SIS-TECH

The SIS-TECH Coker Drum Safety System (CDSS) automatically inhibits the opening of valves under unsafe process conditions. In a crude oil refinery, this prevents the release of hydrocarbons and/or hydrogen sulfide to the atmosphere, or introduction of hydrocarbons to an open drum. The CDSS logic solver makes sure that an in-service drum is not opened to the atmosphere, or that an open drum is not placed in service.

SIS-TECH announces the Automated Overfill Protection System (AOPS), a safety instrumented system (SIS) that can prevent dangerous overfill conditions in terminals, tank farms and process vessels.

SIS-TECH announces the DIAMOND-SIS High Integrity Protective System, a low-cost standalone logic solver certified for use in applications up to Safety Integrity Level (SIL) 3. The DIAMOND-SIS HIPS is used to provide overpressure protection for scenarios where the opening of the pressure relief valve poses unacceptable process safety risks.
