No Heat Resources is a chemical inventor who specializes in H2S treatment as well as hydrocarbon and mercury decontamination. No Heat "HydraScav" is a water based chemical able to remove H2S and Mercaptans from hydrocarbons and extremely low rates. It is NOT triazine or formaldehyde based and its chemistry is totally different to the 100's of scavengers in the market. The injection rate is 3ppm of HydraScav for each 1ml/litre of H2S / Mercaptan. HydraScav is water soluble and is extremely effective in removaing H2S and all sulphides from water. The injection rate is around 3ppm of HydraScav for each 1ml/litre of sulphides. HyDeX 100 is a non ionic surfactant that is able to remove HC gases, H2S & CO2 from a vessel at ambient temperature (thus the name "No Heat"), by simply spraying! This cuts down decontamination time drastically and reduces the need for nitrogen purging. MeDeX 80 is a Mercury Decontamination Chemical that is also sprayed into the vessel to remove toxic mercury vapour. Used in conjuction with HyDeX 100 these chemical offer a complete decontamination package.
