In petroleum chemistry, waxy oil from paraffins can cause operating problems for oil production. The chemical method is used to remove by using chemicals or additives to prevent the wax problem. In this study, the performance of wax inhibitor are evaluated by the measurement of pour-point reduction and wax deposition of crude oil from Mae Soon area...

... wax deposition of hexane, the experimental temperature is performed from 25 ° C to 45 ° C and the hexane concentration is from 0-15 %. As shown in Figure 2, the results present that at 25 ° C, the amount of wax has been reduced to 83.38 %, 91.78 % and 92.56 % for 5 %, 10 % and 15 % hexane, respectively compared to original oil. Also, at higher temperature like 35 ° C and 45 ° C, the amount of wax is lower because wax becomes more liquid and at 45 ° C, the amount of wax is at 53.99 %, 54.75 % and 55.37 % lower than original for 5 %, 10 % and 15 % hexane, respectively. ...

Global demand for crude oil has grown significantly over the past two decades. However, conventional light crude oil production is declining, and more and more deposits of heavy and waxy oil, including high waxy ones, are being developed, creating new technological challenges at every level of the process, from production to transportation and refining. Among the various problems, the main one is wax deposition. Since the costs of maintenance, repair, and achieving the required low-temperature properties of commercial oil products are very high, solving this problem becomes critical. The paper discusses the existing problems of production, transportation, and refining of waxy crude oil and analyzes the methods of their solution.
