1. Plant Operations and Materials of Construction

Case Study- Process Gas Cooler Failure Analysis in Ammonia Plants

Abu Qir Fertilizers & Chemical Industries

Abu Qir Fertilizer Co. (AFC) owns and operates three ammonia plants. A waste heat recovery boiler “Process Gas Cooler (PGC)” is installed downstream the secondary reformer in each plant. A repeated tube failure and tube-sheet propagation of some cracks were occurred in PGC of AFC II (Stiffed type). The diagnosis revealed that the failure is mainly related to the thermal cycle over 30 years from thermal shocks during startups and shutdowns, as well as the restriction of water circulation at the back of the tube sheet (steam blanketing) which led to Dry – Wet conditions. The paper presents the actual operating problems experienced in process gas cooler in two ammonia plant in Abu Qir and the root cause analysis of their failure. it also highlights on the main critical issues have to be considered and carefully reviewed in process gas cooler designs.

Lessons Learned during root cause analysis to fix Operational Challenges of two Ammonia Plants in Nigeria

Indorama Eleme Fertilizers Limited

Indorama Eleme Fertilizer and Chemicals Limited (IEFCL) operates state-of the art Fertilizer complex in Port Harcourt, Nigeria.

The paper will discuss challenges and solutions connected with:

  • Foaming Problem in CO2 removal Section
  • Frequent variation in Primary Reformer draft
  • Conductivity variation in Package Boiler steam
  • Tube leakage in Syn loop steam generator (A-123-C1)

Shifting CO2 Injection Point from Synthesis Loop to Steam Methane Reformer Inlet in a Methanol Process


The presentation will focus on a Steam-Methane-Reformer (SMR) based methanol plant, where the stoichiometric number (defined as SN=H2-CO2/CO+CO2) is higher than optimum value for methanol synthesis application due to the reforming chemistry. The excess H2 in methanol synthesis loop ends up as unconverted gases and has to be purged out and used as fuel in reformer. Injecting CO2 in a methanol process is an effective and proven way to reduce the stoichiometric number and effectively convert waste CO2 into a value-added chemical (methanol). As a result of such practice, overall energy utilization in the plant can be optimized by either maintaining same production level with less energy consumption or increasing methanol production capacity. 

Maximizing the storage of liquid ammonia in large-scale flat-bottom tanks

Unexpected Cooling Water Ingress to Ammonia Converter Catalysts: Successful Recovery and System Improvement

PT Petrokimia Gresik

PT Petrokimia Gresik is a fertilizer company in Indonesia that recently established a new ammonia plant with a 2000 MTPD nameplate capacity commissioned in 2018. In 2020, the ammonia plant encountered an unscheduled shutdown due to an external power failure that led to the syngas compressor turbine 103-JT overhaul. After plant re-startup, it was found that the ammonia converter had been oxidated. It was later discovered that this was caused by cooling water ingress during the overhaul activities. This paper will explain how cooling water ingress happened in 2020 and how we overcame this issue to continue the plant operation at maximum load. The subject ammonia converter is horizontal type with 3 main beds.

Reliability of reformer outlet systems

Quest Integrity NZL Ltd.

The presentation covers how various components of the hot outlet collection system change and/or accumulate damage, particularly metallurgical changes that occur due to operation at elevated temperatures and the effects of in-service loading. It is important for operators to be aware of the metallurgical changes and damage that can occur for the hot outlet collection system during operation as these may not have been accounted for in the design. There is a need to understand the useful remaining life of these components to ensure continued safe operation and reliability, especially for aging plants. One aspect that the abstract highlights is around the difficulties operators face when determining the fitness for service of manifolds due to limitations in available/published materials data. Improvements that may be implemented to ensure continued safe operation and reliability is generally mentioned in the abstract.

2. Digitalisation: Digital Tools for Process Design, Production, Plant Monitoring and Operator Training. Climate and Circularity Objectives

Remote Condition Monitoring of Ammonia Plants

thyssenkrupp Industrial Solutions AG

Opportunities and limitations of applying AI machine learning for optimization of syngas plants

Navigance GmbH

The paper outlines the journey of a large European fertilizer producer to enhance their daily operation routine with AI optimization tools. Starting from one cloud-based solution to monitor plant performance KPIs in real time to applying cutting-edge machine learning models that enable operators to continuously optimize the plant operation.

