Method for removing large amounts of condensate from an underground vault steam system during startup

A method for removing condensate from a steam line during a cold startup, comprising:

• introducing a dip tube in a substantially vertical orientation within a substantially vertical section of a steam line during a cold startup of the steam line, wherein the dip tube comprises a proximal end and a distil end,
• immersing the distil end within a volume of condensate located within the steam line, wherein the steam line is at a first pressure,
• connecting the proximal end to a removal conduit external to the steam line, wherein the removal conduit is at a second pressure, and wherein the first pressure is greater than the second pressure, and
• removing at least a portion of the condensate through the removal conduit due to the pressure difference between the first pressure and the second pressure, wherein:
• the substantially vertical section of a steam line comprises an anterior interior surface,
• the dip tube comprises a second centerline, and
• the second centerline and the anterior interior surface are separated by a second predetermined distance.

• a substantially horizontal section of the steam line upstream of the substantially vertical section of the steam line,
• a first piping elbow located between the substantially horizontal section and the substantially vertical section,
• wherein:
• the first piping elbow comprises a major interior radius,
• the dip tube comprises posterior side and a distil end,
• a line extending from the dip tube posterior side and the intersecting with the major interior radius comprises a piping tangent, and
• the distil end of the dip tube and the piping tangent are separated by a third predetermined distance.
