Unit of the production of sulfur with crystallization unit

Unit of receiving liquid sulfur with a productivity of 26 tons/days is intended for receiving sulfur from flue gases and acidic flow from technological units due to sulfur adsorption by amine solution and further catalytic transformation into crystal sulfur.

The term of commissioning – is 2006. Technological licensor of the process on sulfur production unit (unit on sulfur extraction, including technological process of Claus) is "Tecknip KTI". 

Process of receiving liquid sulfur is designed in one technological stream and it consists of following sections: 

• section of amine regeneration (U-31); 

• section of  stripping of acidic flow (U-32);
  

• section of recovery of sulfur (U-33).
  

Unit of crystallization of liquid sulfur (U-34) with productivity of 4 t/hour allows to exploit it only in a day shift within 8 hours per day.
