| Abstract: | According to corrosion types,positions,causes and coking hazard that happened to the equipments in furfural refining unit of No.1 Lube Oil Workshop of SINOPEC Maoming Petrochemical Company during the maintenance over the years,based on the corrosion mechanism and unit's characteristics,it is clarified that the corrosion is caused by phase change vortex corrosion and flushing,as well as furfural acid.In the mean time,factors leading to equipment corrosion are found out,such as feedstock degassing,feedstock property,phase change,furnace temperature control,equipment materials,etc.And a series of available measures are proposed to protect the equipments from corrosion and coking,with a remarkable success. |
| Keywords: | furfural refining corrosion coking prevention |
