a CO transmission pipeline; 2) the CO product gas enters the hydrogen analyzer (1) and the methane analyzer (2) simultaneously, and if the hydrogen analyzer (1) outputs signals to indicate the hydrogen content meets the standard, the pipeline is unobstructed; and 3)if the output signals of the hydrogen analyzer (1) are abnormal, in combination of the signals transmitted by the methane analyzer (2), whether methane generates influences on the hydrogen analyzer (1) is further judged. In comparison with the prior art, through adding the methane analyzer and a PLC, interference of methane and argon to the hydrogen analyzer can be avoided.

Description

technical field [0001] The invention relates to an analysis system and method, in particular to a detection system and method for avoiding misoperation of a hydrogen analyzer. Background technique [0002] The synthesis gas separation unit produces carbon monoxide products, and the pipeline transportation method is adopted to supply carbon monoxide products to customers of Hualin Gas. The quality indicators of carbon monoxide products are as follows. [0003] Carbon Monoxide Products: [0004] [0005] The hydrogen analyzer is generally a thermal conductivity analyzer. The measurement principle of the thermal conductivity analyzer is based on the physical characteristics of the gas thermal conductivity value and its composition. The content of each component in it. The thermal conductivity values ​​of various component gases in the existing gas are as follows: figure 2 shown. [0006] In the existing analyzer system for hydrogen in carbon monoxide, when the methane in...
