Procedure of UOP 779 Test Method
The UOP 779 test method is a standardized procedure used to measure the yield of liquefied petroleum gas (LPG) from crude oil and other hydrocarbon streams. It is widely recognized in the petroleum industry and is an important tool for evaluating the quality and value of different feedstocks.
The test method involves several steps, beginning with the preparation of the sample. A representative sample of the liquid hydrocarbon stream is collected and filtered to remove any solid impurities or particulate matter. This ensures that the test results are accurate and reliable.
Once the sample is prepared, it is then heated in a specially designed apparatus called a vaporizer. The vaporizer heats the sample to a specific temperature, causing the hydrocarbon molecules to vaporize, or transform from a liquid to a gas state. The resulting vapor is then collected and measured to determine the yield of LPG.
The measurement of LPG yield is performed using a gas chromatograph, a highly sensitive instrument that can detect and analyze the individual components of the gas mixture. The gas chromatograph separates the different components of the vaporized sample and quantifies the amount of LPG present. This data is then used to calculate the yield of LPG from the original hydrocarbon sample.
The UOP 779 test method is widely used in the petroleum industry for assessing the quality and value of different hydrocarbon streams. It provides valuable information about the yield of LPG, which is an important product in the energy market. By using this standardized procedure, industry professionals can make informed decisions about the processing and utilization of crude oil and other hydrocarbon feedstocks.