Digitalization is transforming the approach to daily process optimization in chemical manufacturing. While most chemical producers recognize the benefits digital technologies can bring in areas such as plant availability and process optimization, the pace of adoption is still slower than in other industries and its implementation is a journey for every plant.

 A big barrier to successful digital projects can often be finding the time or people to spare from day-to-day operations to build and deploy the right solution. Many producers lack the in-house data-science expertise to ensure both: a clear use case and the right solution put in place to realize available technology to its full potential.

Digital technologies supporting the pathway to develop green fertilizers


The European Union's ambitious decarbonization plan, geared towards accelerating the transition while ensuring supply security in Europe, can gain substantial support from recently established fertilizer facilities powered by green hydrogen derived from renewable energy and electrolyzers. These facilities have the capability to produce green ammonia, which can then be utilized to produce nitrogen-based fertilizers.

Digital process twins provide a virtual environment to test these interactions, informing better process design, integration, and tools for real-time process optimization, aligning with environmental and economic dynamics. This research showcases how digital process twins can explore integration concepts within the green fertilizer value chain.

A novel Carbon Capture approach based on Hot Potassium Carbonate for the Ammonia Industry


The CO2 Removal from syngas is an essential and critical step in the production of ammonia, hydrogen, biofuel, and SAF (Sustainable Aviation Fuel). The choice of CO2 removal technology impacts the entire production process as it affects sustainability, costs, consumption, layout, and the balance of the plant.

Furthermore, the fight against climate change requires industrial sectors to minimize their carbon footprint. In this regard, the role of carbon dioxide capture technologies becomes even more crucial: the potential of CO2 Capture amounts to 120 MTPA for Blue Ammonia, Blue Hydrogen products.

The presentation focuses on the performance of CO2 capture systems from flue gas using HPC (Hot Potassium Carbonate) solutions in terms of:

  • Environmental impact, thanks to the use of inorganic-based solutions.
  • Tailored Layouts, based on specific plant boundary conditions.
  • Possibility to extract high-temperature heat from the process

The most efficient use of green hydrogen molecules in ammonia synthesis

Johnson Matthey

The synthesis of ammonia is an energy intensive process, consuming 2% of global energy production and generating around 3% of global carbon dioxide emissions. The urgency to develop decarbonised ammonia has never been greater with the intent of improving the energy efficiency that is translated in lower operational pressure.

Johnson Matthey recognises these challenges and has developed solutions helping to achieve decarbonised (green) ammonia. Novel green ammonia synthesis processes driven exclusively by renewable energy often consider ammonia synthesis at low pressure sometimes using high activity ruthenium-based catalyst which are both sensitive and expensive. However, recent studies performed by the University of Cambridge shown that KATALCO™ 74-1 series as an iron-based catalyst with a cobalt promoter can operate in regimes that could apply in such novel green processes where pressures and temperatures may be lower than conventional processes.


Dynamic ammonia synthesis

Haldor Topsoe A/S

Fluctuating and variable renewable source of energy adds a different dimension on the availability and flexibility needs of a new grass root green ammonia plant. Due to the variability of feedstock, traditional way of designing and operating an ammonia plant will lead to a situation of unreferenced operating model with high variability which can cause mechanical stress failures.

The dynamic ammonia technology is new with a very novel flexibility and ramping rates, which are critical for the green plants and solves very real operational problems for green plants operating on fluctuating renewable power.


H2Magallanes: A Journey to a Future of Green Ammonia


Ammonia (NH3) is vital to support the world population as a means of agricultural fertilizer. Recently, NH3 has also been considered as favorable carbon-free H2 carrier. Having a high boiling point of -33°C (at atmospheric pressure), NH3 can easily be liquefied compared to natural gas (-160°C) and hydrogen (-253°C). Therefore, making liquefied NH3 less technically challenging to transport.

