How Fuel Additives Can Improve Fuel Quality and Refining Productivity and Profitability with Case Studies

Proper application of the biocides resulted in effective kill and control of MB in distillate storage tanks. Monitoring and testing was included in the application. SpecAid 8Q700 series products are effective biocides for MB, including the more resistant strains and SRB. Typical kill time is less than 24 hours for most applications. Read More ›

Chemical treatment strategies for processing heavy crude oil

Desalting, solids and metals removal, and preheat fouling control are just some of the challenges currently facing the heavy processing industry. Crude compatibility studies for heavy oil blending can prevent the precipitation of asphaltenes and, with the use of desalting aids, additives and preheat antifoulants, a 75% reduction in fouling can be achieved.
