  • Biological Treatment Technology of Oily Sludge
    2014
    Co-Authors: Long Wenyu, Zou Linlin, Shao Luhua
    Abstract:

    Abstract:- In petroleum refining and wastewater treatment process, petrochemical enterprises produce a large amount of oily sludge which mainly comes from the oil separator, flotation pool, biological activated sludge, the Tank of crude oil dehydration, oil Tank and Slop Tank etc. Therefore oily sludge can be divided into sludge from oil Tank, scum mud and landing mud. The sludge composition is so complex because of containing hydrocarbons, benzene, phenol, anthracene and other substances with the odor and toxicity. It’s generally made up of the oil in water, water in oil and suspended solids. And it has features of full emulsification, larger viscosity and solid hardly completely settling. With the continuous expansion of the scale of production equipment, these enterprises face also more environmental pressure when they make economic benefits. The resource utilization and harmlessness of solid waste is the important content for the construction of saving society. According to the new regulations and standards, it is difficult to meet the requirements for many enterprises in disposal of oily sludge, which results in increased enterprise pollution burden and highlighted environmental pollution problems. In this paper, the research status and development of oil sludge biological treatment technology were reviewed including bioreactor method, bioaugmentation method, biological land tillage method, biological flotation method and so on. All these methods were compared and commented before the future research suggestion were presented. Keywords:- Biodegradation, Oily sludge, Lab experiment, Oil removal rate, Harmless, soil I

  • Analysis of failed bottom plates of a wet Slop Tank
    2004
    Co-Authors: Ma Parameswara, Ma Venkataswamy, M Sujata, Sk Bhaumik
    Abstract:

    Cracked bottom plates of a wet Slop Tank were forwarded to the laboratory for analysis. Observations revealed that a number of cracks have initiated in the steel plates and propagated across the weld joints. The cracks were found progressive in nature. Analysis showed that the most probable reason for cracking of the plates was sulfide stress corrosion cracking, a form of hydrogen stress cracking.

  • ACCIDENT ANALYSIS ON THE FLASH EXPLOSION OF A LIGHT Slop Tank AND THE COUNTERMEASURES
    Petrochemical Safety and Environmental Protection Technology, 2014
    Co-Authors: Sinopec Qilu
    Abstract:

    Several fire and explosion accidents of the light Slop Tanks have occurred in China during the recent years.The causes were various,among which the spontaneous combustion of ferrous sulfide has drawn much attention.Meanwhile,it is indispensable to carry out the management measures to control and mitigate the hazard of ferrous sulfide.Through analysis on a fire and explosion accident of a light Slop Tank,this paper analyzes and looks into the technical and management reasons for the accident.It then presents pertinent countermeasures and measures.
