Theoretical water output per hour during methanol temperature-raising reduction
Thread Content
Recently, the medium-pressure methanol in our synthesis process has been subjected to heating and reduction. The engineers did some calculations and said that the theoretical water output is 144 KG per hour; this figure is based on our circulation pump and system pressure. I’m not familiar with the specific calculation steps, so I’m hoping someone can help provide a detailed outline of them. Two circulation machines were started to raise the temperature, with an air injection rate of 12 m3/min; the reduction pressure was set at 5.0 MPA, and the catalyst volume used was 30 m3. I’m not sure how to calculate the water output per hour.
During the catalyst reduction process, the water removal rate must be in line with the water vapor concentration; generally, this concentration should not exceed 2 g/Nm3. With a pumping capacity of 12 m3/min for your circulation pump, the circulation volume during heating can be calculated as 72,000 Nm3/h. The water output per hour, denoted as Q (Kg/h), is then 72,000*2/1000 = 144 Kg
