| Oilfield oily sludge composition is complex,generally by the oil-in-water,invert,and suspended solid impurities,is an extremely stable suspension emulsion system,contains a lot of aging oil,wax and asphaltene,colloid,suspended solids,bacteria,salts,acid gases,corrosion products,etc.,also includes the production process of cic and flocculating agent,corrosion inhibitor,scale inhibitor,bactericide and other water treatment agent.In addition,the tertiary oil recovery,the implementation of polymer flooding in daqing oil field oil field polymer oil-bearing sludge contains chemical composition also contains weak acid in low temperature adhesive agent,polyacrylamide sulfide,etc.Because of oily sludge containing sulfur,benzene,phenol,anthracene,pyrene,etc have the stench of poisonous and harmful substances,and crude oil contains some hydrocarbons carcinogenic,teratogenic and mutagenic effects,oil field oil sludge has been listed as hazardous solid wastes(HW08),incorporated in the hazardous waste management.The sludge that meets the environmental requirements of the final disposal method has many kinds,including safety landfill,land use,burning,building building materials,etc.The sludge has a high concentration of organic matter,which can be used by direct(burning)or indirectly(in the form of a landfill).Oil field sludge is considered hazardous waste,cannot be used on the land,and is subject to restrictions on building materials.So maybe the way out is always a safe landfill and incineration.This article through to Mr North oilfield oily sludge composition analyses and studies the composition and characteristics,burning an approach to determine the north oilfield oily sludge treatment,and verify its feasibility,formulated the oily sludge incineration project proposal. |
