(1)Features
Pressurized barrier system (closed circuit)
for use in seal systems with high pressures
and/or for hazardous/environmentally
harmful processes. The SPO (Plan 53B)
range is available with a pressure
accumulator, cooler (finned tube, water or
air cooler with fan) and a wide range of
instruments.
Circulation in accordance with API 682/
ISO 21 049: Plan 53B
(2)Advantages
• Pressurization is by means of a pre-loaded bladder accumulator
• The nitrogen is separated from the barrier medium by membranes in the accumulator:
nitrogen cannot get into the barrier medium or process medium
• Barrier pressure is created without any need for connection to a nitrogen supply
• Available with finned tube, water or air coolers with fan
• Modular system: combination with a wide range of system components/instruments possible
(3)Functional description
The SPO is designed to perform the
following functions of a barrier system:
• to pressurize the buffer chamber
• leakage compensation
• to cool the seal
Pressurization (> process pressure)
prevents the process medium from getting
into the barrier circuit or the atmosphere.
Pressurization is supplied by a pressure
accumulator which is pre-loaded with
nitrogen. Circulation in the barrier circuit
takes place by the thermosiphon principle
or by forced circulation, e.g. with a
pumping screw.
(4)Standards and approvals
• PED 97/23 EC (Design and production in accordance with EU Pressure Equipment Directive)
• ASME VIII, Div. 1 (Design, calculation and production)
(5)Recommended applications
• Petrochemical industry
• Chemical industry
• Oil and gas industry
• Refining technology
(6)Notes
A refilling unit has to be provided.
