Vacuum distillation initial vapor overhead separation tank
Thread Content
May I ask why the atmospheric and vacuum initial overhead oil-gas separation tank as well as the atmospheric overhead separation tank need to be insulated? Weren’t we supposed to cool it down earlier?
It is at a high height above the ground, so there is no risk of scalding people

According to the \"Design Code for Insulation of Petrochemical Equipment and Piping\" (SH/T 3010-2013), section 5.4, for uninsulated equipment and piping that require regular maintenance and for which no other measures can be taken to prevent burns, insulation to protect against burns should be installed within the following ranges when the surface temperature exceeds 60°C: a) a height of less than 2.1 m from the ground or operating platform; b) a distance of less than 0.75 m from the operating platform. The initial gas oil separation tank and the normal pressure gas oil separation tank are usually installed on the platform, at a height not too great above the operating platform; therefore, heat protection measures are necessary to prevent burns.
1. Heat protection and insulation 2. Maintaining an appropriate delivery temperature
Insulation is not necessary, but if the medium temperature exceeds 60 degrees, heat protection insulation should be used
Everything said earlier is correct; another possibility is that the package was packed incorrectly. This has happened in our company as well, and fortunately it led to an explosion being averted.
They are two different things: cooling is used to change gas into liquid, while insulation is used to prevent condensation and freezing in winter
