Process pump trainer
In oil industry, crude oil is extracted from a well and then pumped for further processing. In the process pump trainer (PPT) three different pump types are operated and compared in various operation modes. The working medium is a mixture of air, water and oil to simulate crude oil. The trainer consists of three pump units and one supply unit. Each pump unit is equipped with two identical pumps. Pump operation in line or parallel is possible.
After passing the pump section, the synthetic crude oil is split into oil, water and air by phase separation and is then re-mixed to ensure its homogeneous composition.
Operating modes of the pump units
Pump unit 1: Single stage centrifugal pumps
- one pump in single operation
- two pumps in parallel operation
- two pumps in series operation
Pump unit 2: Multistage centrifugal pumps
- one pump in single operation
- two pumps in parallel operation
- two pumps in series operation
Pump unit 3: Multiphase twin screw pumps
- one pump in single operation
- two pumps in parallel operation
