Abstract： In response to the problems of scaling in circulating water of a 28 000Nm3⋅h-1 oxygen generator unit and excesiveexhausttemperatureofanitrogencompresor，aphosphorus-freecompositescaleandcorosioninhibitorLGHB-ZH-01 （PASP/HPMA/AA-AMPS-HPA） was developed. At 80°C and 50mg⋅L-1 it achieved 73.65% scale inhibition and 0.0294mm⋅a-1 carbon-steelcorosion.Equippdwithautomaticdosing，uniformwaterreplenishmentandchemicalcleaning，thesystem concentration multiple is stableat 3.4±0.1 ，cutting compressor outlet temperature to $＼leqslant 4 0 ＼ ＼mathrm { ～ ＼textleqslant ～ }$ ，saving 31% water and 47 % chemicalsannuallandenabling12monthsofunplanned-shutdown-freeoperation.Thestudydemonstratesapracticalroutefor phosphorus-free，low-consumption and long-term stable operation of high-temperature circulating water systems.
