$37.$ The goal of crude oil stabilization is to minimize the content of $\_\_\_\_$ and $\_\_\_\_,$ thereby reducing the risk of $\_\_\_\_$ during storage and $\_\_\_\_.$

$38.$ The principle behind fractional distillation is the difference in $\_\_\_\_$ points among crude oil components, facilitating the production of $\_\_\_\_$ and $\_\_\_\_$ from the crude feed.

$39.$ ASTM distillation tests are essential for characterizing the $\_\_\_\_$ characteristics of petroleum products, guiding $\_\_\_\_$ practices and meeting industry $\_\_\_\_.$

$40.$ TBP and EFV distillation techniques offer insights into crude oil's $\_\_\_\_$ behavior under different conditions, informing $\_\_\_\_$ strategies and $\_\_\_\_$ operations.
