What is the impact of separation efficiency on the synthesis reaction?
Trace amounts of methanol have little impact on the synthesis reaction; however, if the water cooling is inadequate or the separation process is poor, the methanol content in the gas will increase significantly, which is very detrimental to the synthesis reaction. Firstly, the load on the centrifugal compressor increases, causing the motor current to rise; in severe cases, the impeller and blades can be damaged. Secondly, when gaseous methanol enters the synthesis tower, the most noticeable effect is a rapid drop in temperature at the top layer of the catalyst. If liquid methanol enters the synthesis tower, the synthesis reaction deteriorates during vaporization, the tower pressure rises, and in some cases overpressure forces an evacuation.
Increased power consumption; in severe cases, liquid hammer； To a certain extent, the reaction is suppressed, and methanol re-vaporization affects the inlet temperature.
