During refining, storage, and use of petrochemical products, strict limits apply to various elements. Analyzing wear metals in lubricating oils helps monitor equipment condition and prevent unplanned downtime, while additive elements directly affect cleaning, anti-wear, and foam suppression. International fuel standards and Chinese regulations restrict metals like Mn, Pb, and Fe. Additionally, Ni and V in refining accelerate catalyst deactivation, impacting efficiency. Thus, the industry needs a fast, accurate method for metal analysis in petrochemical products.
Employing single-wavelength focused excitation technology, the PeDX SW7 significantly reduces background interference and achieves ultra-low detection limits for trace metal elements in petrochemical products. Without the need for complex sample preparation, the instrument accurately detects wear metals and additive elements in lubricating oils, restricted elements such as iron, manganese, and lead in gasoline and diesel, as well as catalyst poisons like nickel and vanadium in refining processes. With high detection accuracy and fast analysis speed, the PeDX SW7 provides a portable and efficient complete solution for metal element analysis in the petrochemical industry.
By analyzing metal elements in lubricating oil, the wear condition of mechanical equipment is monitored, enabling early warning of potential failures. |
Detect the content of additive elements in lubricating oil to ensure its performance in cleaning, anti-wear, foam suppression, and other aspects. |
Detect strictly limited metal elements such as iron, manganese, and lead in gasoline and diesel products to ensure compliance with Chinese product standards and the World Wide Fuel Charter (WWFC) requirements. |
Detect metal elements such as nickel and vanadium in raw materials or during processing, which can accelerate catalyst deactivation, to ensure the efficient operation of units such as catalytic cracking and hydrotreating. |
