Reciprocating Compressor Performance — online
Know what your reciprocating compressor should deliver and draw, compare it with what it does, and see what the difference costs.
Yellow cells are inputs; orange cells are choices; blue cells choose the unit. Select or hover over an input to see its help in the box below the toolbar. The sheet is the same as the Excel tool (USD 49) — the Guide, method and references are in the Excel file.
What this reciprocating compressor performance calculator does
Single- or multi-stage (up to four stages) reciprocating compressor performance from the cylinder data: volumetric efficiency, capacity, power, discharge temperature, rod gas load and a comparison with plant readings.
- Up to four stages. Per-stage bore, stroke, rod, speed, clearance, single or double acting, valve and pulsation losses, leakage.
- Any gas or mixture. Library gases or up to 12 components with real-gas Z and k (Peng-Robinson); wet gas for intercooler condensate.
- Capacity and power. Volumetric efficiency, actual and standard capacity, stage ratios, discharge temperature with limit check, indicated and brake power.
- Rod gas load. Compression and tension as a percentage of your rating (gas load only, screening).
- Compare with readings. Measured flow, power and temperatures give implied leakage, deviations and the yearly cost of the gap.
- Capacity steps and what-if. Full load, head end, crank end and clearance pocket; suction pressure and speed cases.
How it was checked
Every result and message cell of the online tool was compared with the Excel workbook recalculated independently, at the default inputs and at four sets of randomly changed inputs, with the displayed text identical. The method and sources are those of the Excel tool and its Guide.
