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 condenser and …

Achieve higher productivity and reliability with E-type material    The Challenge High-pressure (HP) piping is often overlooked during inspection or maintenance as those are more difficult to perform in a timely and structured manner. But HP piping is exposed to the same process conditions and is therefore facing the same corrosion issues as HP equipment and can lead to catastrophic incidents in the plant if neglected.  Corrosion problems in piping can occur from the process and atmospheric sides of …

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 plants often have …

A timely replacement of the right spare part   The Challenge  Active corrosion of stainless steels caused by ammonium carbamate is a major challenge urea plant operators face every day. Even a small part of the equipment, when exposed to corrosion, could disrupt the seamless operations of your plant, requiring a quick repair or replacement of the damaged item.  But what if you could eliminate or significantly reduce the risk of corrosion in the high-pressure synthesis section of the urea plant?        The …

Bring your plant’s steam consumption to an unprecedentedly low level The Challenge Environmental concerns and the limited availability of energy resources make it necessary to reduce the energy consumption of urea plants. Especially in areas with high energy prices, reducing steam consumption of the plant can bring significant advantages. Now that’s easier said than done, you may think. But Stamicarbon has a solution. The Solution The Ultra-Low Energy (ULE) Design, part of our LAUNCH MELT™ series, makes …
