Hydrogen Sulfide Removal from Biogas – Know Issues Related to H2S

In biogas there is the presence of hydrogen sulfide is there. As hydrogen sulfide is poisonous, corrosive, and flammable its removal is very important otherwise it might be dangerous. H2S is the formula of this chemical component. This gas is not good for the environment and causes a lot of issues when found in the air. Moreover, it smells is very bad and is similar to a rotten egg smell. Its existence can be known by the smell itself. If you talk about its color it does not have any color. Based on numerous factors the concentration might vary.

 

Reasons for removal of hydrogen sulfide

 

There are several reasons because of which its removal from biogas is very important. It is a highly toxic gas and not good for health at all. Its smell is unbearable and it also irritates your eyes, nose, throat, and lungs and might cause severe damage to it. Sometimes it might be so dangerous that the entire breathing of the person might come to a halt if it is inhaled. Due to issues in breathing it might lead to the death of the person. However, if timely treatment in form of first aid is given on time might save the life of the person.

 

Process of removing it

 

Many techniques are adopted to remove this highly dangerous gas. When this gas is burnt it causes sulfur emissions in the air which is dangerous. It is thus very important to remove this harmful gas completely if it has to be used in combustion engines, turbines, and fuel cells. There might be a busting of types of equipment or damage might be caused to the types of equipment if it is not removed. So, for overall safety, it is a must to remove it.

 

Methods that can be used to remove it are as below:

 

  • Activated carbon
  • Water scrubbing
  • Iron sponge
  • Iron oxide pellets
  • NaOH scrubbing

 

Any of these methods can be used to effectively remove H2S from biogas. Try to compare these methods and see which one you will like to use. Keep in mind numerous factors such as adsorption capacity, labor requirements, cost of transportation of waste, vacuum required for emptying the filters.

 

Select the Right Company

 

You will come across many companies that are doing work of removing hydrogen sulfide removal from biogas. Take your time and try to look for a company that has at least five years of experience. Try to figure this on your own and select a reliable company to get this removal done systematically.

 

Worker and Employer – Responsibility

 

Proper training should be imparted to the workers and supervisors by the employee. This training needs to cover all the important things related to the fieldwork. The employer can keep another training section in case required. Moreover, it also becomes the responsibility of every worker to work keeping the guidelines and instructions in mind. Any worker, not following norms might be putting himself in danger and might risk his life. It is only after all the precautions are taken that work can be started.

Different Usage of Scavenger Chemicals

Before discussing the different usage of scavenger chemicals you must know what these chemicals are.

Introduction with scavenger chemicals

The chemical which can be mixed to a combination to deactivate or remove unwanted and impure reacting products like oxygen etc. to ensure the absence of unfavorable reactions are known as scavenger chemicals.

Usage of scavenger chemicals

Scavenger chemicals can be used in a wide range of applications like:

  • Hydroxyl radical is the most commonly used and short-lived scavenger chemical in atmospheric chemistry. In the environment, it is produced through a photolytic process. This oxidant is most important for removing methane, carbon monoxide, and hydrocarbons like hydrogen sulfide, sulfur dioxide, and other impurities from the environment.
  • Methane gas can be used as a gas that acts as a scavenger for separating fluorine atoms from a molecular laser isotope
  • Ascorbic acid and Hydrazine can be used as an oxygen scavenger to slow down corrosion.
  • Naringenin and Tocopherol are scavenger free radicals of bioactive nature that work as antioxidants. The synthetic counterparts of these scavengers are known as synthetic catalytic scavengers.
  • The compounds of Organotin are used as scavenger containing hydrochloric acid in manufacturing polymer.
  • Glutathione found in the body is a scavenger that oxidizes peroxides and free radicals. It also attacks dangerous exogenous toxins alkylating electrophiles, produced during the process of metabolism as a thiol nucleophile.
  • The chemicals that absorb oxygen are known as oxygen scavengers. They are placed inside the modified packs of products to improve the looks and extend the life of products packed in them as self-adhesive labels or small sachets. The iron powder packed in these labels or sachets oxidizes by absorbing the oxygen remaining in the pack if any. They also help in maintaining the safety of the product for a long time. Various types of oxygen scavengers are used these days in various types of applications.

Usage of oxygen scavengers

Oxygen scavengers are typically used in:

  • Vitamins and pharmaceuticals to prevent oxidation of vitamins like A, C, and E and extend the life of pharmaceuticals
  • The wine industry normally uses Potassium Metabisulfite not only to separate the wine from oxygen by providing a coat of gas but to scavenge oxygen also.
  • Medical devices and diagnostic kits
  • Rancidification of Foods like Snacks and nuts, Dry food with whole fat, smoked, cured, and processed meats, seasonings and spices, dairy products and cheeses, grain items and flour, etc.

Oxygen scavengers also help in:

  • Retaining the flavor of fresh-roasted nuts and coffee
  • Preventing oxidation of oleoresins present in the seasoned foods and spices
  • Slowing down the growth of mold in fizzed products from dairy and natural cheeses
  • Delaying the browning of some vegetables and fruits without any enzymatic reaction
  • Slowing down the condensation and oxidation of the red pigment of almost all types of sauces and berries
  • Providing an environment in museums free from pests by absorbing oxygen.

Thus, scavenger chemicals can be used in a wide range of applications mainly for preserving things by deoxidizing them.
