The feed oil used in hydrocracking units contains a high proportion of light components. While ensuring product quality, could this lead to excessive vaporization of these light components, thereby affecting heat exchange efficiency? This might result in lower heat exchange temperatures, reduced output flow, and an increase in liquid level. Is the specific heat capacity of light components lower than that of heavier components?
It will not affect the heat exchange efficiency, but there will be more light components in the high-grade product. Excessive light components hold little value when used in hydrocracking; an excess of light components can be used in atmospheric-pressure processing, which is cost-effective and yields good results.
By light components, I mean light oil, not the gas-phase components
When light oil is added to the feed and fed into the cracking reactor, it can be easily cracked to produce light components such as C2, C3, and C4.
