Several Safety Risks threaten Urea High Pressure Equipment like high pressures, high temperatures, various kind of corrosion phenomena, crystallization risks, large volumes and release of ammonia in case of a leak.
A significant number of serious incidents with Urea High Pressure Equipment still do occur in our industry.
And in 50% a failing leak detection system was one of the main causes.
The Risk Register for a 316L Urea Grade Reactor identifies totally 45+ safety hazards of which 75% can be prevented by operating a proper leak detection system.
Plus please do realise the typical lifetime of the 316L Urea Grade protective layer of a urea reactor is 20-30 years. While the typical lifetime of a urea plant is 40-50 years. Thus every urea reactor will finally operate close to the end of lifetime conditions of the protective layer. Meaning that at a certain moment a leak in the protective layer is nearly unavoidable.
The UreaKnowHow Leak Detection System offers the most reliable HP Equipment Leak Detection System available in the market.
With the following features:

High-pressure piping is often an area that receives almost no attention during the lifetime of a urea plant; there is no logical reason for this. Paying not enough attention or wrong inspection/repair procedures can lead to catastrophic incidents...
UreaKnowHow.com together with BHDT developed The BHDT “Zero Dead Volume“ High Pressure Sampling Valve, which makes taking samples from the High Pressure Synthesis section in a Urea Plant much more Safe, more Reliable and lot Easier. And is now available for all urea technologies. The solution will flash whereby ammonia gas releases. During sampling no gasses are allowed to escape in order to obtain a reliable and representative sample. The sample needs to be caught in a balloon in which it is dissolved in a pre-weighted amount of water. The sample flow needs to be controlled accurately in order that the sample has time to dissolve in the water and to avoid that the balloon will burst. The sampling valve and inlet line need to be pre-heated and flushed through to remove the old solution. Proper personal protection equipment is needed to avoid any risks. It is time to solve these safety hazards…
KAPP Heat Transfer Engineers, specialists in the design of heat exchangers, together with UreaKnowHow.com developed THE KAPP CO2 CHILLER, which cools the feed CO2 temperature without using cold energy sources from the existing ammonia and urea plant. This paper will describe and evaluate three options for THE KAPP CO2 CHILLER. All three options lead to extreme short pay back times as will be demonstrated in the paper.
Our services include, but not limited to:
- Technical Safety and Risk Management,
- Process Safety Documentation compliance with EU and International regulators,
- Reliability, availability and maintainability studies,
- Revamp support for Ammonia and Urea technologies,
The OFF-SPEC UREA PRODUCT UPGRADER converts off-spec urea product (lumps, fines and dust) into a premium quality urea product, namely Urea Super Granules. Urea Super Granules are part of the Urea Deep Placement technology developed by the International Fertilizer Development Company (www.ifdc.org) in the US with the target to increase rice yields with reduced nitrogen-fertilizer application and reduced nitrogen losses.
How to keep your urea plant in optimum shape ?
- And how to realize a maximize reliability and on stream figures minimizing unplanned shut downs and keep safety standards up to date?
- And what about future debottlenecking possibilities ?
UreaKnowHow.com offers now Health Check services covering all these aspects !
Statistical Process Control is a good way to check, but more-over control your product quality, and reduce the amount of complaints and overdosing of formaldehyde, and avoid caking and dust in the warehouse. Typically one wants to do quality control on the Size Guide Number (SGN) and Uniformity Index (UI), because these parameters determine how ones fluid bed granulation or prilling plant is running. One can also opt to apply Statistical Process Control on the load-out product, to enable a product certification and happy customers...More information
Baffle hammering is a widely occurring failure mechanism in heat exchangers. In urea plants baffle hammering has been experienced in various heat exchangers such as HP scrubbers, Low Pressure Carbamate Condensers and Kettle type carbamate condensers. By means of HTRI a specific vibration study can be performed to prove that indeed critical vibration do occur under the current conditions and which measures are necessary to realize a vibration free design. UreaKnowHow.com has experience to perform these HTRI studies in co-operation with HTRI specialists. For more information, Download the PDF
SKW Pieteritz in Germany has successfully developed a reliable pressure transmitter for the high pressure synthesis section in any urea plant. This pressure transmitter is part of the Innovative Overpressure Protection System for high pressure urea synthesis sections, which was presented during the AICHE Ammonia Safety Conference 2012 and is offered by the Safety Valve producer LESER in Germany (www.leser.com). It has been agreed between the parties involved that UreaKnowHow.com will offer the pressure transmitter itself to urea producers. To measure the pressure in a high pressure gaseous or liquid carbamate lines, several challenges are to be encountered: crystallization, erosion and corrosion risks. Solutions have been found to avoid these risks and these pressure transmitters are successfully in operation since September 2011. For more information, download the PDF
UreaKnowHow.com has the know how and experience to support you with your new Grass Root Urea Plant or Urea Revamp Project. UreaKnowHow.com can support you in a wide range of services and activities during the complete project lifetime.
Vertical One Pass (VOP) heat exchangers are many times applied in urea plants. As the residence time in these heat exchangers is small, unwanted side reactions like biuret formation and hydrolysis of urea are limited. Some phenomena however limit or reduce the performance of these heat exchangers: Bad distribution of gas and liquid at the inlet and consequent fouling of the tubes. UreaKnowHow.com offers a very reliable and maintenance friendly solution to improve the performance of VOP Heat Exchangers. This solution have been proven since 2011 and increases the performance and reduces the fouling tendency in a medium and low pressure recirculation heater. The restriction orifices are very easy and quick to install and remove during a shut down. For more information, download the PDF
Energy costs have a significant impact on the production costs of the urea product. Older urea plants have to compete with large scale new plants however suffer typically from higher energy costs due to the applied older technologies and due to lower efficiencies of older machines. UreaKnowHow.com co-operates with a group of energy management specialists with totally more than 40 years experience in energy management and revamp projects to improve the energy performance figures of your urea plant and reduce the variable urea production costs. Step 1 of such a typical Energy Reduction Revamp project is a Quick Scan of the actual energy situation in your urea plant.
Dusty urea product leads to many problems with clients, employees, transporters and farmers. Dusty urea product is typically caused by operation parameters of the evaporation section in the urea melt plant, operation parameters of the granulation or prilling section, storage conditions and logistic procedures. In most of these cases an end-of pipe solution is the most efficient and cost-effective solution to improve the product quality and produce premium-grade urea. The “Van Bommel Dedusting Technology” (VBDT) offers such a solution. For more information, download the PDF
