Commingler

Combining two flow streams with a simple tee can lead to serious flow assurance issues such as:

• Weaker flow stream partially backed-out by stronger flow stream
• Pressure losses
• Backing-out of pump or compressor when combining gas and liquid streams
• Inadequate mixing of the two flow streams
• Ineffective friction reducer or corrosion inhibitor distribution
• Failure of the tee due to localised turbulence induced erosion/corrosion1

Drawing on our SJP technology, fluid dynamics experience and specialised models, Caltec unique proprietary* flow commingling solutions overcome the issues caused by tees:

• By using higher energy flow to create a drawdown on the low pressure stream, the backpressure imposed on the production stream is reduced
• Flow turbulence and pressure loss across the junction is minimised
• Differences in the pressure, flow rate, density or other properties of the two flow streams do not influence each other
• Minimised erosion
• Combine different phases i.e. gas, liquid and multiphase streams
• Extended life for critical tees
• Effective mixing
