AMMO LASER Leak Detection System
The #1 Safeguard with a Guaranteed Pay Back Time
- Our design is based on detailed safety hazards studies and analysis of industry incidents.
- Is able to distinguish false indication from an ammonia cloud in the atmosphere from a real liner leak. In fact, this means it warns the operator for another leak in the urea synthesis section and proper actions can be taken.
- Gives leak rate and calculates leak size.
- Includes a continuous detection for the presence of any liquid.
- Allows safe and simple introduction of leak detection tracer for pinpointing the leak.
- The only and safe alternative for flushing with water behind the liner.
- We can offer a Guaranteed Pay-Back Time of less than 3 years.
- More than 6 references since 2017.
- Approved by SAIPEM.
The AMMO LASER Leak Detection System has the following features:
Highest Reliability
Most widely applicable
Most economical solution
Suitable for other safeguards and emission reduction
Highest Reliability
- Most reliable system as proven by the Risk Register Leak Detection Systems)
- Monitors directly, continuously and accurately the complete liner surface under all operating conditions
- Continuously informs the DCS operator about the vacuum pressure and ammonia content level
- Is able to distinguish false indication from an ammonia cloud in the atmosphere from a real liner leak. In fact this means it warns the operator for another leak in the urea synthesis section and proper actions can be taken
- Introduces no risks for liner bulging and rupture
- Works also when the synthesis pressure is low and when the liner sees most stresses (heating up, cooling down) and hence a leak detection system is important
- Does not restrict the leaking flow and does not built up pressure or introduce risks for backflow (refer to Incident 19-005)
- Is able to dilute the leak and hence minimize the risk of blockages
- No need anymore to flush with steam or condensate
- SAIPEM, as owner and licensor of the Snamprogetti™ Urea Technology, approves the AMMO LASER Leak Detection System for application in all its plants
Most widely applicable
- Enables leak detection also in case the grooves are blocked caused by solids from an earlier leak
- Enables leak detection also in case the grooves are blocked caused by corrosion of carbon steel caused by an earlier leak or due to flushing with steam or condensate
- Enables leak detection also in case only one leak detection hole is present
- Enables leak detection in case of bad design/fabrication of grooves
- Enables leak detection in case of no grooves present
- Enables leak detection in case there are connections between different leak detection compartments
Most economical solution
- Requires tracing and insulation of only a part of the tubing
- Can combine one ammonia analyzer for multiple equipment items (even from more urea lines)
- The AMMO LASER ammonia analyzer is the most accurate and reliable ammonia analyzer as it provides a DCS alarm in case out of order, is ammonia specific and is self-calibrating
- Requires no inert gas supply and only a low power consumption
- A Guaranteed Pay Back Time resulting from shorter shut down periods as one can find the leak faster, knows the leak size and is able to assure no damage to carbon steel pressure bearing wall
- Plus a Guaranteed Pay Back Time resulting from lower NH3 consumption figures
Suitable for other safeguards and emission reduction
- The AMMO LASER ammonia analyzer can be combined with up to seven other safeguarding and NH3 emission sources monitoring leading to lower ammonia consumption costs
