Determination of Water Rate in Gas Oil and Fuel Oil by Extraction with Betacarotenes Molecules Using a Heavy Oil Clevenger Extractor, Process Validation by SPC

摘要

Water rate in hydrocarbons such as gas oil and fuel oil was determined by extraction with betacarotenes molecules at temperature between 120°C and 140°C using a heavy oil Clevenger extractor. This extraction was investigated like a process and the water rate data of gas oil and fuel oil was exploited using Statistical Process Control tools. We noticed that for gas oil and fuel oil, data follow a normal distribution. That is to say, this hydrocarbons water rate determination process by extraction with betacarotenes molecules using a heavy oil Clevenger extractor is statistically in control. So, the outcomes of the process can be accurately predicted depending on the volume of gas oil or fuel oil to be characterized. According to the Gas oil and fuel oil Total service specification target with heavy oil Clevenger extractor tolerance and standard deviation this water rate determination process is apt and able to produce water rate results with quality six sigma. The water rate in Malagasy station imported gas oil (800ml) and fuel oil (200ml) are respectively 0.1476ml and 0.475ml. We notice that after use the betacarotenes molecules are recycled.
