H₂S in Industrial Sites

Hydrogen sulphide

Odour complaints? You must react!

Many industrial sites have the potential to release hydrogen sulphide from their production process or effluent treatment plant. This leads to complaints from neighbours around the site due to odour nuisance. In addition, the employees on the site are exposed to an insidious danger because H₂S is a toxic gas.

Fight against H₂S: Hundreds of industrial sites are already using YaraNutriox

Yara has already helped many industrial sites in Europe, and around the world in their fight against H₂S. Yara has developed a preventive solution, YaraNutriox, containing nitrates that have a preventive and durable action.

YaraNutriox: Full service, proven results, optimised costs in the fight against H₂S

  • Be in charge of your YaraNutriox consumption, while preventing any release of H₂S: we can implement the tools on your site that will give you control of your consumption of products to prevent H₂S
  • You have all the elements at hand to control the injection of the product and verify in real time the effectiveness of treatment against hydrogen sulphide.
  • You can remotely change the dosage and consume only what you really need.
Pulp / Paper mills Food / Drink Sector Refineries

Pulp / Paper mills

Paper mills sometimes produce foul odours that directly impact on the surrounding community. This odour nuisance is often linked to the release of H₂S from the internal effluent systems of the mill. It also comes from odours emitted by bacteria growing in the recirculating water.

Indeed, kraft pulp production requires the treatment of sludges and effluents before they can be discharged from the mill. The pulp and paper industry produces a significant amount of warm, effluent, with high organic matter, which creates an ideal environment for bacterial growth. These sludges and effluents in a pulp and paper mill can release H₂S, which are sources of odour complaints from the community living around the pulp and paper mills.

Many paper mills treat their H₂S with YaraNutriox

Since 1991, Yara, with YaraNutriox, its preventive process against H₂S, has helped many pulp and paper plants across Europe and the globe in their fight against the release of hydrogen sulphide and mercaptans. Biological treatment with YaraNutriox fights against H₂S to prevent the release of this odorous gas.

Mercaptans: a fast and safe solution

To avoid malodorous gases in wastewater treatment plants and sludge dewatering, Yara offers WWTP and industrial installations, EcoNOx®, a fast and efficient curative solution against H₂S and mercaptans. EcoNOx is a powerful oxidising agent. Its active ingredients are already successfully used in environmental applications, for drinking water, surface water and soil treatment. EcoNOx improves the effectiveness of flocculants for sludge dewatering. It can also precipitate heavy metals and neutralise other substances, such as phenols.

How EcoNOx acts against mercaptans?

This treatment against H₂S and odours in pulp and paper mills covers:

  • The plant’s network of sludge pipes
  • The flocculation tanks
  • The filter presses
  • The sludge storage tanks

H₂S is more than an odour problem

It is also a toxic gas against which we must protect the employees working in the plant. 

Optimise your consumption of products against H₂S

The cost of this solution depends on the complexity of the problem in your site. Our technicians will design solutions tailor made to your problem. These solutions include tools for controlling the injection of the product and verifying in real time the effectiveness of treatment against hydrogen sulphide and mercaptans. So you can change the dosage remotely and use only the product you really need.

Odour problems and food and drink industries: H₂S may be the cause of the bad scent

Most food industries generate wastewater with a high load of biodegradable organic matter. Odours caused by effluent are one of many current environmental issues related to the food and drinks industry. Hydrogen sulphide and mercaptans lead to odours that occur particularly on industrial plants such as:

  • Slaughterhouses
  • Food processing plants
  • Beverage plants

These odours directly impact on the community living around the plant. The odour nuisance may be related to the release of hydrogen sulphide (H₂S). For slaughterhouses and for plants that produce food in cans and ready-meals, effluents may be the reason why treatment against H₂S and odours is needed.

Many food and drinks factories treat their H₂S with YaraNutriox

Since 1991, Yara, with YaraNutriox, its preventive process against H₂S, has helped many food and drinks factories plants in Europe and across the globe in their fight against the releases of hydrogen sulphide. YaraNutriox is a biological treatment that fights against H2S to prevent the releases of this odorous gas.

H₂S and refineries

Odours in refineries

Hydrogen sulphide is a nuisance odour that you find in oil refineries especially around:

  • Tanks in terminals
  • Seawater separation area
  • Water ballast
  • Water tanks for firefighting

Treating H₂S in refineries with PetroCare

Since 1991, Yara, with its preventive process of H₂S developed specifically for petroleum activities, PetroCare, has assisted several refineries in their fight against releases of hydrogen sulphide. PetroCare’s biological treatment fights against H₂S to prevent the releases of this odorous gas. PetroCare also has an application in oil fields on and offshore.
