The speed-down operation saves diesel hydrosteam consumption
Recently, Maoming Petrochemical Company invented a set of "speed reduction operation method", which "reduced" benefits in production
.
Applying this method, the speed of the cycle machine of the No.
2 diesel hydrogenation unit in the workshop has been reduced from 8600 rpm to 7600 rpm
.
After deceleration, the device can save 4 tons of medium-pressure steam per hour, according to the medium-pressure steam of 207.
96 yuan / ton, the annual cost saving is more than 7.
29 million yuan
.
"The so-called speed reduction operation method is to make corresponding changes
to the speed of the circulator according to the actual processing capacity of the device under the condition that the oil ratio of the device meets the process requirements, by controlling the hydrogen purity of the post-circulating hydrogen by more than 85%, and reducing the content of hydrogen sulfide by turning off the bypass of the small cycle hydrogen desulfurization tower.
