Clogging in the leak detection system is by far the most serious risk to cause high corrosion rates of the carbon steel pressure bearing wall of high pressure urea equipment. A state of the art leak detection system should safeguard first and for all warn before clogging occurs. Key words to avoid the aforementioned situations are early detection and high reliability.
This is the reason that passive leak detection systems, where one waits for the leak to show up at the analyzer are unsafe and not acceptable anymore today. This has been proven through trial and error in numerous incidents, for example Urea Incident 18-005 (FIORDA Urea Case #5).
The next question is: What are the requirements for a state of the art active and reliable leak detection system?

After establishing the largest Urea Incident Database with 130+ incidents, now UreaKnowHow.com starts up a UAN Incident Database. UAN seems a safe, non hazardous, colourless liquid but several serious hazards and risks are to considered when designing, operating and maintaining UAN plants. Experience has proven that HAZOPs only do not provide sufficient assurance that all risks are properly take care (background reference). Learning lessons from earlier incidents is in our opinion a very effective way to increase safety and reliability of your plant. Click here to go to our UAN Incident Database

Urea incident databases and risk registers clearly prove the need for a proper leak detection system for loose liners of high-pressure urea equipment as the #1 Safeguard for Any Urea Plant. UreaKnowHow.com and KeyTech Engineering Company have developed an active vacuum-based leak detection system with the most accurate and reliable ammonia analyzer: The AMMO LASER Leak Detection System. This leak detection system is the most reliable leak detection system over all existing leak detection systems in operation so far.

High Temperature Hydrogen Attack (HTHA) is a problem which concerns steels operating at elevated temperatures in hydrogen environments. It is not to be confused with hydrogen embrittlement or other forms of low temperature hydrogen damage. HTHA is a time-temperature-pressure function. These, basically means the longer that a piece of equipment is exposed to temperatures above its resistance limit in certain hydro-process environment (see API941-NELSON Curve), the more damage to the steel will accumulate; and the higher the temperature rises above the limit of the steel, the more rapidly the damage will occur. Monitoring the integrity of equipment in HTHA-Service is necessary to avoid accidents, especially if one of the following reasons are true: - HTHA in many old plants -is true for many ammonia plants- can occur especially after a long onstream-time, if the incubation time ended. - However, there have been several cases where HTHA was found, even though operating conditions were below the Nelson Curve. - There are new findings since 2016: After explosion in the TESORO refinery with 7 dead, it must be assumed that HTHA in C steel can already be expected at > 204 °C and a hydrogen partial pressure of pH2 > 3.45 bar. It is strongly recommended to monitor the integrity of HTHA vulnerable equipment! Due to the age of many ammonia plants, a lot of equipment may need to be replaced. For avoiding HTHA of new equipment, use the recommendations for fabrication of new equipment in the hydrogen service according API 941 and API 934A! Click here for more information

VECOM are Global Expert in Chemical Cleaning.
In urea plants for example VECOM are the experts in cleaning of the Urea Stripper and Recirculation Heater.
The Vecom way - in practice: Our core value is: safe for people, the environment and metal. Our industrial customers benefit from more than 65 years of leading experience in metal surface treatment and can feel 100% assured of the correct treatment of their process installations. Clients of our customers often indicate that they would like to have their products and installations treated "The Vecom way". The highest quality guaranteed for surface treatment The Vecom way also means that procedures have been laid down for our customers. This guarantees equal results with the same metal contamination. When a new procedure is required, it is tailor-made. Research into the metal alloy is done through a Metal Analyzer and into the contamination is done in the in-house laboratory of Vecom.
