掺混劣质原油对电脱盐污水水质特征的影响
Effect of Adulterating Heavy Oil on Water Quality Characteristics of Electric Desalination Wastewater
摘要
Abstract
Heavy oil adulteration is an effective strategy to enhance the cost-effectiveness of refineries,but its effect on the water quality of electric desalination wastewater is still rarely reported.This study investigated the water quality characteristics of the electric desalination wastewater at blending ratios of 0%,25%,50%and 100%,using Saudi crude oil as the bulk crude oil and Napo heavy crude oil as the blended inferior crude oil.The results showed that the main polar organic compounds in the electric desalination wastewater at different blending ratios were lipids(24.5%~44.4%),aliphatics(17.2%~37.5%)and lignin/carboxylic acid-rich alicyclic molecular structure compounds(24.2%~56.8%),and the main non-/weak-polar organic compounds were phenols(12.4%~33.2%)and nitrogen-containing compounds(11.2%~21.8%).The concentrations of COD,total oil,conductivity,total nitrogen,and NH4+-N in the electric desalination wastewater were positively correlated with the blending ratio of Napo heavy oil.Napo heavy crude oil blending promoted the dissolution of nitrogen-containing non-/weak-polar compounds and O3S1-type polar compounds.The content in the electric desalination wastewater was higher than that of Napo heavy oil and Saudi crude oil.关键词
