The removal of solids from molten sulphur is generally done by pressure leaf filters. For over 60 years amafilter – LFC Lochem (Filtration Group Process Systems) designs, engineers and manufactures pressure leaf filters for the filtration of molten sulphur. Over the years over 15,000 pressure leaf filters have been delivered in various industries to customers worldwide.
In molten sulphur filtration amafilter – LFC Lochem is the undisputed market leader. With our extensive experience we are able to optimize your total process performance.
Impurities have a negative impact on a trouble-free continuous production of sulphuric acid.
When the catalyst in the burner / converter is progressively polluted by impurities the pressure drop will increase quickly and which will cause shorter operating cycles. Shorter operating cycles result in longer downtime, lower production capacity and higher production costs.
A similar problem is faced in the production of carbon disulphide, in which process reactor tubes are susceptible to blockage by dirt with the same end result.
The elemental sulphur needs to be filtered from impurities that can be present in the molten sulphur. The impurities are ash, dust and organic particles.
Filtration of molten sulphur is the best solution to lower the maintenance interval of the Sulphur burners, catalyst beds, and pipe reactors significantly from 3-6 months to 2 years.
Sulphur filters can be found in the following industries:
- Fertilizer industry
- Sulphuric and phosphoric acid industry
- Oil refinery industry
- Mining industry
