How a Gas Plant Works: Process, Control, and the PLC & HMI Systems That Run It

How a gas plant actually works - process and control, as one machine.A natural gas processing plant turns wet, sour, raw gas into pipeline-quality sales gas and natural gas liquids - and none of it runs on its own. How a Gas Plant Works treats the plant and the control system that runs it as a single machine, walking you from the inlet flange to the property line, and from the field transmitter to the operator's screen.Written for operators, instrument and electrical technicians, controls and process engineers, system integrators, and the new graduate trying to connect a P&ID to a tag database, it explains the real thing in plain language - with the actual numbers, standards, and failure modes that matter, and without ever talking down to you.Inside this book- How raw gas becomes sales gas and NGLs: separation, compression, amine treating, dehydration, cryogenic recovery, and fractionation- Field instrumentation, the 4-20 mA loop, and how a PLC really works- Control strategies: PID, cascade, feedforward, ratio, split-range, override, and compressor anti-surge- HMI and SCADA, High-Performance HMI design, and alarm management- Safety instrumented systems, SIL, voting, and the cause-and-effect matrix- Commissioning and loop checks, calibration, plant startup, and working safely on live systems- A full glossary, acronym list, standards reference, and instrument-tag keyFifteen chapters, dozens of clear engineering diagrams, and five reference appendices in a professional 8×10 format.From the black box at the inlet to the discipline that sustains a plant for decades - a clear, practical map of how it all actually works.
