METHOD AND DEVICE FOR THE METERED ADDITION OF FLUIDS INTO REACTION VESSELS

摘要

The invention relates to a metering system (105) for the metered addition of at least one fluid (31, 31') at a certain first metering rate (DR1) from at least one reservoir (30) into one or more reaction vessels (2, 2'), comprising at least one metering device (87, 87', 54), means for determining a first pressure (p1) downstream of the metering device (87, 87', 54) and means for determining a second pressure (p2) upstream of the metering device, a device for pressurization (46), wherein the device is suitable for pressurizing the fluid in the reservoir (30) at the second pressure (p2), a control device (99), wherein the control device (99) is suitable for setting at least one control value (SW) for the metering device (87, 87', 54) on the basis of a pressure differential between the second pressure (p2) and the first pressure (p1) and the determined first metering rate (DR1), and metering rate determination means (135, 136), wherein the metering rate determination means (135, 136) are suitable for measuring a second metering rate (DR2), and the control device (99) is suitable for adjusting the at least one control value (SW) on the basis of a differential between the first determined metering rate (DR1) and the second measured metering rate (DR2).
