Abstract


Oil sludge is one of the main pollution sources for oilfield industry. The characteristics of oily sludge produced in different fields and the dehydration methods for oily sludge are primarily introduced. It usually consists of 10%-50% oil and 40%-90% water. It also consists of poisonous and harmful substance, if we discharge it random, it will bring dangerous to environment and health of people. So the oily sludge should be treated harmlessly or utilized comprehensively.The paper study a new type of oil sludge treatment technology was produced to realize multiple effects by analyzing the ingredients and potential energy of oil sludgy. This technology mainly mixes coal with oily sludge and straw to produce briquette for combustion and gas making. This technology make the best use of oil sludge heat value and realize innocent treatment, which means the environment problem and waste utilization are solved at the same time.This technology firstly appends 1-2% dispersant to cut down the viscosity of oily sludge from 7000mPa·s to 1000mPa·s. It can cut down oily viscosity sludge and make oily sludge floating, this avoid difficulty addition of oily sludge and choke the equipment. Then mix the oily sludge with coal to produce briquette. This technology makes use of the intrinsic viscosity instead of the briquette additive. Adding the 1% curing agent during produce briquette can enhance the ratio of briquetting and compression strength, it also decreases the sulfuret after combustion.The forming rate and three days resistance of straw briquette and gas briquette which produced by this technology can reach to 95% and 1.2MPa. The gas rate of gas oily briquette increase of 1.5-2 times.
