Philip Morris Bologna: SPH two-stage heat pump supplies dryer steam at 139°C
SPH / JOA demo card (installation year 2025): at Philip Morris Manufacturing & Technology Bologna, a two-stage heat pump turns dryer exhaust heat into saturated steam at 139°C and 2.5 bar(g). Rated duty is 650 kW. A FAT COP of 2.5 is source-reported, not remeasured here.

- Industry
- Drying
- Source temperature
- 36–50°C

- 90–139°C
- Temperature lift
- ≈ 40 K
- Heating or cooling duty
- 650 kW
- Architecture
- Two-stage reciprocating heat pump (SPH) integrated by JOA with direct recovery from humid dryer exhaust
- Result status
- The card lists installation year 2025, about 5,000 h/a, and a COP of 2.5 measured during factory acceptance testing. That FAT figure is not a published multi-season site audit.
- Key risk
- Working fluids are R515B and R1233zd, not natural refrigerants. The 650 kW rating is a dryer module, not a large boiler replacement.
- Existing system
- Industrial dryer with humid exhaust; process steam previously supplied from the site boiler plant
- Refrigerant
- R515B and R1233zd (two stages)
- COP
- 2.5
- Annual savings
- Card: about 3.9 GWh/a heat delivery and about 1.7 kt/a CO₂; more than half of the dryer heat demand reported as covered by recovered energy
- Estimated payback
- Not disclosed; the card leaves investment and cost savings blank
项目背景
Philip Morris Manufacturing & Technology Bologna published, via SPH and JOA, a dryer heat-recovery package that makes its own steam. The industry tag on this site is drying, so it can be filtered separately from food cooking and from paper-mill steam.
叙述性输入
Source water 50°C → 36°C after exhaust recovery. Sink 90°C → 139°C saturated steam at 2.5 bar(g). Heating capacity 650 kW. Design operating time about 5,000 h/a.
热泵方案
Humid exhaust is recovered directly, then a two-stage heat pump lifts the residual heat, first toward 80°C and then to 139°C steam that returns to the dryer. Compressors are reciprocating. The integrator is JOA Air Solutions; the heat pump supplier is SPH.
COP 与节能
COP 2.5 is explicitly a factory-acceptance measurement on the card, at the design point above. Annual heat delivery is given as about 3.9 GWh and CO₂ savings as about 1.7 kt/a. Investment is blank.
投资回报要点
No investment or payback is published on the card used here.
