The oilfield three‑phase separator is core process equipment for surface treatment of oil‑gas production. It efficiently separates wellhead produced oil‑gas‑water mixed fluid into independent crude oil, associated gas and produced water streams, widely applied for single‑well sites, metering stations, transfer stations and combined stations. This equipment works in linkage with Crude Oil Heater and Crude Oil Heat Exchanger to pre‑heat incoming fluid for viscosity reduction, greatly improving oil‑water settling efficiency and lowering water and gas content of crude oil. It can form complete well‑head processing‑storage system together with Single Well Oil Storage Tank, so separated crude oil can flow directly into the tank for temporary storage and tanker transportation. Boasting powerful system expandability, it seamlessly connects Solid‑state Energy Storage Heating Equipment, Multi‑energy Coupled Crude Oil Heating Equipment and New Energy Zero‑carbon Heating Equipment, building an int…
