What is reason #2 to choose for a vacuum system?

This question 7 is in continuation of question 6 in which we started explaining why an active vacuum leak detection system is superior over an active pressurized system. Active leak detection systems can be either a pressurized system, in which an inert carrier gas stream flows through the leak detection circuits most probably only via the machined leak detection grooves present in the carbon steel and a vacuum system, where one pulls vacuum pressure underneath the liner.

We recommend a vacuum based leak detection system for several reasons:

Reason #2: Direct detection of the complete carbon steel surface

The State-Of-The-Art Ammonia Terminal

Since 100 years ago the industrial production of ammonia began for the widespread agricultural and industrial application. Safety hazards and risks have been identiﬁed and for a large extend resolved.

Nowadays ammonia is used more and more as a very eﬃcient hydrogen energy storage, carrier and carbon free fuel. This means that more and more people will get involved with this potentially toxic substance. How will the public and the authorities react?

Are the previously known safety regulations suﬃcient for the storage / bunkering of ammonia?

We say no, it can be better, more safe and reliable.

What is reason #1 to choose for a vacuum system?

We recommend a vacuum based leak detection system for several reasons:

Reason #1: No risk of liner bulging

A first reason is that when using a vacuum system there will be no risk for liner bulging and damage due a to too high pressure in the leak detection system behind the liner. Be aware that the relatively large liner compartments are welded to the carbon steel pressure bearing wall. These large areas allow only a very limited pressure difference between each side of the liner.

Some vendors try to avoid this risk of bulging by switching off the leak detection system when the pressure in the synthesis section is below a certain value. In our view this is not a good solution because...

Which kind of active leak detection systems exist ?

High pressure urea equipment consist of a heavy carbon steel pressure bearing wall, which is protected against corrosion by a thin corrosion resistant layer; this layer is in the most cases made out of stainless steel or a duplex. This protective layer can be an overlay welding, an explosive cladded layer but is in most cases a loose liner.

Any leak in a loose liner will lead to a dangerous situation because a potentially corrosive fluid can be spread and trapped in the gap between the carbon steel pressure bearing wall and the loose liner. This area will then be exposed to the extremely corrosive ammonium-carbamate.

Real situations have proven that ammonium-carbamate can corrode carbon steels with very high corrosion rates up to 1,000 mm (40 inch) per year. But also stainless steels will show accelerated corrosion because of lack of oxygen. That means that it is an absolute must to have a detection system present that already warns for al leak in an early stage. Then one can only conclude that an active leak detection system is required...

Why flushing with steam or condensate is NOT a good practice ?

To check if a leak detection system is not facing any clogging or to unclog a leak detection system, some plants practice a flushing procedure with steam or water.

This is not recommended and even dangerous! Introducing water can lead to corrosion. Corrosion, as known, is an electrochemical reaction so corrosion can only take place when water is present.

Without water no corrosion.

The corrosion product will block the passage ways and can also block the leak detection holes.

A more threatening form of corrosion that can occur is stress corrosion cracking of the carbon steel pressure vessel wall.

UreaKnowHow.com will present at CRU's Nitrogen+Syngas 2021 Virtual Conference

For 33 years, CRU's Nitrogen + Syngas conference has provided an annual platform for the global industry to meet, network, and learn. Every year, 740+ producers, licensors, and materials and equipment providers attend to ensure they have knowledge, understanding and professional connections required to improve their production, maximise profitability, and maintain safe, reliable, and environmentally responsible operations.
In 2021, due to the pandemic, Nitrogen + Syngas will go ahead - as a virtual event. The tried and tested virtual platform allow CRU to deliver an interactive environment for all participants to meet, learn and network. The only virtual element of the conference is the venue - the conference still offers real insight, real networking, and real business opportunities.
UreaKnowHow.com will present a paper with the title: How to Improve Safety and Reliability of the High Pressure Synthesis Section of Urea Plants. The paper draws conclusions from a detailed analysis of the more than 130 serious incidents of the UreaKnowHow.com Urea Incident Database.

In Memoriam Jan van der Werf

Jan van der Werf died peacefully Monday morning November 30, 2020 at an age of 76 in his hometown Sittard-Geleen.

With a career of 55 years at Stamicarbon, Jan was enjoying his work with whole his heart. Jan did know where he was talking about, he knew what was urea as he was involved in numerous commissioning and start-up projects. Jan started up one of the first CO2 stripping plants under difficult circumstances in the former DDR, the first PoolCondenser plant in Bangladesh and left his footprint in many other countries like North Korea, Thailand, Romania, USSR, Japan, USA, Myanmar, China, Mexico and Alaska. Jan also worked at several high level management positions in Stamicarbon, always pushing forward innovations and breakthroughs in our industry; amongst many others Safurex^® and Full Life Cycle support.

Everywhere we came, people asked how Jan was doing. Jan was open, friendly, flexible and always in a good mood, Jan was really a great manager and colleague, with both feet on the ground, one between his colleagues, his door was always open, Jan was always striving for cooperation and teambuilding. We and we believe many other colleagues owe Jan a lot. Jan was always in to discuss technical issues, strategical topics and life in general, preferably with a pint of beer.

Jan, we will miss you.

We send condolences to Wilma, Guido and Petra and the entire van der Werf family.

Why is a passive leak detection system not acceptable anymore?

In a passive leak detection system an indication of a leak in the liner only shows up when the leak emerges from the leak detection hole. Or, in case the leak detection hole is connected via tubing to for example a bottle with a phenolphthalein solution, when the colour of the liquid in the bottle changes. The detection occurs at a later moment then when the leak occurs in the liner. Time passes (dwell time) between the moment the leak occurred and the moment the leak emerges at the leak detector or when a field operator notifies the leak. The latter case is even worse as the dwell time can be much larger. During that dwell time the risk that the leak detection path gets clogged is realistic. That means that there will be a serious threat to the integrity of the carbon steel pressure bearing wall... Click here to Read more.

UreaKnowHow.com prepares a Risk Register Leak Detection System for Loose Liners of High Pressure Equipment

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?
