Biodegradable Non-toxic Non-hazardous Non-corrosive Spray manually Rooftop Spray Soak & wash Inject with steam Flush pumps Use at any temperature Works instantly Stable (irreversible reaction)
Hg droplets create invisible vapours
After 30 seconds Hg vapours = 0.056mg/m3
Area is sprayed with MeDeX 80
After 5 seconds Hg vapours = 0.001mg/m3
MeDeX 80 is a formulated chelating agent able to chelate ionic mercury present, forming a stable compound that is very soluble in aqueous medium, while functioning aggressively in elevated temperatures or ambient conditions.
Hg + MeDeX 80 Hg Salt + H2O
Our chemists have come up with a ground breaking innovation to decontaminate mercury from contaminated vessels, tanks, vapour spaces, spills, etc.

Hydrocarbon Decontamination (LEL/VOC) Mercury Vapour
LEL & VOC
Hg Desorption
HyDeX is a breakthrough in chemical technology which can massively reduce decontamination time
Decontamination of large systems takes an average time of 8.25 Hours!!
Chemical usage is a fraction of traditional methods
Application requires less equipment and less manpower than existing methods while being effective at any temperature
HyDeX reduces shutdown waiting period for Degassing, LEL, Hydrocarbon Free by decontaminating VOC, CO, H2S, Iron Sulphides and Pyrophoric Polymers
HyDeX EXCEEDS WORLD STANDARD TURNAROUND SAFETY CRITERIA

Desorption of Mercury (Hot Work & Disposal) Mercury Vapour
LEL & VOC
Hg Desorption
Mercury adsorbs to the surface of metals such as SS304/316 Mercury absorbs within the surface matrix of carbon steel(s) with the depth of Hg penetration varied depending on various factors
Normal Conditions 10m Pressure/Temperature 20m-150m
Extraction of Mercury
Thermally Chemically
Lixiviant Pickling Solution
Vacuum Kinetic Process Combined System
The removal of elemental and compound Mercury that has been absorbed into vessel and pipeline walls (Absorbed) is possible using a solution that entices the Mercury out through an engineered pickling-like process before stabilizing it as a Sulphur compound (Mercaptan). The ONLY chemical independently proven to do this is MerCure MerCure is water based and contains sacrificial and non-detrimental components in a synergistic and fast acting formula.

Desorption of Mercury (Hot Work & Disposal) Mercury Vapour
LEL & VOC
Hg Desorption +
The desorption of elemental and compound Mercury prior to hot work on contaminated steel is a MUST to protect personnel from (lethal) elevated Hg vapours and can be achieved quickly and effectively with MerCure
The desorption of elemental and compound Mercury prior to disposal of contaminated steel is a MUST and can be achieved quickly and effectively with MerCure to ensure safe disposal criteria is met. The decontaminated steel is pre-cut to ensure swift handling directly into steel mills without the need to cut further by 3rd party with or without the correct PPE.
MerCure is (currently) capable of:
67% reduction in 10 mins
XRF analysis of Hg-contaminated bulk head
Demolition of decond steel pipe
Hot work on Hg-contaminated steel pipe spools

The effect of a 5% addition of PARALAX on 14 API Crude Oil
Where hydrocarbon sludge has solidified or waxed up, the viscosity of the sludge can be reduced with paraffin wax returning to solution and separation phases becoming more pronounced and easier to achieve with the addition of Paralax
Solidified sludge
Addition of water shows the separation of oil from solids
Paralax can be injected online or applied manually (offline)

Heavy Metals Encapsulation
Encapsulation
Oil Recovery
Heavy Metals, including Mercury, can be encapsulated and rendered INERT with the addition of HM Fix e.g. Hg-contaminated pipe from an LNG facility was filled with the HM Fix solution in a 10:1 ratio with water. This was allowed to sit (soak) for 1 hour before being cleaned out using PIGs. Analytical wipes were taken from the surface both before and after the treatment
