The ammonia decomposition and nitrogen purification device is a specialized piece of equipment designed to produce high-purity nitrogen by decomposing liquid ammonia and further purifying nitrogen. Its operating process includes two main steps: ammonia decomposition and nitrogen purification. This device is widely used in industrial fields that require high-purity nitrogen, such as heat treatment, powder metallurgy, semiconductor manufacturing, and electronic component packaging.

?Working Principle

1. Ammonia Decomposition: The device vaporizes liquid ammonia and decomposes it into a mixed gas of nitrogen and hydrogen through high-temperature catalysis, following the chemical equation: 2NH??→?3H??+ N?. This process typically occurs at temperatures above 800°C using a nickel-based catalyst to accelerate the reaction.

2. Nitrogen Purification: The resulting mixed gas then enters the nitrogen purification system, where hydrogen is further removed through molecular sieve or pressure swing adsorption (PSA) technology. This process achieves high-purity nitrogen with purity levels reaching up to 99.999%, meeting the high standards required for various industrial applications.

?Product Advantages

1. Stable Operation: The decomposition and purification processes are highly automated, ensuring simple operation and strong stability.

2. Cost-Effective: Using liquid ammonia as a raw material, it offers low production costs, ideal for companies requiring continuous gas supply.

3. Wide Applicability: Suitable for diverse production requirements across industries, especially where high-purity nitrogen is needed.

4. Eco-Friendly and Efficient: The device boasts high gas utilization efficiency, avoiding pollution associated with traditional nitrogen production methods.

?Application Fields

The ammonia decomposition and nitrogen purification device is widely used in various fields, including protective atmospheres in the metallurgical industry, semiconductor manufacturing, electronic component packaging, and food preservation packaging. In these applications, high-purity nitrogen effectively prevents oxidation, enhancing product quality and longevity. Consequently, this device holds an essential place in modern industry.
