Safety systems for cracker complex
August 1st 2010 A total of 1600 safety interlocking
devices from Dutch industrial safety
specialist Netherlocks have been
installed at the Shell Eastern
Petroleum Ethylene Cracker
Complex in Pular Ular, Singapore.
The main applications for the
interlocks are for the decoking
process, and on isolation valves for
PSVs (Pressure Safety Valves).
The interlocks use a linear key
transfer system to ensure that
processes can only be carried out in
the correct order, ensuring each part
has been safely completed before the
next can be started.
Completing the previous step in
the process sequence will release a unique key that unlocks the next
step; only when a mistake is made
will the operator be prevented from
proceeding by a key that does not fit
or a valve locked in position. More articles from Netherlocks BV: |
