How to Manage Leaks in Urea Plants

In 2017, AmmoniaKnowHow.com and UreaKnowHow.com introduced FIORDA, the Fertilizer Industry Operational Risk Database, a global open source risk registers for ammonia and urea plants. On January 1, 2018, the Risk Register Safety Risks in Urea Plants contained its first 100 safety risks. A surprising conclusion from this Risk Register is that most safety risks may lead to a sudden leak releasing a cloud of toxic ammonia. Early detection of a leak is therefore important as a small leak can be more easily contained and clogging can be avoided.

But what to do when there is a leak ?

Can one retighten a flange connection, install a clamp or does one need to stop the plant immediately ?

This Revamp Guide discusses why in urea plants leaks easily occur, what happens when there is a leak, what are the consequences of this, what are critical leaks and what are the prevention and mitigation measures?
