Sulfur Granules

Sulfur is mostly produced in refineries as a by-product and used mainly to produce sulfuric acid which is widely used in the manufacture of phosphate fertilizers and also used to make detergents, plastics and other products. These products are manufactured with high quality sulfur granules and pellets as raw material. We are engaged in an on-going project of offering high quality granular sulfur and intend to position ourselves in the industry as a manufacturer, exporter and supplier.

Process Description

Liquid sulfur stored in a sulfur pit is transferred by sulfur pumps to the pastillation unit in which it enters the feeding bar and is injected onto a moving steel belt cooler through the holes on a perforated rotor.

Synchronizing of the steel belt cooler speed with the rotor is one of the most important factors affecting the shape of the pastilles and needs to be set precisely at production time to ensure a uniform product shape. When properly synchronized, the injected sulfur pastilles form hemispherical shapes as they cool and solidify while moving along the steel belt cooler. The temperature of the steel belt cooler is maintained by controlling the temperature and flow rate of water that is sprayed onto the underside of the belt. This water absorbs the heat from the molten sulfur and then goes to a cooling tower before it is stored in a water tank for re-use at the belt cooler.

Uses of Sulfur

Sulfur is considered as a fourth macronutrient along with nitrogen, phosphorus, and potassium in agriculture industry. Sulfur has various functions in plants. Some of these major roles are synthesis of proteins and chlorophyll formation. It is also essential in the synthesis of oils, especially in oil crops, and is an active component in the metabolism of nitrogen

Among end-user industries, chemicals processing segment dominates the demand for sulfur market. Sulfur is used in the vulcanization of rubber. Sulfur is added during the manufacturing process to make the rubber hard and to prevent it from melting during warmer temperatures. Sulfur is also used in the manufacture of sulfuric acid, sulfonic acid, potassium sulfate, sodium sulfate, formaldehyde, and hydrochloric acid.
