Flare Selection for the Chemical Process Industries
By Anu D. Vij, Ship & Shore Environmental |
There are many factors to consider when selecting a flare system for CPI sites that can impact safety, operating costs and environmental performance
Flaring has long proven to be an effective technology for disposing of gases that cannot be used otherwise. Different flaring techniques are utilized in the chemical process industries (CPI), depending on environmental regulations, site requirements and process needs. Different flare technologies offer tradeoffs among equipment cost, operating expense, design complexity and process requirements. Selecting the proper flare equipment can result in optimized capital and operational costs while maintaining compliance with environmental requirements. Before a flare type is selected, it is important to understand the environmental impacts, process requirements and economic considerations of a particular operation or project. Improper application of a flare technology can lead to not only poor performance, but also negative environmental impacts, which can later result in significant costs and legal implications. This article provides details of the different types of flares used at CPI sites and their selection criteria.
