A sulfur recovery Claus furnace oxygen-enriched blast management system and method

Abstract

The invention relates to the technical field of petrochemical and coal chemical industry, and provides a sulfur recovery Klaus furnace oxygen-enriched blast management system and method. The sulfur recovery Klaus furnace oxygen-enriched blast management system comprises a compressor front oxygen interface safety device, a compressor and a compressor rear oxygen-enriched monitoring system; the compressor front oxygen interface safety device can mix oxygen and air in front of the compressor, and the process can be completed by using low pressure oxygen, no oxygen booster is needed, mixing is uniform, safe, and reliable, and cost is low; and the concentration, the flow rate, the temperature, the pressure, the electrostatic discharge and the particle filtration of oxygen can be strictly monitored and managed; optimization is realized through calculation using an oxygen-enriched uniform mixing monitoring module. According to the system provided by the invention, the whole oxygen enrichmentprocess is monitored through the compressor front oxygen interface safety device and the compressor rear oxygen-enriched monitoring system, so that the safe operation and the service life of the Klausfurnace can be ensured, and the hydrogen sulfide treatment capacity of the Klaus furnace is improved.

Description

technical field [0001] The invention relates to the technical field of petrochemical and coal chemical industry, in particular to a sulfur recovery Claus furnace oxygen-enriched blast management system and method. Background technique [0002] Since my country's petrochemical industry refines high-sulfur crude oil with high sulfur content and low price, and the natural gas produced in China also has high sulfur content, a large amount of hydrogen sulfide will be generated during the chemical reaction in the coal chemical industry. In order to protect the equipment, amine liquid is often sprayed in the production process to protect the equipment, so these hydrogen sulfide also contain amine components. At present, many natural gas and refining petrochemical plants are urgently required to improve the processing capacity of hydrogen sulfide. [0003] Claus furnaces are equipment used to remove hydrogen sulfide produced by burning fossil fuels. The principle is to make hydrog...

Problems solved by technology

[0005] However, the current low-concentration oxygen-enriching process of the Claus furnace uses high-pressure oxygen mixing after the compressor, and the pressure of the oxygen is required to be above 1.6MPa, which requires an oxygen booster, and the high-pressure oxygen has high requirements for the material of the pipeline equipment. The operating cost is greatly increased, and the high-pressure oxygen is very dangerous to safety, and it also affects the uniformity of mixing.
