Nanotech developed On Site manufacturing of chlorine gas with liquid pre-cursors as input chemicals, efficient, reliable and SAFE.
Chlorine gas is mass produced from established industrial processes. It’s stored in high pressure vessels ranging from typically 70 kg to 990 kg of chlorine in containers. The chlorine gas is in a liquid form inside these pressure vessels and are transported all over the continent on Hazchem delivery vehicles.
The transporting and handling of chlorine gas cylinders is inherently dangerous as these are manhandled. Therefore, Incidents are recorded continuously. Leakages of these pressure vessels can cause a significant number of deaths, and subsequently extensive and permanent harm to mankind.
Therefore, The equipment designed and used to convert the chlorine liquid to a gas phase needs to be inspected regularly and should be well maintained to prevent any spillages and leakages.
The capital costs for any chlorine gas installation are significant if all safety regulations are adhered to. For example, well-ventilated buildings, extraction fans, gas scrubber systems and good quality warning devices that shut off supply of the liquid or gas chlorine to the environment or process.
As a result, In most cases, the condition, quality and safety issues are not up to minimum safety standards due to lack of regular maintenance and lack of experienced personnel to manage these installations.
The most significant safety factor in these installations are the inventory of chlorine gas, liquid or gas on site. When something goes wrong, this inventory will escape to the environment. consequently, cause huge harm to everyone and everything in its way, subsequently KILLING all living species.
The “On Site” chlorine manufacturing idea was born to address significant risks associated with chlorine gas and the stringent legislation of SANS 10298:2009

Process description of Technology
The technology is a chemical process. Two pre-cursors are mixed in a predefined ratio and fed into a chemical reactor chamber for the reactions to take place. These two pre-cursors are Hydrochloric Acid (HCl) and Sodium Chlorate (NaClO3).
The chemical reactions are that of the oxidation and reduction of the pre-cursors. Therefore, The sodium chlorate is reduced to chlorine and the hydrochloric acid is oxidised to chlorine.
When chlorine output is required, the basic chemical formula is the following:
NaCLO3 + 6HCL = 3CL2 + NaCL + 3H20
This concentration is diluted with water to a safe level of chlorine gas dissolved in water.
When chlorine and chlorine dioxide output is required the basic chemical formula is the following:
2NaClO3 + 4HCl = 2ClO2 + Cl2 + 2NaCl +2H20
Firstly, The main advantage of this technology is the on-site manufacturing of chlorine gas dissolved in water and then used in the process for disinfection. In addition, The pre-cursors are hydrochloric acid and sodium chlorate which are injected into a chemical reactor chamber. This produces a final concentration of chlorine of 2000 to 3000 ppm in water.
Secondly, Added to this technology package, the process water pH will be controlled within a pre-determined range of typically 6.0 -7.5, to maximise the full disinfection potential of disinfectant, on-site chlorine generation.
Finally, the SLA agreement will take care of the maintenance of the system and components, delivery and stock management of pre-cursor chemicals and consistent final product delivery (chlorine) with minimum process availability of 98%.
