The flow controller senses the flow of liquid hydrocarbons from the sour oil drum and adjusts this flow with a control valve. A low level on the sour oil drum was tripping the unit every 3 hours, ...

Opposite of tip two above, an over-sized control valve or damper will typically require lower gain and integral PID settings. For example, a drum level control system where the feedwater valve is ...

• Case No. 1. Flow rate was 823 b/d, with 43% bs&w and GOR of 1,244 scf/bbl (Table 2). Fig. 2a shows the separator operating level before and after putting the feed control valve in service.

Quality calibration: SmartTrak’s NIST traceable accuracy is supported by Sierra's ten points, key standard calibration over the whole flow range. The controller has a robust and flexible control valve ...
