Why is the high-temperature product oil used in the tube side of the heat exchanger in the hydrogenation unit, rather than the low-temperature feed oil? ?
High-temperature oil is generally clean, does not easily clog pipes, and does not increase pressure loss in the oil circuit. High-temperature pipelines facilitate heat transfer, reducing large-scale heat loss in the shell side.
