Stamicarbon - Nitric Acid
Nitric acid is an important chemical compound, with about 80% of total production dedicated for application in the fertilizer industry. Now, the challenge is: how to design a nitric acid plant with maximum energy recovery and lowest investment costs, which meets even the most stringent environmental standards?
The solution: Stamicarbon Mono- and Dual-Pressure Nitric Acid Designs
Stamicarbon offers mono- and dual-pressure nitric acid production processes for a wide range of plant capacities up to 600 MTPD (mono-pressure) or 2000 MTPD and above (dual-pressure). Both processes are characterized by high tail gas temperature and designed for maximum energy recovery, reliable operation and minimal greenhouse gas emissions.
Mono-Pressure Design
- Ideal for lower plant capacities (
- Lower capital investment (CAPEX)
- Possible integration with small-scale Stami Green Ammonia technology
Dual-Pressure Design
- Ideal for higher plant capacities (>600 MTPD (100% HNO3) with single equipment)
- Lower energy consumption (OPEX)
Stamicarbon`s design reduces the total cost of ownership significantly by maximizing the energy recovery of your plant and extending the equipment`s lifetime.
When choosing Stami Nitric Acid, you receive the following advantages:
- Reliable process
- Highest energy efficiency
- Ease and safety of operation
- Low emissions
- Corrosion prevention design
- Full lifecycle support
The main feature of the Stamicarbon nitric acid process is the position of its third tail gas heater. Its location in the ammonia burner vessel allows tail gas temperatures of 480 °C, which has several advantages:
- Nitrous oxide decomposition without the addition of an external agent like natural gas
- Higher power generation in the expansion turbine
- Extra heat recovery step before releasing the tail gas into the atmosphere
- Lower steam consumption of the compressor train and thus higher steam export
Safety is the number one priority for Stamicarbon when designing a nitric acid plant – just as it is for all our technologies. During plant start-up, ammonia slippage can increase the risk of forming explosive ammonium nitrate and ammonium nitrite in the low-pressure cooler condenser and the first compartments of the oxidation/absorption column. Stamicarbon`s latest design is characterized by accurate control of the process to minimize ammonia slippage and additional safety measures to prevent unsafe situations during the start-up.
