On March 12th, the first set of RTO furnace of VOCs control and modification project is safely put into operation by the energy-saving and environmental protection branch. Gas is not consumed by the system after ignition. It is self-sustained and burned by the collected by-product waste gas. The furnace temperature is maintained at 850°C. It meets with the design requirements and environmental protection requirements, the emission of non-methane total hydrocarbons is 25mg/m3 which is lower than the national standard emission of 60mg/m3.

This project is a key project of coking plant of Laiwu Iron and Steel Group. From design to commissioning, the duration is reduced from five months during the bidding to two months. The task is hard and we are pressed for time. All members of the energy-saving and environmental protection branch are involved in the job. There is clear division, everyone performs his own tasks and work overtime to complete the task. There are many exhaust points in this project, the existing drawings and documents are inaccurate, and the VOCs project is a key project. The leaders arrange the designers to work on site in time; participants are doing the design while visit the site, discuss the process optimum proposal and encounter difficulties one by one. The concentration of non-methane total hydrocarbons of emission reaches the standard at one time which is highly recognized by the owner. It also fully demonstrated our team's spirit of courage, fighting, and dedication. The completion of this project has great significance for our subsequent market promotion in the field of by product VOCs control and modification.
