Natural gas heaters
Sandvik electric natural gas heaters are used to heat natural gas in pressure reduction stations or systems in Liquefied Natural Gas (LNG) stations, fuel forwarding plants, and natural gas import and export stations. Read more about natural gas pressure reduction.
Electric natural gas heaters are generally used as super heaters to heat gas before or after the pressure reduction valve. They range from very large (several MW) in large-scale gas transport for industrial plants to very small (a few kW) for instrument heating. If the heating requirements are high more than one heater can be used in series or parallel arrangements.
Materials of construction
In Sandvik natural gas heaters, the elements and internals are constructed of alloy 800, and the vessel and tubesheet are of stainless steel of the types ASTM 321H, 316Ti or alloy 800.
Temperature and capacity range
Sandvik electric natural gas heaters have an operating temperature range of 0°–200°C (32°– 392°F).
Available in capacities from 1–10000 kW, Sandvik electric process heaters have smaller footprints. They are virtually 100% efficient and there is no risk of fouling that creates a need for frequent cleaning.
