Safety instrumented systems

Safety systems specialist Hima-Sella
has received an order for the end-oflife
replacement of Safety
Instrumented Systems (SIS) within
two processing units at Petroplus’
Coryton Refinery in Stanford-le-
Hope in Essex, England. The facility
is a fluid catalytic cracking refinery
with a throughput capacity of
220,000 barrels per day.

Petroplus is currently replacing SIS
equipment that protects the Naphtha
Hydrotreating and Continuous
Catalytic Reformer processing units.
The SIS is to be implemented using
two HIMA HiQuad H51q-HS
Programmable Electronic Systems
(PES), designed to meet IEC61508
SIL2, and will be located in a local
instrument house. In addition,
HiQuad systems are already in use at
Coryton, protecting the site’s
Cracking Complex and Bitumen
Road Loading Facilities, which
enables Petroplus to consolidate
spares and reduce maintenance costs.
