Thread Content

Overview of the project for an annual production capacity of 3,000 tons of Prothioconazole. Common name: Prothioconazole. Molecular formula: Molecular weight: 344.27. Structural formula: It is insoluble in water; it appears as a colorless or off-white crystalline powder that is odorless and tasteless. It is slightly soluble in chloroform and ethanol, soluble in dilute acids, and readily soluble in glacial acetic acid. Uses and features: Propiconazole offers excellent safety for crops (low toxicity, low residues, high efficacy), as well as good results in preventing and treating diseases. Moreover, the yield increase is significant. It has a broader spectrum of fungicidal activity compared to triazole fungicides. It is widely used in crops such as wheat, corn, and soybeans. Registered in multiple places since 2004, and registered in the United States and Canada in 2007. Market status: Propiconazole is a new type of broad-spectrum triazole fungicide developed by Bayer, which provides excellent control against almost all diseases affecting crops. It is a product that has been highly successful in terms of commercial development, and it is a leading fungicide worldwide. Launched in 2004, Bayer developed a series of mixed formulations based on propiconazole for use as fungicides on crops such as wheat, corn, and soybeans. The compound annual growth rate of sales over the past 10 years has been 21.6%. Currently, the global annual consumption is around 10,000–20,000 tons. Among domestic producers, Shandong Hailier has the largest capacity at 1,000 tons per year, while other factories have capacities of around 200–500 tons. These factories are small in scale and have limited technical capabilities. Given the very fast growth rate of the domestic market during its development phase, there is great potential, but current production capacities are not sufficient to meet market demand. The process is described by Equation 2; it starts with 1-acetyl-1-chlorocyclopropane as the starting material, and the target compound propiconazole is synthesized through a formylation reaction, a condensation reaction, and an electrophilic addition reaction of sulfur. This process features high conversion rate and selectivity, easy product purification, minimal generation of waste, inexpensive and readily available raw materials, mild process conditions, simple operation, and low costs. As a result, the overall product recovery rate is significantly improved to 85.9%, and the product quality reaches international advanced levels. Water is used as the solvent in the condensation reaction, which saves costs, results in less wastewater, makes treatment easier, and reduces environmental pollution. V. Raw material consumption and costs
Raw material name, Purity, Consumption per unit, Unit price, Cost
Chlorocyclopropane 99%, 1.5, 170,000 yuan, 255,000 yuan
Chlorine 99%, 4, 0.1, 0.4 yuan
o-Chlorobenzyl chloride 98%, 1, 3, 3 yuan
Hydrazine hydrate 95%, 1.5, 1, 1.5 yuan
Others: 3
Utilities, labor: 4
Total: 382,500 yuan per ton

VI. Investment requirements
To produce 3,000 tons per year, approximately 30 pieces of equipment are needed. These include enamel-lined reaction vessels, which are standard and easy to obtain. There are 15 centrifuges with a diameter of 1,000, 10 centrifuges with a diameter of 800, 3 plate and frame filter presses with a capacity of 100 square meters each. For drying purposes, 2 boiling dryers are required, along with 5 solvent recovery units. Additionally, electrical equipment and instruments are needed. Total: 60 million. The area required for utility and environmental protection facilities is 80–100 mu, with 3-story workshops ranging in size from 1,000 to 1,500 square meters; there is one workshop building and one separate building for water, electricity, and heating services. Use the open space here. One 800KW transformer is used; the remaining capacity of the factory’s transformers is utilized for cooling purposes. An additional 8–10 tons of low-pressure steam are generated for centralized supply throughout the facility. In total, this amounts to around 2–3 million units of waste generated. For wastewater treatment, 2 tons of saline wastewater are produced per ton of product, resulting in 6,000 tons of wastewater per year. The main component of this wastewater is 5% sodium chloride solution. Through triple-effect evaporation, the distilled water can be reused, allowing 300 tons of salt to be produced each year for sale. Waste gas: no waste residue. No need for a labor organization or staff; normal operation for 300 days per year, with 60 days allocated for maintenance. Four shifts per day, three shifts each; 60 employees are required. VIII. Economic analysis: At the current market price of 500,000 yuan per ton, the annual output value is 1.5 billion yuan. The annual cost is 3,000 * 38.2 = 1,146,000 million yuan; the annual gross profit is 354 million yuan, resulting in a gross profit margin of 30.89%. IX. Payback period: 60% of full capacity will be achieved in the first year, and 80% in the second year. The entire investment is recovered in one and a half years. X. Conclusion: Propiconazole boasts excellent efficacy and outstanding pest control performance; it is widely used and highly popular among users. Within just 7 years, its sales volume exceeded 1 billion dollars. In summary, the propiconazole project is a project with low risk, high returns, and substantial profits.
