Sulfiding Services

In 2012, Reactor Resources (RxR) established the “standard in sulfiding” with the introduction of our patented SmartSkid™ DMDS Injection System. The SmartSkid is the first and only patented system designed specifically for catalyst sulfiding. the technology in these custom built skids allows our technicians to provide the safest and most accurate injection of sulfiding spiking agents. In addition, RxR supplies sulfur spiking agents including dimethyl disulfide (DMDS) and polysulfides such as TBPS 454 and/or Sulfrzol® 54. Precise and controlled injection ensures that your hydrotreating and hydrocracking catalysts will reach their maximum activity level and/or highest yield.   Learn More About Our SmartSkid Injection System and Gas Analyzers »

MDEA Injection

Reactor Resources has extensive experience injecting methyldiethanolamine (MDEA), ammonia, and other chemicals used for in-situ catalyst treatments. In the past, refiners used ammonia to passivate hydrocracking catalysts with nitrogen in order to reduce the risk of temperature excursions caused by hyper-active catalysts. Other chemicals, such as tributylamine (TBA), have also been  used as an alternative to ammonia. These compounds decompose to form ammonia at typical sulfiding conditions.

In order to improve the safety and reliability of nitrogen passivation, RxR pioneered the use of MDEA as a passivating agent. Based on its Health Hazard Classification of 1 (the safest class), MDEA is much safer to handle than both TBA and ammonia, while still providing the nitrogen needed for passivation. MDEA has a low cost, a high nitrogen density, and is readily available across North America. In fact, most refiners are already using this chemical in their sulfur plant to treat sour gas.

To eliminate issues caused by non-decomposed mercaptans, Reactor Resources created a customized approach to sulfiding called EnviroSulf™.  Working closely with your team and the catalyst vendor, RxR will design a sulfiding procedure and select a mix of sulfiding chemicals that is guaranteed to eliminate any non-decomposed mercaptans. And by utilizing our Dual Total Sulfur/H2S Analyzer, we can ensure that there are no mercaptans remaining in you recycle stream.
