Case Study: An Integrated Calibration Solution That Meets Refinery's Demanding Safety And Regulatory Requirements

Calibration is a very important part of the refinery's control and automation. Until recently calibration was mainly driven by economic motives: even the smallest of errors in delivery quantities are unacceptable in Shell's operation due to the vast sums of money involved for both customers and governments (fiscal metering). Nowadays calibration has an important role especially for the license to operate. Government regulations demand that specific instruments must be calibrated, for example instruments related to CO₂ and NOx emissions. Government regulations require that instruments associated with safety systems are regularly calibrated and the results documented in accordance with the IEC 61511 standard.
