On June 28, 2017, the "Project of Dynamic Wave Desulfurization of Sulphur Recovery Tail Gas of Petrochina Changqing Petrochemical Company" undertaken by us was put into operation successfully. The project mainly focuses on the treatment of tail gas from ammonia-burning furnace and sulfur recovery tail gas. Since it was put into operation, it has been running well. Under the design conditions, all emission indexes (SO₂, NOx and COD) are up to standard, which is highly recognized by the Owner!
