Acrylonitrile Production Unit
Acrylonitrile Production Unit
The Acrylonitrile Production Unit is a key facility in modern petrochemical complexes, producing acrylonitrile as a high-value intermediate for acrylic fibers, ABS resins, nitrile rubber, and specialty chemicals.
The Acrylonitrile Production Unit is a key facility in modern petrochemical complexes, producing acrylonitrile as a high-value intermediate for acrylic fibers, ABS resins, nitrile rubber, and specialty chemicals. The primary objective of an acrylonitrile unit is to convert propylene into high-purity acrylonitrile with stable operation, high on-stream availability, and optimized production economics. Commercial acrylonitrile plants are designed for continuous operation, long campaign lengths, and strict compliance with environmental and product quality requirements. These units are typically integrated with downstream polymer and chemical production facilities and are based on proven, licensed industrial technologies.

Overview
Ammoxidation of Propylene
Acrylonitrile is produced through the catalytic ammoxidation of propylene in the presence of ammonia and air. The reaction takes place in a fluidized-bed reactor, allowing excellent heat transfer and stable catalyst performance.
Key commercial features:
This process is widely adopted due to its reliability, flexibility, and competitive operating costs.
and Process Providers
Acrylonitrile production is based on established licensed technologies supplied by globally recognized licensors.
These licensors provide complete process packages covering reactor design, catalyst systems, separation sections, and environmental control systems.
