According to statistics, after a continuous six-month sampling and analysis of flue gas from Changling Refining and Asphalt Production Plant, all emission targets have reached the national standard, which has well protected the working environment of the resident and staff.
In the production process of modified bitumen, some sulfur fume is produced, affecting the safety and environmental protection of employees and occupational health work of employees, and Changling Refinery set up a special technical research team.
Technical research team has to the same type of asphalt production units to learn about asphalt flue gas treatment process.At the same time, they produced on different bitumen flue gas production data acquisition, master the main components of bitumen flue gas.They combined with Changling refining Asphalt production cycle, asphalt fume composition and site layout of the plant, etc., and put forward six optimized schemes of water washing, pickling and burning of bituminous flue gas.
After the experiment and demonstration of each program, combined with the actual production, safety, operability, maintenance costs and other aspects of the program were evaluated to determine asphalt flue gas treatment measures .6 months, washing, pickling, combustion and modification Bitumen closed production of bitumen flue gas recovery system put into operation.
According to reports, through continuous adjustment and optimization of the system, all sulfur-fueled asphalt flue gas treatment furnace for combustion, the remaining gas after washing and pickling to ensure that the flue gas discharge standards.
