Compressor Throughput Analysis Software™ (CTAS™) is a field compression monitoring and planning tool.

CTAS™ allows a planning engineer to determine the best way to configure future field production given various compression configurations.

CTAS™ can model and report on actual vs. expected compressor performance, providing a timely indication of compressor performance degradation.

Applications

Field Planning:

CTAS™ can be used to evaluate:

• Available Capacity in each Compressor Stage (Ullage)
• Contractual Entry Pressures
• Field Production Capability
• Power Requirements

On-line Monitoring:

• Estimates Power Usage
• Outputs Historical Trends
• Alarms on Abnormal Trends
• Predicts Polytropic vs. Actual Head
• Predicts Polytropic vs. Actual Efficiency

Features

CTAS™ is a field compression monitoring and planning tool. It gives operators valuable information on the peformance of compressor facilities, alerting them any potential problems by providing comparisons of actual vs. expected compressor performance.

Host Facility and/or Delivery Points

Automated Dew Point Calculation System™ (ADPCS™) provides operators with a tool to perform automated calculations and display of dew points of gas streams, using real-time composition data from on-line chromatographs.

Features

ADPCS™ allows real-time, on-line calculation and monitoring of water and hydrocarbon dew point based on gas composition and pressure measurements. The dew point is used to check contractual delivery of gas at custody transfer points.

Based on a field-verified fully-compositional thermodynamics simulation package, ADPCS™ simulates the phase behavior amongst vapor, hydrocarbon liquid, and water phases to determine the coresponding phase boundaries.

Designed to communicate with SCADA/DCS systems, ADPCS™ employs robust error checking protocols to ensure on-line stability.
