  • Best Practices For Flare QRA Tools

    Flare Quantitative Risk Analysis (QRA) is a systematic approach to determine the adequacy of a flare header and can be applied to provide a more realistic assessment of the risk associated with vessel accumulation due to common mode scenarios, in accordance with American Petroleum Institute (API) Standard 521. The QRA process takes the results of a traditional flare study and adds QRA inputs. These include the frequencies of the common mode scenarios, and the effects of instrumentation, operator intervention, and other layers of protection that tend to reduce the severity of the common mode scenario. The process generates a system risk profile, such as an accumulation versus frequency relationship for each vessel discharging to the relief header, which in turn can provide an estimate of the risk of catastrophic loss of containment associated with the relief header system. Flare QRA may reduce costs associated with the need to retrofit flare headers or construct new ones.

    Experience has shown there are several challenges when performing QRA, including (a) how the system level risk is defined, (b) verification of reliability data used as QRA inputs, and (c) how considering only individual equipment may skew the view of resulting risk. This paper discusses these challenges, as well as what results can be expected from Flare QRA and what issues (e.g., flare tip) are not addressed through this analysis process.

  • Choosing Functional Safety Field Instrumentation

    There is a lot of confusion around Safety Instrumented Systems (SIS) and the associated protection layers. While some may claim that “IEC 61508 certified equipment” is the way to go, others defend the concept of using field data collection and analysis of previously used general purposes instrumentation as the way to select appropriated instruments.

    This white paper addresses the controversy surrounding discussions about determining the equipment to use in safety instrumented systems (SIS) and the rules for maintaining them.

  • eHandbook: Do Your Level Best

    People have been using various devices to measure level since about 3000 BC. The first historical references to a measuring device were dipsticks or staff gauges used to indicate the amount of water stored in reservoirs for farming. Next came crude float-type devices to indicate the height of drinking water reserves in underground cisterns or storage caverns.

    Modern instrumentation uses more than 20 different technologies to satisfy the ever-growing requirements for level measurement in a wide variety of applications. Some instruments measure level directly, while others measure some other variable that is related to level.

    To help you do your level best, Chemical Processing has put together an eHandbook. It includes insight on:

    • Get To The Bottom Of Level Limitations – Positioning the lowest tap for a measurement demands care
    • Consider FMCW Radar For Level Measurement – Technology helps plant continuously monitor inventory in dust-prone environment.
    • 3D Level Sensors Help Address Storage Challenges – Technology and software advances provide greater visibility into a vessel’s inventory.
