Area of Science:
- Chemical Engineering
- Industrial Safety
- Environmental Toxicology
Background:
- Industrial plants operating under pressure pose significant risks, especially when handling toxic gases like ammonia (NH3).
- Effective risk management strategies are crucial for protecting human health and the environment from potential gas leaks.
- Existing safety protocols require rigorous assessment of engineering controls and chemical processes.
Purpose of the Study:
- To evaluate the safety and toxicological aspects of managing under-pressure industrial plants with dangerous gases.
- To demonstrate a safe risk control method using specific engineering devices and chemical processes.
- To provide mathematical calculations for ammonia gas flow in under-pressure systems and assess technological solutions for gas containment.
Main Methods:
- Mathematical calculations were performed for ammonia gas flow dynamics in under-pressure piping and plant systems.
- The study assessed the technological solution involving safety valves set at 20 bar for ammonia release.
- An absorption process using a water bulk five times the theoretical amount for complete NH3 absorption was evaluated.
Main Results:
- The safety valve technology was verified through mathematical calculations of the operating device.
- The absorption process effectively controlled the dangerous runaway of toxic ammonia gas.
- The proposed system ensures containment and absorption of released ammonia, mitigating health and environmental risks.
Conclusions:
- Implementing specific engineering devices and chemical processes, such as controlled safety valves and adequate absorption systems, ensures safe management of under-pressure industrial plants.
- Mathematical modeling and technological assessment are vital for verifying the efficacy of safety measures against toxic gas releases.
- The study confirms the viability of the proposed system for preventing health risks associated with ammonia leaks.
