What is the effect of using MC30 with high volume of distillate? Example you got the test results as follows:
At 225C is 62%, 260C is 80% , 360C is 57%
To assess the effects of using MC30 with high volumes of distillate at varying temperatures (225°C, 260°C, and 360°C), a general understanding of distillation and its application is necessary. From the provided distillation data, we can interpret the following trends:
At 225°C, 62% of the distillate volume is collected. This temperature likely corresponds to the fraction of lighter hydrocarbons or more volatile components being separated from the mixture. Higher distillation output is expected at this temperature due to lighter fractions.
At 260°C, 80% of the distillate is collected. This indicates that most of the components present in the MC30 (cutoff material) are vaporizing around this temperature. It suggests that the distillate contains medium-weight hydrocarbons, which are effectively captured at this temperature.
At 360°C, only 57% of the distillate is collected. The drop in distillation yield at this temperature implies that fewer heavy hydrocarbons are left to be vaporized. The components that remain at this temperature are likely heavier and more difficult to distill, leading to a reduced distillate volume.
These results imply that the use of MC30 with a high volume of distillate varies with the boiling points of different hydrocarbons. Most of the distillate is captured at around 260°C, with lighter fractions at lower temperatures and heavier ones being more resistant to distillation at higher temperatures.
Distillation is always a issue. specially to 437°F (225°C) as its mostly >30, and to 500°F (260°C) which is mostly around 65. can give suggestion how to overcome ?
Dear Sheikh Waqar Adeel,
Thank you for reaching out with your concerns about distillation temperatures in the production of cutback bitumen MC-70. Distillation issues at the temperatures you’ve mentioned can indeed be challenging, particularly with the specific fractions you are achieving.
To better manage distillation at these critical points, consider the following suggestions:
Temperature Control: Ensure precise control of your heating rates and maintain stable temperatures within your distillation unit. Advanced control systems can provide the necessary accuracy to avoid overheating or underheating.
Feedstock Quality: Verify the quality and consistency of your raw materials. Impurities or variations in composition can affect distillation performance and the boiling point ranges.
Equipment Check: Regular maintenance and calibration of your distillation equipment can prevent performance issues. Check for any wear and tear or scaling, which might impact heat transfer and temperature regulation.
