Catalytic cracking steam balance
Thread Content
The steam generated by the catalytic cracking unit is used internally within the unit before being sent out. When the steam production is too high and cannot be balanced, should the steam be vented, or should the unit reduce its operation to lower the steam output?

It is necessary to determine whether steam can be used throughout the plant. Our company plans to replace the back-pressure steam turbine with an electric motor, thereby addressing the problem of waste caused by excessive back-pressure steam. I hope it helps.
When it gets larger, check whether it’s possible to provide heating for the dormitory, or contact a few other companies to see if they need steam.
We have also encountered the situation mentioned by the poster; we try to avoid leaving things unattended in the same place, as noise can affect the surrounding environment. Adopt multiple pressure relief points, increase heating in the tank area, and use steam for oil collection and tank boiling. Generally, there is an excess of low-pressure steam. We will modify the excess steam generator so that it operates at medium temperature and pressure instead of high temperature, and the resulting steam will be sent to the turbine to drive the generator for power generation, yielding significant economic benefits.
Steam is money; how can it be wasted? Think of ways to make use of it comprehensively.
If it needs to be vented, then vent it; efficiency should be the priority – the volume cannot be reduced. However, the utilization of excess steam also needs to be considered. For example, selling it to other factories.
The accident state should prioritize safety; venting through a flare is the best option. Under normal circumstances, the steam balance needs to be optimized; this is not a problem related to a single device, but rather the result of optimization across the entire company. Typically, steam generator sets powered by oil are used in on-site power plants to balance the steam supply.
When the raw material used for processing is heavy and of poor quality, the amount of raw coke produced also increases; more heat is required for burning it, which results in more steam being generated. The remaining steam can be used for the overall steam balance of the plant; if there is still excess steam, it can be used to heat workers’ dormitories and for bathing purposes. If even more steam is left over, it can be vented.
Consider comprehensive utilization: if there is an abundance of low-pressure steam, it can be supplied to other heat users; if there is an abundance of medium-temperature and medium-pressure steam, steam power generation could be an option
Steam is a valuable resource that must be utilized comprehensively throughout the plant; any excess steam is fed into the plant’s low-pressure network to reduce the load on the boilers. Or he uses it
Steam cannot be vented, except in emergency situations. Contact the companies around you and sell it at a lower price. If time is tight, turn off the dry gas of the carbon monoxide incinerator while ensuring the processing volume
