The waste gas generated during the production of raw ethylene glycol and ethylene oxide units contained gas such as ethylene, methane, and oxygen, and there was a large area of ​​leakage. The plant passed the project and used the 7.1th study of CSSC Group Corporation. The matured boiler technology, based on the full use of existing components, will reform the unreasonable structure of the original waste heat boiler with double-drum expansion contact, boiler incineration chamber and heat exchange chamber in the same space. After the transformation, the waste heat boiler has become a separate incinerator horizontal flue pipe waste heat boiler. Due to the use of an independent incineration chamber, the working conditions of the evaporator heat exchange tubes are improved, which can greatly increase the service life. The boiler system adopts an external structure of a fire tube boiler and a steam drum, the safety and reliability of the boiler are guaranteed, the structure is more compact, and the heat exchange effect is better. At the same time, the plant laid pipelines and introduced ethylene oxide plant exhaust gas to the boiler for recycling. After the waste heat boiler is operated, by recovering the exhaust gas of two sets of equipment, it can produce 2 tons or more of low-pressure saturated steam per hour, which not only realizes the recycling of resources, but also facilitates environmental protection and emission reduction.
Jilin Glycol Ethylene Plant Waste Heat Boiler Renovation Achieves 2 Million Years of Efficiency
Recently, Jilin Petrochemical Ethylene Glycol Plant has transformed the waste heat boiler of ethylene glycol plant to meet the requirements for incineration of waste gas from ethylene glycol and ethylene oxide plant and recovery of waste heat from flue gas. At the same time, energy saving and emission reduction are also very effective. Obviously, more than 200 million yuan will be created annually.
