LNG Production and Storage Facilities
It is estimated that by 2020, gas will supply about 25% of the
global energy demand and with the benefit of being a relatively
clean fuel, this percentage will further increase. As many of the
world gas reserves are geographically isolated from the market,
LNG (Liquified Natural Gas) will play a major role in the efficient
delivery of energy to the end user.
The production of LNG by conversion of natural gas to liquid
is done in a series of processes that are commonly known as
“gas trains”. During these processes the gas is cleaned and dried,
liquefied by cooling to -160°C and stored in large LNG storage
tanks ready for pumping to LNG Tankers.
Foundation Heating for Refrigerated Storage Tanks
LNG is stored in large insulated atmospheric pressure storage tanks. As the LNG is stored at
-160°C, the foundation slab requires heating to prevent frostheave and potential foundation
buckling due to an ice lens formation, resulting in potential destruction of the tank. Other typical cryogenic products that
also require slab heating are Butane and Propane.
Given the critical nature of this application Thermon uses 3D FEA analysis to provide a comprehensive design that includes
edge effects. Heater cable is placed in conduit in the foundation slab providing uniform heat across the tank base and
circumferentially in the ring walls as required. Thermon can also advise on the appropriate control and monitoring system.
Recommended heat tracing system:
FP constant watt heating cable or
RSX self regulating heating cable, both with RTD
Gas Sampling and Instrument Impulse Lines
Process and analytical analysers require the sampling tubing to be heated above the process or dew point of the specific
gas to ensure the sample reaches the analyser at the desired elevated temperature. Pre-insulated heated tubing bundles
include tube, heater cable, thermal insulation and outer jacket as a combined custom product called TubeTrace®. TubeTrace
provides an efficient and cost effective solution to heat trace small OD tubing. Recommended heat tracing system: TubeTrace
with customer specified tubing type and BSX or HTSX self regulating heating cable and thermostat control.
Process Temperature Maintenance
Process and dew point maintenance for a variety of products transferred in pipelines within the plant. Typical products
requiring electric heat tracing are oxazolidone, waste vent gas, buffer gas and gas metering. Recommended heat tracing
system: HTSX self regulating heating cable or if higher maintain temperatures are required HPT power limiting heater cable
or MIQ mineral insulated heater cable.
Electric Heat Tracing Standards and Codes
Thermon heat tracing products are tested and certified by major approval agencies to international industry standards.
