A system and process for extending turndown in a gas-liquid separator is presented. The system includes a first mist extractor with a first operating range and a second mist extractor with a second operating range. The mist extractors are generally of the same type, with the second operating range being different than the first operating range. A gas stream containing entrained liquid droplets flows through the first mist extractor and then through the second mist extractor. Each mist extractor coalesces and captures the liquid droplets within its own operating range, expanding the overall operating range of the separator. Additional mist extractors may be added to cover any gap between the first and second operating ranges.
