The Circulating Water and Steam Heating Vaporizer offers dual-mode operation for cryogenic liquid vaporization, utilizing either hot water (60–90°C) or saturated steam (150–200°C) as thermal energy sources. Engineered for high-flow industrial applications (10,000–50,000 Nm³/h), these vaporizers achieve 95% thermal efficiency with minimal pressure drop (≤0.5 bar), making them ideal for processes requiring flexible heat input .
Water Heating Mode:
A closed-loop circulation system (powered by Grundfos CR series pumps) maintains water temperature within ±2°C, using glycol-water mixtures (50:50 ratio) for freeze protection.
Stainless steel shell-and-tube heat exchangers (with 100–500 tubes per bundle) maximize surface area, ensuring efficient heat transfer to cryogenic fluids.
Steam Heating Mode:
Saturated steam at 0.5–2.0 MPa (151–194°C) flows through jacketed coils, providing rapid heat input for peak demand scenarios (e.g., sudden production spikes).
Spirax Sarco automatic condensate recovery systems capture and reuse 80% of condensed steam, reducing water consumption by 30% and lowering utility costs .
High Thermal Flexibility
Multi-circuit design allows simultaneous operation of water and steam loops, accommodating variable load requirements (e.g., 50–100% capacity modulation).
ABB ACS880 VFD-controlled pumps adjust water flow rates (10–100 m³/h) in real time, matching heat input to vaporization demand .
Corrosion Resistance and Safety
316L stainless steel construction (including tube sheets and shell) withstands aggressive fluids like ammonia, chlorine, and sour gas (H₂S-containing streams).
Dual-pressure relief valves (ASME Section VIII certified) set at 1.2× working pressure prevent over-pressurization, with manual bypass valves for maintenance safety .
Energy-Efficient Operation
Plate heat exchangers recover waste heat from steam condensate (50–80°C), pre-heating incoming water to reduce fuel consumption by 15%.
50 mm mineral wool insulation (with aluminum foil vapor barriers) wraps the exchanger shell, reducing heat loss by 90% and preventing condensation .
Chemical Plants: 20,000 Nm³/h units vaporize liquid ethylene (stored at -104°C) for polyethylene production, maintaining outlet pressure at 30–40 bar.
Food & Beverage: 5,000 Nm³/h units with FDA-compliant gaskets (EPDM) vaporize nitrogen for modified atmosphere packaging (MAP) of fresh produce, ensuring 99.99% purity.
Power Generation: 50,000 Nm³/h units with ASME BPVC Section VIII certification vaporize LNG for gas turbines, delivering natural gas at 25–35 bar to support 500+ MW power output.
Q: How does water heating compare to steam heating in terms of efficiency?
A: Water heating achieves 20% higher energy efficiency for low-temperature applications (<100°C) due to lower heat loss, while steam heating offers faster response times (≤5 minutes to reach full capacity) for high-demand scenarios .
Q: Can these vaporizers handle sub-zero water temperatures?
A: Yes. Models using 50% ethylene glycol mixtures maintain fluidity at -40°C, with integrated heaters preventing freeze-up during cold starts in polar or high-altitude regions .
Q: What maintenance is required?
A: Annual citric acid descaling removes mineral deposits from heat exchanger tubes, while mechanical seal replacement (every 2–3 years) on circulation pumps prevents leaks. Pressure relief valves require calibration every 12 months to ensure compliance .
