On the reprocessing of water-containing contaminated oil in coking units
Thread Content
Regarding the reprocessing of water-containing dirty oil in coking units: Where is the reprocessing point for such oil generally located in the coking units of your refineries? Is it located on the feed pipe to the coke tower?
I know that generally quenching is carried out from the top; are there any manufacturers that feed coke into the tower from the bottom?
I modified my setup: all the oily wastewater from my system is first sent to the oil waste tank, where some of the water is removed. Then, it is fed through an opening in the quench oil line that leads to the top of the tower, rather than going directly to the top of the coke tower; instead, it enters the contact cooling tower, where it is used for cooling after increased steam supply to the coke tower. This allows the steam to remove the water content from the oily waste. The oil is then pumped from the bottom of the contact cooling tower into the raw material buffer tank, where it is reused along with the raw materials. The results are satisfactory; feel free to send a message if you have any questions.
