Natural gas experiences a temperature drop after passing through the separator
Thread Content
This station is connected upstream to an oil and gas field gathering and distribution station. Since no treatment is carried out at the upstream station, desulfurization and dehydration are necessary at this station. Currently, there are two issues: 1. The temperature of natural gas drops significantly as it moves from the inlet to the desulfurization equipment; the inlet temperature is as low as 5 degrees in winter, but after passing through the filtration separator, the temperature drops by another 5–8 degrees. It’s not clear what causes this 2. Natural gas enters the desulfurization equipment, which lacks insulation as well as heating facilities. Inside the desulfurization equipment (where solid desulfurization is used), the temperature of natural gas drops to -17 to -18 degrees; is the desulfurization efficiency poor in winter? Could everyone please help analyze what the cause is and if there are any good solutions! Thank you! :)
Because pressure reduction and vaporization cause the temperature to drop. One aspect is to check the pressure conditions in various sections; moreover, natural gas contains components that have been liquefied, and this requires control at the upstream stage, or you need to separate them yourselves.
Problems with the filtration separator. Please contact me for further explanation
It is the natural gas that, after being dehydrated using triethylene glycol at the upstream stations (without desulfurization), is sent to the main station. A filtration and separation unit is installed at this main station; after passing through this unit, the temperature of the natural gas drops by 5 to 8 degrees. In winter, when the temperature is 5 degrees, the temperature of the natural gas drops below 0 degrees after passing through the filtration and separation unit. I’m not sure what the reason for this is Please give me some advice.
