超临界 CO2萃取废弃油基钻屑的实验研究
Experimental study on waste oil-based drilling cuttings by utilizing supercritical carbon dioxide extraction technology
摘要
Abstract
In this paper ,supercritical carbon dioxide was used as an extracting agent to recovery the oil from the oil‐based drilling cuttings .By setting the residual oil contents as the main evaluation index , the effect of several factors including extracting pressure , extracting temperature , and extracting time were investigated .The results showed that the residual oil content was 0 .748% when the extracting pressure was 25 MPa ,the extracting temperature was 50 ℃ ,and the extracting time was 100 min .This extraction technology shows a favorable treatment efficiency .关键词
