In the petrochemical industry, the purity of feedstocks is directly linked to the quality of final products and the efficiency of production processes. Naphtha, a key feedstock derived from crude oil, often contains chloride impurities that must be addressed to prevent significant operational issues. Specialized dechlorination agents, such as advanced catalysts, are indispensable for this task. NINGBO INNO PHARMCHEM CO.,LTD. provides high-performance solutions for effective feedstock purification.

Chloride compounds in naphtha can cause a cascade of problems within a refinery. These can range from corrosion of metallic components in processing units to the deactivation of valuable downstream catalysts. The presence of even small amounts of chloride can lead to the formation of acidic byproducts or corrosive salts, which can significantly shorten the lifespan of equipment and increase maintenance expenses. Therefore, rigorous naphtha chloride removal is a standard practice in modern refining operations.

High-temperature chloride removal catalysts are particularly effective in treating naphtha. Their ability to operate efficiently at elevated temperatures, common in refinery processes, makes them suitable for direct integration into the naphtha treatment stream. These catalysts are designed to capture or react with both inorganic chlorides (like HCl) and organic chlorides (RCl) that may be present in the naphtha. By doing so, they ensure that the feedstock entering the catalytic reforming units or other downstream processes is free from detrimental contaminants.

The effectiveness of these agents is measured by their capacity to significantly reduce chlorine levels. Leading products can bring down initial chlorine concentrations of up to 1000-2000 ppm to less than 0.1 ppm. This high purification degree is crucial for protecting sensitive catalysts, such as those used in catalytic reforming, which are vital for producing high-octane gasoline components and aromatic chemicals. Without effective dechlorination, these catalysts would quickly lose their activity and require premature replacement.

Beyond just naphtha, these potent dechlorination agents are also valuable for purifying other industrial gas streams, including synthesis gas and coke-oven gas. In the production of synthesis gas, which is a building block for many chemicals and fuels, maintaining absolute purity is critical for the efficiency of synthesis reactions. Similarly, coke-oven gas, a byproduct of coal carbonization, requires purification before it can be used as fuel or a chemical feedstock. The high temperature chloride removal catalyst ensures that these streams meet the stringent purity standards required by the industry.

The operational advantages of using these advanced catalysts are substantial. They offer sufficient mechanical strength to withstand process conditions, along with excellent stability and selectivity, meaning they target chlorides effectively without interfering with other desired reactions. This reliability translates into smoother operations, reduced downtime, and improved overall profitability for petrochemical facilities. NINGBO INNO PHARMCHEM CO.,LTD. is committed to advancing these critical technologies for the benefit of the global petrochemical industry.
