Sulfur Solutions

SRU Thermal Reactor

The John Zink thermal reactor is a critical component in sulfur recovery units, designed to convert acid gases into elemental sulfur with high efficiency.

Overview

Our sulfur recovery unit (SRU) thermal reactors are engineered to operate under high-temperature conditions, ensuring optimal conversion of hydrogen sulfide (H₂S) to elemental sulfur. This conversion occurs within a sub-stoichiometric environment, facilitated by our advanced combustion technology. The thermal reactor is a cornerstone of the Claus Process, known for its reliability and performance in sulfur recovery. Its robust design prevents acid dew point corrosion, ensuring long-term operational integrity. 

Features

  • Operates at sub-stoichiometric conditions to maximize sulfur recovery.
  • High-intensity burners ensure optimal H₂S/SO₂ ratio control.
  • Minimum reaction furnace temperature exceeds 1100°C (2012°F).
  • Suitable for wide ranges of H₂S concentrations.
  • Engineered with a hot shell to prevent acid dew point corrosion.
  • High customizable turndown range based on acid gas pressure.

Benefits

  • Enhanced sulfur recovery efficiency.
  • Long-term durability due to corrosion-preventive design.
  • Adaptable to various operational demands with customizable features.
  • Reliable performance supported by our global service network.
