SRU / Claus process burners

SRU/Claus processes are one of the most important/critical issues for installation and licensors. Starting for small, simple burners, now ICE has the capability to design, realize and test burners for all involved unites. This is also confirmed by the increased number of ICE supplies in this particular field. We also had the opportunity to install our burners in one Italian prestigious project, Tempa Rossa field, managed by Total. We consider this reference as being very important, as Total has very strict and severe specifications we succeeded in meeting.

However, not only Total recognizes ICE capabilities in this particular item, but our name is well known by all companies dealing with Claus all over the world.

Designed for critical Claus processes with pressurized and highly sour environment, these burners are proven companions to your thermal reaction furnaces, tail gas incinerators and RGG units.

The fully customized design, together with extensive NDE controls / procedures, allows for safe designs of these lethal service equipments. We can also supply CFD studies, Asme stamp and PWHT, if required by codes / customers.

High intensity design for:

  • Claus furnaces burners
  • RGG burners
  • Incinerator burners

Raw design for incinerator burners with following NOx reduction technologies:

  • Fuel staging
  • Air staging

Pilot burners, fixed or retractable igniters are also available with I.C.E. or other OEM designs.
