Sul-free H2S Scavenger & Acid Gas Eliminator

Sul-free™ products are a new group of organo-imino compounds that offer significant advantages for treatment of Hydrogen Sulfide. Its chemistry specifically targets Hydrogen Sulfide, organo-sulfur compounds, and mercaptans. This unique new chemistry is synergistic with wastewater systems, bacteria, and enzymes. In field wastewater applications Sul-free™ WS 1500 quickly and specifically binds up sulfur. This includes stripping sulfur from the poisoned aerobic bacteria and enzymes that are beneficial and have been deactivated by the sulfur bond. This reaction has shown the benefit of a natural increase of O2 that in turn optimizes the bio-chemical balance of the system. Sul-free™ does its job and frees the bacteria to do theirs. Its pleasant, safe aroma eliminates foul odors while it reacts with the Hydrogen Sulfide and mercaptans. They are removed indefinitely from the solution.

Sul-free™ has no negative impact on downstream operations. The chemistry biodegrades completely in normal wastewater treatment processes without loading solids into the system. Sul-free™ is a breakthrough in economic treatment of wastewater. Low chemical addition rates and catalytic regeneration of the Sul-free™ molecules mean that it can be the lowest costing Sulfide scavenger; cheaper than any treatment on the market. There is no need for special pumps, tanks, or chemical resistant piping. Sul-free™ is the lowest costing treatment on the market, however efficiency is its greatest asset. Sul-free™ demonstrates low toxicity. It is not corrosive to concrete, steel or plastic, and requires no scrubbers. Sul-free™ can be diluted to fogging levels (between 1 and 3000 ppm), safely removing poisonous and corrosion-causing Hydrogen Sulfide, mercaptans, and foul from various locations. It can be fogged above tanks, settling ponds, sludge dewatering areas, lift stations, air gaps, manholes, and culverts.

Sul-free™ OS products are the oil soluble scavengers for the petroleum, refining, and natural gas industries. These scavengers are application driven to remove sulfur odors from sour fuels and lubricating fluids and to reduce corrosion in transmission lines. High solubility along with high Sulfide bonding capacity per molecule allow effective removal of Hydrogen Sulfide and mercaptans without introducing water into an oil based system. Oil and fuel solubility prevents off gassing of sulfur odors, while the ashless molecule burns like diesel fuel. Sul-free™ is truly a step forward in Hydrogen Sulfide scavenging technology. It is a product that is reaction specific and without toxic consequences. Truly a product that is useful to many industries, including wastewater treatment and petrochemical refining, Sul-free™ removes foul smelling sulfurous chemicals from systems and from the atmosphere.

Until today, Hydrogen Sulfide treatments generated many disadvantages…

-Special scrubbers needed for Chlorine- required by OSHA
-Creation of Sludge
-Creation of Scale
-Generation of Acid in process
-Generation of Nitrates
-Special handling procedures and training required
-Short lifespan of chemical interaction
-Inability to deal with spikes due to temperature or loading factors
-Loss of chemical effectiveness before reaction with sulfides
-Corrosive, oxidizing, and poisonous chemical hazards
-Chemical additives require special equipment (tanks, pumps, and specialized piping)
-Chlorine, Hydrogen Peroxide and Nitrates as oxidizers are bio-interrupters, inhibiting and killing beneficial bacteria, and interrupting the system function
-Chlorine has a short lifetime in wastewater, consumed by everything in the wastewater

Advantages of using Sul-free™...
+Requires low additional chemical+Degrades in anaerobic conditions to Methane, CO2, and H2O
+Does not require special handling
+Does not have a short lifespan+Does not generate sludge (not a precipitator)
+Does not cloud water+Does not generate scale
+Decreases corrosion+No negative downstream effects
+No specialized scrubbers, tanks, pumps or mixing stations
+Not an acid+Not an oxidizer
+Not quickly consumed by wastewater+Not volatile, so it stays in aerobic solutions
+Not a gas+Not regulated+Lower Cost
