CarbonSeal and Hydrogen Sulfide Removal

CarbonSeal has been used successfully to remove hydrogen sulfide from water, air, oil wells, factory stacks, ground water, waste water, garbage and medical waste. It typically removes 92% to 99.3% of hydrogen sulfide.

Hydrogen sulfide (or hydrogen sulphide) is the chemical compound with the formula H2S. This colorless, toxic and flammable gas is responsible for the foul odour of rotten eggs.

It often results from the bacterial break down of organic matter in the absence of oxygen, such as in swamps and sewers (anaerobic digestion). It also occurs in volcanic gases, natural gas and some well waters. When released as a gas, it will change into sulfur dioxide and sulfuric acid. In some instances, it may be released as a liquid waste from an industrial facility.

When removing hydrogen sulfide, every application varies in the required amounts, concentrations and methods.

For example, in sewage treatment, a 100% concentrate is sprayed in a mist directly onto the source, at a rate of one part CS to 10,000 parts sludge to remove hydrogen sulfide, if left for between 18-24 hours; but for sewage treatment odors, a 1:50 ratio can be used in an automatic fogging system over the holding tank.

In the stagnant water, use 200 liters of CarbonSeal for each 1000 square meters.

In the oil and gas industry, hydrogen sulfide causes other problems. Because it is toxic, it poses a risk to workers. Because it is acidic, it can damage pipes. Natural gas can contain up to 90% hydrogen sulfide.

In wells, up to 99% of the hydrogen sulfide can be removed by bleeding the gas out of the well through a 3 inch pipe where CarbonsSeal is injected to react with the gas. The mixture is then bubbled through a drum containing water.

Lint filter traps kept continuously wet with a 50/50 mixture of CarbonSeal and water have also proven effective as a containment of hydrogen sulfide released through vents in factories and oil wells.

A few of the factors that can cause variations in applications include:

  • Temperature
  • Air flow
  • Iron content
  • Carbon content
  • Organic element content
  • Tank size
  • Discharge rate

Because of this, the best success can be achieved through experimentation, varying methods and concentrations.
