How should low molecular weight at the press inlet be addressed?
Thread Content
Due to the low coking capacity, which is below 50% of the designed load, the inlet flow rate to the compressor is severely insufficient. To ensure the stable operation of the compressor and prevent surging, the opening degree of the anti-surge valve is set at 40–50%, as a result of which some light components undergo backflow. The molecular weight at the compressor inlet is 5 units lower than the designed value. What should be done in this situation?
With low processing volume, the only option is to activate the anti-surge mode; increasing the speed is a waste of energy!
Reduce speed～Slightly close the surge valve…Maintain outlet pressure
