Low Sulphur Heavy Stock

Low Sulphur Heavy Stock (LSHS)

Low Sulphur Heavy Stock (LSHS) is a fuel oil specifically designed for industrial use, characterized by its low sulfur content. It is a by-product of the refining process of crude oil, often used in furnaces, boilers, and other high-temperature applications where fuel with minimal sulfur emissions is desired.

Advantages

1. Environmentally Friendly:

  • Low sulfur content reduces SOx emissions, minimizing air pollution.

2. Efficient Combustion:

  • High calorific value ensures cost-effective heat generation.

3. Less Maintenance:

  • Lower ash and deposit formation reduce equipment maintenance needs.

Disadvantages

1. Specialized Storage Requirements:

  • Requires insulated storage tanks to prevent solidification at lower temperatures.

2. Initial Heating:

  • Pre-heating may be necessary for pumping and optimal combustion.

3. Availability:

  • Limited availability compared to other fuel oils, depending on the region.

Storage and Handling

  • Temperature Control: LSHS should be stored at a temperature above its pour point (approximately 50–60°C) to maintain fluidity.
  • Storage Tanks: Insulated or heated tanks are recommended.
