HYSPEC™ Modular H2S Degassing System

Enersul developed the HYSPEC™ Degassing Process to quickly, effectively, and economically reduce the H2S content of liquid Sulphur to low levels, usually 10ppm or less.  The HYSPEC is a module system comprised of a series of reactors through which the process operates.  The number of reactors determines the degassing capacity of the system, resulting in truly a flexible, customizable module system that is adaptable to many different capacity requirements.

HYSPEC™ Process

Enersul's patented HYSPEC™ Degassing Process uses a gas-liquid contractor which utilizes a series of small reactors and a select catalyst to reduce the H2S content of liquid Sulphur to less than 5 ppm in a matter of minutes. The end result is improved formed product friability and increased solid Sulphur strength.
