Two compressors, one as a regulator – what impact does this have on the pressure in the downstream system?

The two compressors were originally connected in parallel; suddenly one of them developed a problem and stopped operating, while the other continued to run.
Logically, the system pressure should decrease, that is, the backpressure should drop. If the process permits, make adjustments in a timely manner, and the pressure should return. But the traffic will definitely decrease; it now depends on the capability of process operation. If the process conditions do not permit it, such as excessive temperature, etc. Issues such as non-compliance and shutdowns will occur.
The usual approach is to reduce the system pressure; if the original process pressure is maintained, insufficient space velocity will cause the temperature to build up in the bed, leading to overheating. Answer completed.
The pressure will definitely drop first; if the downstream system does not reduce its gas consumption, the pressure will not recover. If the downstream system reduces its gas consumption, the pressure will gradually return to normal
Since the poster has two units, it means there is a need for data traffic; can reducing the number of units to one ensure sufficient traffic? If pressure can’t be guaranteed, then nothing else can be guaranteed either! @
The back pressure of the compressor is what you refer to as the system pressure. The level of this system pressure is related to the amount of air supplied by the compressor; when the supply exceeds the system’s demand, the pressure rises, and when the supply is less than the system’s demand, the system pressure drops. When these two amounts are equal, the system pressure is balanced. In the situation you described, since the air supply has decreased, the system pressure will definitely drop. However, if adjustments are made in a timely manner to reduce the load on the system, the pressure can gradually reach a new equilibrium point, thereby maintaining constant system pressure.
The system needs to have its pressure reduced first; otherwise, the output temperature will become too high. Adjustments can be made later
