Pipeline heat tracing issues
Thread Content
After passing through the throttle valve, natural gas experiences a decrease in pressure; as a result, the gas expands and its temperature drops. How should the heat carried along the pipeline be calculated? Please offer your guidance
First, take a look at the specific data on the temperature drop; based on that data, calculations for heat tracing can be carried out, using formulas related to heat transfer. For reference only.
Calculate using the heat transfer formula, as your heat tracing tube will be placed alongside the main pipe, and there is also insulation for heat retention and prevention.
I’ve never worked with natural gas, so I can’t help the original poster, but I do have a question: by how much does the pressure of the gas need to be reduced, and will the temperature drop significantly after expansion?
