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.
