The document discusses how gas analyzers are integrated with automation systems for real-time control of oil and gas operations. It describes a system that currently produces 40,000 bbls of oil, 20,000 bbls of natural gas liquids, and 230 million standard cubic feet per day of natural gas. The quality of gas streams is maintained through real-time analysis of the permeate gas stream, as off-spec gas could shut down the entire production system. It also details a gas treating unit that removes CO2 from residue gas streams using analyzer results to control inlet and outlet blending valves for the single operating column.

2. Oil and Gas Application
• Current production: 40,000 bbls oil, 20,000 bbls NGL,
and 230 mmscfd natural gas production.
• System is linked on common Plant inlet and Outlet
headers.
• Quality maintained via Real Time Analysis of Permeate
Gas Stream.
• Off-Spec Sales Gas has ability to take down all gas
plants, NGL, and Oil production system wide.

3. CO2 Gas Treating Unit
• Gas Treating Unit: Strips CO2 from Residue Gas stream &
currently treats 180 – 200 mmscfd.
• System is operated with one column and controller connected
to DeltaV DCS & uses real time analysis.
• Analyzer results are used to control inlet and outlet blending
valves.

4. Gas Treating Unit
Monitor plant Inlet/Outlet & individual skids
Currently analyzes 28 different streams on a configurable auto cycle
Has the ability to analyze up to 42 different streams in manual mode operation
Monitors Standard Residue Gas & Permeate Gas (High CO2, Hydro Carbon)
