Protecting compressors under challenging circumstances
The use of dry gas seals on large
operating equipment such as turbo
compressors has increased significantly
over a number of decades particularly in
harsh working environments such as oil
& gas, petrochemical and gas processing
industries. A dry gas seal uses a clean gas
under pressure on the external side of the
seal, so that any leakage through the seal
is the buffer gas into the compressor. Not
only does this protect the environment
from being contaminated with process gas,
but it keeps dirty gas from getting inside
the seal and causing damage.
An important component of a dry gas seal
is the vent system. For the primary vent
system, a rupture disc is typically installed
in parallel with the vent line to rupture
at a set pressure and prevent excessive
pressure to instruments on a primary seal
failure. A signalling system, on the primary
vent system is recommended to enable

integrity checks while the seal system is
still online.
Customer’s using dry gas seals require
rupture discs to be installed to vent excess
pressure in the event a catastrophic
failure of the primary seal occurs. In the
event the pressure increases beyond
its predetermined limit a higher gas flow
or back pressure in the piping system is
present and needs to be safely vented. A
signalling device is also required to detect
a change in the rupture discs status in order
to initiate a shutdown of the process in the
event of an overpressure situation.
REMBE’s reverse acting rupture disc
with an integrated polyamide signalling
device (SGKIKB) is a cost-effective rupture
disc which is suitable for the demanding
conditions found in dry gas seal applications.
Used extensively in downstream projects,
the IKB is the only reverse acting rupture
disc to be manufactured using REMBE’s
unique Contour Precision Lasering (CPL)
technology ensuring high quality, accurate,
burst control even in the harshest of
environments.
