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.06/13/2019

Combustible dust fire and explosion hazards continue to challenge process safety practices throughout industries that store, handle or use combustible particulate solids.
To help realize sound ideas and solutions to eliminate fire and explosion threats from combustible dusts, Chemical Processing has put together an eHandbook. It includes insight on:
- Take Key Steps Against Combustible Dust Hazards -- Having a sound mechanical integrity program in place is crucial.
- Defuse Dust Dangers -- Carefully consider and then counter risks of fire and explosion.
- Prevent Dust Explosions With Pressurization Systems -- Technology provides safe, economical option for installing electrical equipment in a hazardous location.
The need for process safety in the chemical industry is paramount. Technical knowledge and understanding of hazards and risks associated with operations in addition to the implementation of that knowledge into practice are the keys to keeping workers and the environment safe.
To help optimize process safety, Chemical Processing has put together an eHandbook. It includes insight on:
- Successfully Reduce Process Safety Events – Other companies can emulate the approach proven effective for Dow.
- Tackle Combustible Dust Safety Challenges – Indoor collection systems and proper venting help extinguish flames and contain extra-fine particulates.
- Use Asset Management Software To Improve EH&S Programs – Ability to capture events and link documents improves environmental, health and safety efforts.
Process Safety is not just an action or legal requirement, but a way of life and an inbred culture. In order for it to work effectively, many actions have to be performed and incorporated into a manufacturing process from conception to decommission. Most importantly it is a live process whereby when any change occurs, no matter how small, the affected operation must be reassessed to ensure that the safety of the process is not compromised.04/25/2018
When properly used, the hazardous area classification system makes for a safer work environment. Too often, however, hazard classes are specified without concern for the significantly higher design and procurement costs they bring. In many cases, an open mind and a little ingenuity can avoid excessive costs for compressors and other equipment, without compromising safety.
This white paper explains hazardous classification systems commonly used in the chemical industry and outlines considerations for installing compressed air equipment in these areas.03/07/2018
Being pretty good at safety may not be good enough for very long. Indeed, the practice of safety in the chemical industry has changed and matured significantly over the past several decades and will continue to evolve. Astute leaders will develop future-centered safety strategies. For the less astute, the future always will be a dark journey full of unpleasant and potentially fatal surprises. Fear of fines and jail time shouldn’t be the motivation for “doing the right thing.”
To offer the best process safety pointers, we’ve put together another Chemical Processing eHandbook. It includes insight on:

- PSM Demands Better Maintenance Planning -- Follow some pointers to succeed at sites covered by the statute
- Mitigate Explosions in Spray Drying System -- Available mitigation approaches depend on the spray dryer system and design limitations
Powders and solids are a tricky business. You have to be proactive to ensure catastrophic events like dust explosions don’t happen. You have to be able to convert laboratory findings into a meaningful process design all while taking into account forces unknown or unseen. And you have to make it all flow according to plan and specs.

Process design and process safety are critical considerations in chemical production and processing. With design and safety paramount at the outset of any new development or equipment retrofit, firms can minimize risk exposure, maximize productivity and position themselves to remain compliant and competitive. Whether retrofit or new, chemical processing is continually challenged by combustible dust. Combustible dust can pose a hidden hazard when accumulation occurs in unseen locations such as in mechanical spaces, above false ceiling, ventilation systems and dust collection systems. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for mitigating combustible dust hazards including:
