Steam boosting

Turbovaps can custom‑manufacture steam‑boosting compressors to meet specific customer requirements. To date, it has a proven track record across a wide range of applications, with inlet pressures as low as 6 kPa absolute (corresponding to saturated water vapor at 37°C) and outlet pressures up to 1,500 kPa absolute (saturated water vapor at 200°C). These units are ideally suited for situations where plant steam supply pressure is insufficient or when low‑pressure by‑product steam cannot be utilized. Typically, for every doubling of steam pressure (absolute), power consumption increases by approximately 40 kWh; in most operating conditions, the investment can be recouped relatively quickly.

Steam pressure boosting in the pipeline network

In industrial production, when the required steam pressure is insufficient, a centrifugal steam compressor can be used to boost the steam pressure, thereby avoiding the many complications associated with rerouting high-pressure pipelines. This not only helps users reduce capital‑expenditure costs but also allows for flexible adjustment of the compressor’s flow rate and discharge pressure, minimizing fluctuations in the piping network and facilitating adjustments to the user’s production load.

At present, the multi-stage centrifugal steam compressors manufactured by Turbovap have already been successfully deployed in numerous applications, such as:

1) Successful application cases where the outlet pressure reached 1.8 MPa;

2) A successful application case of a turbocharger with a minimum starting pressure as low as 5 kPa absolute (vacuum: -0.95 bar);

3) Successful application cases with inlet volumetric flow rates as low as 1,500 m³/h (less than 1 t/h at atmospheric pressure), where the rotational speed can reach 40,000 to 50,000 RPM;

4) A successful case featuring up to 9-stage cascaded compression, achieving a total compression ratio of 140;

5) Case studies demonstrating the successful implementation of a CCS control system, featuring millisecond response times, precise surge prediction, and proactive intervention.

Typically, for every doubling of steam pressure (absolute), energy consumption increases by approximately 40 kWh; in most operating conditions, the investment can be recouped relatively quickly.

Recovery of waste heat from hot water

Condensate generated in various production processes can have its thermal energy recovered. By means of multi‑stage flash evaporation, low‑pressure saturated steam at different pressures is produced; this steam is then compressed to higher pressure using a multi‑stage De Ville turbine compressor, yielding high‑quality steam suitable for use.

Dewitt Turbines can supply single‑stage flash‑steam boosting compressors with flow rates ranging from 1 to 200 tonnes per hour. Typically, an additional compression stage is added whenever the required temperature rise exceeds 20°C. Dewitt Turbines currently boasts proven operational experience with single‑unit four‑stage compressors and offers a broader range of options to meet diverse customer requirements.

Typically, after implementing this unit, the payback period does not exceed two years; for units with a flow rate exceeding 5 tons per hour, the payback period may be less than one year. Moreover, this compression method effectively addresses issues such as water hammer in condensate‑system piping and the high energy consumption of air coolers.

Application scenarios

In sectors where low‑ and medium‑temperature waste heat—such as low‑pressure steam, exhaust steam, and condensate—is widely available, including the chemical, petroleum, steel, power, pharmaceutical, textile, and paper industries, high‑temperature, high‑pressure water‑steam centrifugal compressors can be employed to boost the pressure and temperature of low‑pressure steam and flash‑evaporated steam. This upgrades the thermal energy quality, enabling its reuse and delivering substantial energy‑saving and carbon‑reduction benefits.