TEH2, a new joint-venture established between TotalEnergies (TTE) and EREN Groupe, has secured large private lands in the Magallanes region (South of Chile near the city of Punta Arenas) that benefits from very good onshore wind conditions with access to the Pacific Ocean and Atlantic Ocean. The high wind capacity factor in the area, and the possibility of generating large-scale wind power (full field ~ 9-10 GW installed capacity) offers the possibility for the production of green hydrogen.

Reactivation of Shift Conversion Catalyst which Undergoes Unprecedented Oxidation Due to Air Exposure & Water Submersion

PT Pupuk Kujang

The presentation examines ammonia plant operational issues and troubleshooting. On March 18th 2023, Ammonia Plant 1A of PT Pupuk Kujang was operated at a rate of 100% before a sudden vacuum system problem occurred and caused severe speed fluctuation in all compressors especially the Syngas Compressor (103-J) experienced surging accompanied by rapid increase of vibration.

A thorough inspection found several damages including fracture of the feed preheater coil, leak of the 103-C tube, and some of HTS & LTS catalyst was broken down into powder. These findings indicate that HTS & LTS catalyst was exposed to air and submerged in Boiler Feed Water that subsequently resulting an unprecedented overheating higher than catalyst’s sintering temperature due to oxidation. Corrective maintenance was carried out on damaged units without any replacement due to unavailability of either catalyst or spare unit of the coil. This paper will demonstrate how the feed preheat coil was repaired and how to reactivate HTS & LTS catalysts. Thereafter, Ammonia Plant 1A is able to be operated at 100% rate with CO content outlet LTS of slightly less than 0,3% and Methanator typically less than 0,25 ppm.

World Scale Ammonia Cracking

Johnson Matthey

Ammonia cracking is an endothermic reaction with characteristics similar to those of steam methane reforming (SMR). As a result, large scale ammonia crackers are likely to bear more than a passing similarity to the steam-methane reformers which are currently used to convert natural gas to hydrogen.

Ammonia is increasingly being seen as an energy carrier due to its hydrogen component. The market is looking at ways to crack ammonia to utilise the hydrogen in a number of low carbon technologies.

6. Urea and Melamine: Process, Technology, Emissions Control  and Plant Energy Efficiency

Urea Revamp Activities in Urea plants

thyssenkrupp Uhde GmbH

The increase of urea plants capacity is in the centre of the presentation. The licensors provide various basic concepts for different capacity increase ratios. Furthermore, Uhde can independently provide smaller capacity increases of up to 10% by debottlenecking.

The significant advantage of Uhde’s proprietary process using ammonia is that the CO2 is made available already at high pressure as required for the urea synthesis (e.g. 150 bar). Today, Direct Air Capture becomes available with still small capacities of CO2 to produce a green urea from green ammonia. 

Besides capacity increase, emission reduction is of interest for revamps and can help to increase the plant output as well. Acidic scrubbings with nitric acid, sulfuric acid or phosphoric acid drastically reduces ammonia emissions in synthesis and granulation as demonstrated in Uhde plants.

Novel High-Efficiency Self-stripping Urea Process

Casale SA

The Casale presentation delivers novel solutions for “ammonia-“or “self-“ stripping process which has been a valid alternative to the CO2-stripping process for the industrial synthesis of urea since its introduction in the 70’s.

Following the demand for ever more efficient urea production plants, particularly from markets characterized by high cost of utilities, Casale has developed an improved self-stripping process to further lower the demand of medium-pressure steam and cooling water. The main innovation consists in an additional carbamate decomposition step upstream the conventional Medium-Pressure section.

Enhanced control on the prilling process using vibro prilling

Kreber B.V.

In this talk the focus will be on finding solutions to narrowing the particle size distribution, which can address known operational issues in existing prilling plants. We will discuss the basics of jet breakup, how it can be influenced and paint a comparative picture between conventional prilling in industrial fertilizer production.

Vibro prilling is a concept to gain control on the jet break up mechanics, where well-controlled periodic fluctuations (hence the name vibro) are added to the liquid flow to induce jet breakup and control the resulting PSD to be narrow. This has positive effects on the product and process quality where the standard deviation of the PSD is theoretically reduced, which can lead to less satellite droplet formation which is emitted as particulate matter from the top of the tower and a theoretical increase in heat transfer efficiency. In addition larger D50 can be manufactured in the same tower.
