Utilization of backpressure steam waste steam

Thread Content

The turbines in coking plants control the pressure of the backpressure steam to maintain a proper speed. However, when the backpressure steam is at a low pressure, it cannot be utilized, so it has to be vented. Could everyone please discuss ways in which this unused waste steam can be recycled? I have the following ideas, though I’m not sure if they are feasible: 1. Enhance heat exchange with the crude oil (by adding a heat exchanger) to recover the condensed water (which is still at a high temperature); 2. Exchange heat with the air entering the heating furnace; 3. Exchange heat with the stabilizing absorbent to increase the temperature of the rich fuel mixture; 4. Or simply add another condenser to recover the condensed water; 5. Raise the temperature of the sludge tank to improve the dehydration of the sludge. These are just ideas that came to mind – there is no actual data available. I hope everyone can offer some suggestions, and please feel free to point out any shortcomings. Thank you for your guidance!
