The flash point of hydrogen is 550°C; if this temperature is reached, any leak can lead to a fire or explosion. For safety reasons, it is specified that the heating temperature for hydrogen must not exceed 510°C.
Since the flash point of hydrogen is 550°C, reaching this temperature can lead to fires or explosions in the event of a leak; for safety reasons, the heating temperature for hydrogen is specified to be no higher than 510°C.

Because the solubility of hydrogen increases as temperature rises, more hydrogen dissolves in the oil, resulting in loss due to hydrogen dissolved in the oil, namely dissolved hydrogen loss.
Answer: Since the flash point of hydrogen is 550°C, reaching this temperature can lead to fire or explosion in the event of a leak; for safety reasons, the heating temperature for hydrogen is specified to be no higher than 510°C.
In hydrogenation units, there are regulations specifying that the heating temperature of hydrogen should not exceed 510°C. This is because the solubility of hydrogen increases as the temperature rises, resulting in more hydrogen dissolving in the oil; this leads to losses due to hydrogen dissolved in the oil, namely dissolved hydrogen loss.
