Riel Chemical Co., Ltd.

Against the backdrop of the global chemical industry moving towards green and high-end development, Riel Chemical has officially reached a strategic cooperation with SABIC, a leading diversified chemical enterprise in the world. This collaboration will integrate SABIC's innovative material technology with our industrial advantages in chemical raw materials to jointly promote the application of high-performance materials and the realization of sustainable development goals.

SABIC is a leading global chemical giant with business covering polymers, chemicals, agricultural nutrients and metals, among other fields. With over 40 years of R&D experience, our patented technologies cover cutting-edge fields such as lightweight materials and renewable energy solutions.

SABIC provides high-performance materials (such as engineering plastics and specialty chemicals), and we supply oxalic acid.

Develop eco-friendly packaging materials based on SABIC's TRUCIRCLE™ recycled polymer to reduce carbon footprint.

Our oxalic acid is just right, improving energy efficiency and material utilization rate.

Our cooperation with SABIC is not only a win-win business situation, but also an embodiment of the concept of "responsible care". Through the sharing of resources and technologies, both sides will provide customers with lower-carbon and higher-performance solutions

In the future, both sides will continue to explore in-depth cooperation in fields such as new energy vehicles, electronic appliances, and medical materials, and promote the transformation of the chemical industry towards a circular economy.

Riel Chemical Co., Ltd. uses advanced production processes, such as the following example to manufacture high quality sodium tripolyphosphate (STPP). The process mainly includes phosphoric acid neutralization, drying, polycondensation and finished product packaging, the specific process is as follows

1. Preparation and neutralization of raw materials
The main raw materials for producing sodium tripolyphosphate are phosphoric acid and soda ash. Depending on customer requirements, we can use the hot phosphoric acid process or the wet process

Thermal phosphoric acid process: phosphoric acid

Phosphoric acid and soda ash are neutralized under controlled conditions to form sodium orthophosphate solution. The pH value and raw material ratio during the neutralization process are strictly controlled to ensure the stability of the subsequent polymerization stage.

2. Spray dry
The neutralized orthophosphate solution was dried in a spray drying tower to form an anhydrous sodium phosphate powder. The heat source temperature of the drying tower is controlled at 600-700℃, and most of the dried powder is collected from the bottom of the tower, and a small part of the powder is recovered through the cyclone separator to ensure the material

3. Calcination and condensation
The dried sodium phosphate powder is burned in a high temperature rotary furnace at a temperature of 350-450 ° C and a proper residence time is maintained. In this process, sodium phosphate is demineralized and polycondensed to form sodium tripolyphosphate. In order to control the crystal form and quality of the product, a small amount of catalyst such as ammonium nitrate (NH₄NO₃) can be added during the sulfuric acid sintering process to accelerate the reaction and obtain a more stable STPP-Ⅱ crystal form.

4. Quality control
At every stage of production, we carry out rigorous quality control tests to ensure that sodium tripolyphosphate products meet high standards of purity, solubility and chemical stability. The products are fully tested before leaving the factory to meet the application needs of various fields such as food, industrial and water customer handling.

Riel Chemical Co., Ltd. is committed to providing customers with high quality chemical products that meet international standards. We adopt a strict quality control process to ensure that each batch of products from raw material procurement to finished products are strictly tested and monitored to meet the high standards of customers. 

1. Inspection of raw materials
When purchasing raw materials, the quality inspection department will strictly screen suppliers and select raw material suppliers that meet international standards. After each batch of raw materials arrives at the factory, it will undergo strict physical and chemical properties testing to ensure that its purity, composition and quality meet the production requirements.

2. Production process monitoring
In the production process, we use advanced automation equipment and precision control systems to ensure that every step is operated within standard parameters. Technicians monitor key parameters such as temperature, pressure and time during the production process in real time to ensure that products meet established quality standards.

3. Random inspection of intermediate products
Intermediate products are sampled at different stages of production, including purity, composition and physical properties. The intermediate test results will be used to adjust the production parameters to ensure stable quality of the final product.

4. Finished product inspection
After production is completed, each batch of finished products is thoroughly tested, including purity, composition, pH, solubility and many other indicators. We work with third-party testing organizations to independently test our products to ensure they meet customer specifications and international standards.

5. Package and label check
After the finished product passes the inspection, it enters the packaging process. The packaging department ensures that the packaging of the products is complete, well sealed, and accompanied by accurate labeling information, including product name, specifications, lot number, etc., so that customers can trace the source and quality information of the products in subsequent use.

6. Quality review before delivery
Before shipment, the quality inspection team conducts a final review of each batch of products to confirm that all quality documents and inspection reports are complete. Qualified products can be shipped from the factory to ensure that every product delivered to customers meets the highest quality standards.

7. Customer feedback and improvement
We attach importance to customer experience and feedback, and regularly visit customers to understand the performance of products in the use process and collect suggestions for improvement. Customer feedback will be used to improve quality management processes and production processes to continuously improve product quality.
