Safety systems specialist Hima-Sella has received an order for end-of-life replacement of SIS (safety instrumented systems) on two processing units at the Petroplus' Coryton Refinery in Stanford-le-Hope Essex.
 Petroplus is replacing SIS equipment that protects its naphtha hydrotreating and continuous catalytic reformer processing units, and the new system will use two Hima HiQuad H51q-HS programmable electronic systems (PES), designed to meet IEC61508 SIL2.
HiQuad systems are already in use at Coryton, protecting the site's cracking complex and bitumen road loading facilities, which enable Petroplus to consolidate onsite spares and reduce maintenance costs.
Eddy Turnock, Hima-Sella's sales and marketing director, explains that the new HiQuad systems will be supplied with tiled matrices for indicating local unit conditions, such as start-up overrides, output conditions, emergency shutdowns and a variety of site-wide general alarms.
