摘　　要：南海某FPSO终端首次使用紧凑型气浮选装置,在运行初期出现两级气浮罐排污路相互干扰的情况,经流程改造后,二级除油率提升15%。在运行一年后,气浮罐出现处理量下降、液位下降等异常情况,开盖发现气浮罐内部腔室过滤孔板出现油泥堵塞。本文提出快速清洗方法,针对油泥堵塞的情况提出气浮罐改进的设计,可快速解决油泥堵塞的问题,对紧凑型气浮选器长期稳定运行有借鉴意义。A compact gas flotaion was used in an FPSO terminal in the South China Sea for the first time.At the beginning of operation,the sewage lines of the two-stage gas floating tanks interfered with each other.After the transformation process,the two-stage oil removal rate increased by 15%.In one year after the operation,air floatation tank capacity decline,liquid level drops,such as abnormal situation,open found gas floatation tank internal chamber filter orifice in sludge plugging,this paper puts forward fast cleaning method,aiming at the condition of the sludge plugging gas floatation tank improved design,can quickly solve the problem of sludge plugging,long-term stable operation of compact air flotation has reference significance.
