[Question] Which is better for absorption in oil and gas recovery units: diesel or gasoline?
Thread Content
Which is better for the absorption tower of an oil and gas recovery unit: diesel or gasoline? Since only gasoline vapors are being treated, will using 90# gasoline for absorption have an impact on the quality of that 90# gasoline? Are there any disadvantages to using diesel absorption?
To handle gasoline vapors, only gasoline can be used for absorption; diesel cannot be used. Using 90# gasoline for absorption (a lower-grade fuel) has little impact on the quality of the oil. When carrying out recovery, the absorbed 90# gasoline is not sent back to the tank but is directly loaded onto vehicles and delivered to gas stations.
Reply to 2# caya Thank you! You mentioned that diesel cannot be used to absorb gasoline vapors – why is that? Could you explain it in more detail? Thank you very much!
Most of the components in gasoline vapor are the light fractions of gasoline, while such light fractions are rarely present in diesel. If the content of light components in diesel increases, it will affect the quality of the diesel.

It is better to use gasoline as an adsorbent; diesel is rarely used for this purpose, as its ability to adsorb the components of gasoline is too low, and it becomes saturated after a short time； 2. The mass of the saturated gasoline after adsorption generally does not change significantly; it is necessary to conduct tests and blending before it can be shipped out.
