Raw Gas Flow to Amine Contactors

After the raw gas flow leaves the Inlet Gas Filter (FI-1105), the raw gas flow branches to feed the two, parallel Amine (PV-1101A/B) contactors (see Figure 2). The equipment numbering described below is for contactor A but contactor B is exactly the same.

The flow to the Amine contactor (PV-1101A) passes through a meter run that monitors and controls the raw gas flow to each Contactor. The meter run consists of the following equipment to monitor and control the raw gas flow to each contactor.

  • Ultrasonic flow transmitter: this flow transmitter calculates the basic raw gas flow rate from the gas flow.
  • Temperature transmitter (TI-1023) and a pressure transmitter (PI-1023): these pressure/temperature transmitters provide data which allows the basic flowrate to be converted to the compensated raw gas flow rate.
  • Raw Gas Flow Control Valve: The feed gas flow rate for each amine contactor is controlled by a pre set flow control valve. The flow control valve (FV-1021) maintains the calculated set point that is used from the Ultrasonic flow transmitter and respective temperature and pressure transmitters.
