DUST SUPPRESSION SYSTEMS

The dust suppression system allows the removal of dust in the working place quickly and effectively, ensuring the health of the worker and maintaining the efficiency in the production.

Fields of Application on Dust Suppression

COAL HANDLING SYSTEMS / COAL DUST POWDER SUPPRESSION

The Dust Suppression System is meant to suppress the coal dust generated during transferof coal at feed/discharge points of conveyors in various transfer towers.

Coal oxidation causes material loss and fuel degradation.

Coal mining presents a number of specific hazards, ranging from collapse and flooding to dangerous explosions. Dust created by mining activities presents a hazard because its pervasive nature creates a number of breathing-related issues for people, as well as maintenance issues for machinery. Dust also creates a potentially explosive environment. Every year, an unacceptable number of people are injured or killed in underground coal mining accidents or suffer long-term health issues as a consequence of exposure to coal dust.

Coal dust is a proven carcinogen and also causes pneumoconiosis (more commonly known as miners’ lung disease) so suppression of coal dust in an underground mine is critical. High levels of dust in the atmosphere when mixed with gas can also create an ignition hazard, in addition to being a source of premature wear and breakdowns on various pieces of mining equipment.

The problems arising from coal dust emissions can be severe, and the methods to control the emissions can sometimes be inadequate.

An effective system for the control of fugitive dust in Industry should meet the following objectives.

• Must be efficient to meet Health & Safety requirements.

• Be practical and simple in operation.

• Have low initial cost.

• Have low operating costs.

• No adverse effects on product quality or plant and machinery should be created.

Three types of dust control methods exist – containment, collection and suppression – all of which are widely used with varying degrees of success.

SULPHUR HANDLING SYSTEMS / SUPLHUR DUST SUPRESSION

Sulphur that is mined or recovered from oil and gas production is known as brimstone, or elemental Sulphur. Sulphur produced as a by-product of ferrous and non-ferrous metal smelting is produced in the form of Sulphuric acid. A smaller volume is produced as Sulphur dioxide, which is also emitted from petroleum products used in vehicles and at some power plants. Plants absorb Sulphur from the soil in sulphate form.

Elemental Sulphur is produced all over the world. Largest production occurs where sour (meaning Sulphur-rich) gas and oil is processed and refined.

Sulfur is corrosive, polluting and hazardous with the potential to explode and cause fires. It is especially polluting when handled with machinery such as grab cranes and bucket elevators. Sulfur operations attract increasingly strict regulation to eliminate spillage and minimize dust emissions.

Sulfur occurs in various forms in oil and gas production activities, and its management has brought a new set of challenges to the forefront of oil and gas production. Elemental sulfur deposition problems affect pipeline production operations in many oil industries across the globe, and it is extremely costly to mitigate. The heightened cost of this deposition issue can be attributed to the scant knowledge available on elemental sulfur formation in sour gas.

Production of Sulphur carried out in three basic ways:

  • Mined through the use of wells drilled to Sulphur deposits;
  • Extracted from the oil or gas stream at a processing plant;
  • Scraped from the surface of the earth or dug out of open pits.

The main uses of Sulphur

    • The main use of Sulphur is in the preparation of SO2 which is used in the manufacture of Sulphuric acid.
    • Sulphur is used in the manufacture of carbon disulphate, sodium thiosulphate, gun powder, matches and in fireworks.
    • Sulphur is used on vulcanization of rubber. Natural rubber is soft and sticky. Heating it with Sulphur makes it hard non-sticky and more elastic. This process of heating of natural rubber with Sulphur is known as vulcanization.
    • Sulphur is used as fungicide and insecticide in agriculture and as a disinfectant in medicines.
    • Sulphur is used in ointments for curing skin diseases.

Sulphur is used in beauty parlors to give specific shapes to the hair.

Handling Sulphur can be a dangerous task. Fine Sulphur particles are flammable, and improper handling can lead to major safety and environmental concerns. It is critical to implement the proper equipment to ensure the safety and security of every forming facility.

A combination of factors has resulted in Sulphur being extracted from crude oil and gas in greater volumes than ever before:  a growing world population means increased demand for energy;

The world’s remaining hydrocarbon reserves contain higher levels of Sulphur than previous fields;

Changes in environmental legislation have led to a continuing reduction in the amount of Sulphur permissible in fuel, resulting in Sulphur recovery efficiency levels as high as 99.9%.  Global output is now in the region of 60 million tons p.a. (of which approx. 95% is recovered from oil and gas sources). By definition recovered Sulphur is produced in the greatest quantities in those areas where oil and gas is refined: North America, Russia, China and the Middle East.

In terms of demand, huge amounts of Sulphur are now required for the production of agricultural chemicals and fertilizers; this is due to a combination of ever more intensive farming methods and the removal of Sulphur from fossil fuels, resulting in a reduction in the amount of ‘free’ Sulphur that was once deposited from the atmosphere. As a result, more than 50% of world’s Sulphur output is traded internationally, and therefore has to be stored and transported in a form that is safe, clean and commercially viable.
