Inspection Services Making sure your equipment and piping are safe, reliable and always available The Challenge Although urea equipment is designed for a long lifetime of 20 years on average, the lifetime of a specific vessel is determined by its corrosion resistance. Carbamate corrosion can compromise the integrity of equipment and piping, and it can lead to a catastrophic failure in the plant if regular inspections and maintenance do not occur. Reliable and durable equipment and piping are essential to …

High-pressure Piping Inspection The lifetime assessment of piping for plant safety The Challenge Statistically, failures of high-pressure (HP) piping in chemical plants are more likely to occur compared to failures of HP equipment. This is caused by more frequent periodic or condition-based equipment inspections than piping inspections due to the challenges related to executing the latter. There are kilometers of piping spread across a plant, which can be difficult to access or hard to visually inspect …

Urea Reactor Achieve superior urea reactor lifetime with Safurex® steels The Challenge Urea Reactor lifetime differs substantially between different technology concepts.  To ensure superior lifetime of the urea reactor in both Stamicarbon and non-Stamicarbon plants, we design urea reactors with standard 5mm Safurex ® stainless steel lining and Safurex ®  stainless steel internals. A thinner Safurex ® liner provides a significantly longer expected lifetime of the urea reactor compared to thicker austenitic …

Stamicarbon delivered the first kettle-type high-pressure (HP) carbamate condenser from Safurex ® for ammonia stripping urea plant in North America. The client can expect a longer vessel lifetime due to the Safurex ® material, which is resistant to the most common types of corrosion in HP equipment.  Stamicarbon delivered the first kettle-type high-pressure (HP) carbamate condenser from Safurex ® for ammonia stripping urea plant in North America. “We are excited to see that our cooperation with the client …

1652706000 - 1652972400 On location 50 Veemarktplein 3521 AG Utrecht Netherlands Stamicarbon Symposium 2022: Reconnect presents a valuable opportunity for us to share the latest technology insights and discuss the role the fertilizer industry can play in solving global challenges. During this three-day event, you will learn about the latest market developments, digitalization, and technologies for sustainable fertilizer production. Furthermore, the symposium provides the opportunity to catch up and network …

Carbamate Condenser New design for improved heat transfer and steam generation The Challenge  High-pressure (HP) carbamate condensers are vulnerable to chloride stress corrosion, which typically takes place in the tubes in the top tube sheet of the heat exchanger. Traces of chlorides contained in the steam condensate are deposited typically in the capillary gaps between the tube and tube sheet. These chloride stress corrosion cracks can lead to leakages, which will affect the structural integrity of the HP …

High-pressure Scrubber Improved design for increased safety and higher efficiency  The Challenge  In a high-pressure (HP) scrubber, the vapors released from the synthesis are scrubbed before being sent to the atmosphere. These vapors contain small amounts of feedstock, ammonia, as well as passivation air in combination with inerts such as hydrogen which enters the plant as contamination in carbon dioxide and other flammables. These vapors can form a gas mixture that may lead to an explosion.  Older urea …
