Cryo Plant Potential
Realize Cryo Plant Hidden Potential and Profits!
Barry D. Payne & Associates, Inc. offers Advanced Regulatory Control strategies designed for multiple platforms that deliver plant improvements with your current controls today!
Rate Processing Management
Automatically adjusts Plant Rate to meet Inlet or Residue Pressure and Processing Volume requirements at lowest practical Tower pressure to maximize recovery. Limiting logic maintains Tower and Recompression conditions at safe levels.
C1/C2 or C1 Composition Control
Advanced control of NGL product composition provides on-spec NGL production day or night, attended or unattended. Strategy utilizes onstream analysis (single or multi-stream), Tower pressure, Expander operating conditions, and several other factors to reduce overstripping losses and Methane give-away. Proven by years of service at several sites.
“Cold Spin” Protection
Cold Separator liquids rate is used to drive a Tower flooding prevention strategy, allowing operations to “push” temperatures colder around the clock. This strategy reduces low recovery operation due to cold spin upset and subsequent warming up, using the JT valve or other means.
Chiller Level Management
Reduces or eliminates Chiller propane “carry-over” due to poor level control during load change, permitting operation at efficient covered tube bundle levels for fuel savings and maximum capacity.
GPPC & GPRC
GPPC and GPRC Technology Targets Gas Plant Performance
Barry D. Payne & Associates, Inc. offers Advanced Process Control strategies designed for multiple platforms, that deliver plant improvements with your current controls today!
On Target Solutions include Advanced Gas Processing Control technology that delivers performance comparable to, or better than complex multi-variable control packages. This technology runs in your DCS, or your PLC, or can be scaled down to a Multi-Loop Controller, and requires no host or supervisory computer. Ongoing maintenance costs are significantly less than multi-variable controllers, while the installed cost of BDP On Target Solutions is typically less than 25% of a multi-variable control software application.
In Cryogenic Demethanizers, the controls incorporate two major elements:
- GPPC – Gas Processing Performance Control – with C1/C2 or C2/C3 Composition Control and Cold Separator temperature control for maximum liquids recovery – combining inputs from an Onstream Analyzer, DeC1 Pressure, Inlet Gas Flow, Expander Outlet Temperature, and Reboiler Duty calculations to yield stable, reliable composition control and recovery from upsets. In a recent paper, the GPPC controller was compared to a multi-variable controller costing in excess of six figures. Standard deviation of the liquid to volume ratio C1/C2 data for the two strategies differed by only 0.15%, even though the total cost of the BDP On Target Solution was less than $20,000.
- GPRC – Gas Processing Rate Control – with the composition under control, this Capacity Controller manipulates Cryo Processing Pressures and Recompressor Speeds or Recycle valves. It seeks whichever limit (Inlet/Residue Pressure or Treating/Cryo Flow) is currently in effect, while being constrained from lowering Tower Pressure below “Coldspin” or Recompressor limits (Surge, Low Suction Shutdown, or Rod Loading). This results in minimum pressure at any rate, normally maximizing recovery. If fuel costs outweigh Ethane values, the order can be reversed, minimizing Recompressor horsepower at any throughput. The GPRC controller has been utilized to balance parallel Cryo Plants with shared or split recompression, without wasting horsepower on “back-pressure” valves or other means.

GPFrac Technology Targets Gas Plant Performance
Barry D. Payne & Associates, Inc. offers Advanced Process Control strategies designed for multiple platforms that deliver plant improvements with your current system today!
On Target Solutions include Advanced NGL Fractionation Control technology that delivers performance superior to conventional advanced control. This technology runs in your current DCS or PLC, and requires no host or supervisory computer.
Whether your facility operates a single Y-grade (EP mix) splitter, or a multi-tower “Frac” train through DIB and Gasoline, most NGL fractionation processes can benefit from our simple but effective GPFrac strategies.
- Increase yields of higher-value product and reduce energy costs, or
- Increase throughput up to equipment limits.
Some or all of the control system-based strategies can be commissioned at a fraction of the cost it takes to actually install the DCS or PLC and field devices.
Integrates chromatographs, Pressure-compensated temperature and models with material balance and separation-based control.
Relaxes control of less-valued product when necessary.
Load Change Management
Feed forward signals are incorporated into decoupled control strategies that smoothly handle upstream disturbances.
Process Limit Controls
Delta P, Product Loss, Reflux, Tower Pressures, Hot Oil System Demand, Refrigeration Load, etc.
Weather effects on Air Condensers; Hot Oil, Refrigeration, or Waste Heat Changes.
The GPFrac strategies have been utilized to automatically keep the plant on target while operators deal with plant upsets such as compressor trips, heater trips, or amine system problems.
