Flow Improvement

“Flow Improvement” in Crude oil pipelines

I. Description
Improving flow of High Paraffinic and ashphaltinic crude in flowlines/pipelines. The crude oil flow in the pipelines involves flow of fluid of the following nature

1. High Paraffinic and/or Asphaltenic crude oil
2. High WAT / Pour Point
3. Low Ambient temperatures
4. Non-piggable pipelines
5. Long tied-back flowlines

II. Boundary Conditions

1 Paraffin Content in Crude Oil : 25% by wt
2 Asphaltene Content : 3% by wt
3 Wax Appearing Temperature (WAT) : ~60°C
4 Pour Point : ~42°C
5 Ambient Temperature : 4 °C
6 Subsea Non-piggable pipeline sizes : 5 Km and above
