Environmental improvement for atmospheric pressure gasification
Thread Content
For atmospheric pressure gasification, issues such as dust pollution and the environmental impact of discharging gasification cycle water outdoors pose significant challenges in terms of environmental protection. Please discuss what effective measures can be taken to address these pollutants without altering the gasification process
Where? The problem can definitely be solved through technical upgrades.
This technology is very common in small and medium-sized nitrogen fertilizer plants.
At atmospheric pressure gasification, dust pollution... The solution is: first, select coal varieties with good thermal stability, and screen to remove fine particles before feeding them into the furnace. The pollution caused by the open-air discharge of gasification cycle water... The solutions are to use coal types with low volatility such as anthracite and semi-anthracite, or to employ high-temperature gasification processes to increase the conversion rate. Carbon molecule vaporization technology can solve these problems (reducing such pollutants, improving conversion rates, saving energy, and reducing costs).
Atmospheric pressure gasification generally uses bituminous coal or coke; how should the gasification cycle water be treated?
Additionally, atmospheric pressure gasification often uses briquettes; due to technical issues with briquette production, there is a lot of dust
Carbon molecule vaporization technology is a continuous vaporization process using superheated steam + air, which can reduce the pollution caused by the top and bottom blowing in existing gap gas furnaces, while increasing conversion rates, saving energy (with an efficiency improvement of over 30% compared to existing gas furnaces), and reducing costs.
There are few batch furnaces left; both pure oxygen and oxygen-enriched environments are used for continuous gasification.
“”What is the difference between the carbon molecule vaporization technology, which uses a superheated steam + air continuous vaporization process, and the pure oxygen or oxygen-enriched vaporization methods currently in use?
