Khorasan Petrochemical Company (KHPC) has recognized a growing demand for a specialized fertilizer known as Sulfur Coated Urea (SCU). SCU fertilizer is known for its ability to control the release of nutrients, especially in comparison to other forms of urea fertilizer, and is particularly preferred for use in paddy fields.
The plant is designed to produce 90,000 metric tons per annum (MTPA) of SCU fertilizer, which is packaged in bags. The raw materials required for production include Urea (in both prill and granular forms), Sulfur (in powder form), and Wax (in solid form).
The SCU Plant consists of the following civil units:
• SCU Unit
• Sulfur Unloading, Storage & Melting System
• Wax Unloading, Storage & Melting System
• Urea Handling System (including Transfer Tower and Screening Building)
• Product Bag Filling & Storage System
• MCC & Control Room
