Anhydrous Ammonia has advantages over ammonia solution and urea when lower NOx emissions are required. With proper storage, correct handling and understanding of the product, this reagent can be safely used.
Anhydrous Ammonia is undiluted Ammonia. It can be used directly with selective non-catalytic reduction (SNCR) and selective catalytic reduction SCR systems either in the gaseous form (most common) or it can be injected in the liquid state. Anhydrous Ammonia is usually stored under pressure (5-10 bar) or it can be stored at atmospheric pressure if kept at -33°C.
For control of NOx, Yara recommends the use of Ammonia, where possible because of the advantages it has over alternative options. It:
Yara is a world leader in supply and safe transport of Ammonia in different states, producing over 7 million tons in 2016.
Most of our Ammonia is made from natural gas, the cleanest hydrocarbon source available.
Yara has been dealing with Ammonia for over a century, and we have an exemplary safety record, as safety is at the heart of all our operations. We are also happy to share our safety expertise with our customers.
Anhydrous ammonia transport methods include:
Yara delivers the reagent of your choice from our unique network of plants offering a constant back-up in sourcing. Yara can also offer Anhydrous Ammonia dilution units close to, or at, your site. This means:
Ammonia is the ultimate, cost-efficient SNCR and SCR reagent, and safe when handled correctly.
To ensure that best-practice safety is maintained from production to consumption, we train our own people and contractors extensively, If your staff need training on ammonia storage and handling, we can answer all your questions and organize training sessions.
You can get expert training or advice on a number of different safety related services, such as:
You can manage, and in some cases optimize, your SNCR and SCR reagent logistics with Yara's telemetry solution.
Your telemetry system triggers a delivery order when your predefined level is met. All telemetry orders are automatically delivered, securing your supply, direct to you where you need it. But you can still be involved in the telemetry process, if required, so that you remain in control at all times.
Get an effective supply planning tool that enables your reagent to be supplied on automatic request. This gives you an improved intervention capability via a fully transparent system, which also provides you with a complete overview of your stock levels and trends 24/7.
Benefit from tank level monitoring, to data collection and transfer, to a user friendly web-based monitoring system, which can be accessed from your process computers, office computers or smart-phones and tablets – all installed by Yara as part of our telemetry package.
If you need storage solutions for your NOx reduction reagents – Ammonia, Ammonia Solution and Urea Solution – we can help you with the design, build and upgrade of storage facilities. This can be as part of your SNCR, SCR or hybrid system installation, or as a stand-alone storage tank solution.
To ensure that your current reagent usage is as efficient and cost-effective as possible, we can make an optimization assessment of your current usage.
If your reagent situation changes, we can recommend and deliver, standardized or customized, NOx reduction reagent storage solutions and internal site distribution solutions to your NOx control installations.
