PlantHand

Built by a gas plant operator. Works in the dead zone. PlantHand is the set of calculators and reference tables a processing plant or pipeline operator actually reaches for on shift. The same estimates you already work out by hand, done faster and more consistently, with the published method named on every result. Hydrates and injection - Hydrate formation temperature - Methanol injection rate - EG injection rate Pressure and temperature - JT drop / letdown check - Turboexpander - Blowdown time - N2 purge - Propane refrigeration Volumes and flow - Line fill - Vessel volume - Gas velocity - Flare rate / tip check Reference - Pipe schedule - Gas properties - Unit converter tuned to plant work - Glossary Every calculator names the published correlation behind it and links to the source, so you can read the theory rather than trust a black box. Where a method has a published validity range, a result outside it is flagged. Where a method carries a standing constraint, such as a sweet-gas-only assumption, that is stated with the result. This is a field estimation tool. It is not engineering design software, it does not produce a certified or stamped result, and it is never the sole basis for a safety-critical decision. Verify every number against your facility's approved methods. Dark for the control room, high-contrast light for direct sun. Big touch targets for gloves. Your last inputs are remembered. No account. No analytics. No data collected. Calculators run entirely on your device. Method references open in Safari only if you tap them. One price. Everything included. No subscription, no unlock packs.
