Abstract

Analysis of wax appearance temperature and wax dissolution temperature for light
and heavy crude oils is to have an experimental research regarding the properties of
light and heavy crude oils depending on some parameter which is wax appearance
temperature and wax dissolution temperature. Based on the real industry, the crude
oils naturally will be solid in certain temperature due to the circumferences and
surrounding factor. The purpose of this research is to analyse the crude oils properties
and hysteresis process. Therefore, the research will conducted by using rheometer.
The samples of crude oils been request form PRSB, Bangi and PPM, Melaka. There
are two types of light crude oils and three types of heavy crude oils. The equipment
been used to complete this research is rheometer. Rheometer been used in laboratory
located at block 20 is Discover Hybrid Rheometer (DHR) and been assisted by
graduated assistant at block 20. DHR could show the pattern of the curve according
to the parameter been setup and the WAT and WDT could be identify at the moment
the flow curve change.
The range of the WAT and WDT for light crude oils are 32 oC to 36 oC and 36 oC to
40 oC while the heavy crude oils are 5 oC to 24 oC and 15 oC to 32 oC. There was
difference range between light and heavy crude oils it might because of
composition of wax in the crude oils. It’s also may be affected by the density of the
crude oils.
As the conclusion, the objective been achieved. The best crude oils is lower WDT
and WAT which is heavy crude oils 2 5.35 oC and 15.98 oC based on seabed
condition in Malaysia which 15 oC.
