Refinery Operations

Refineries have unique challenges dealing with hydrogen sulfide at many points along the process.  Depending on the needs of the refinery, Heliodor Solutions systems can be placed in permanent operation, as temporary backup during turnarounds or maintenance outages of a primary H2S removal system, or as permanent backup in the event of process upsets that would cause permit violations or excess H2S in the fuel gas stream.
 

Operated successfully at major US refineries!

Some examples of potential uses for the Heliodor Solutions system within a refinery include:

• Temporary treatment of off-gas from: 

  -	Crude Unit
  -	Hydrotreater
  -	Hydrocracker
  -	Catalytic Cracking Unit
  -	Coker
  -	Platformer
  -	Saturates Gas Plant

• Tail Gas Treatment Unit temporary replacement

• Vapor Recovery Systems

• Sour Water Stripper Gas

• Wastewater Treatment Plant Off-Gas

• Polishing of amine unit gas sent to third party customers for use as fuel gas

Refinery personnel choose Heliodor Solutions because we provide:

• H2S removal consistently to 0%, no matter how high the H2S levels in the raw natural gas

• Selectivity for H2S ensuring efficient chemical consumption

• Flexibility to place systems at multiple sites within the refinery

• Inexpensive, readily available capital equipment

• Quick system design and installation

• Ability to store the HS-1500 chemical solution on site for over one year without product degradation

• Nonhazardous spent solution that allows for multiple disposal options, including on-site wastewater treatment plant or nonhazardous injection wells

• Ability to filter out elemental sulfur

Refinery operators prefer Heliodor Solutions hydrogen sulfide removal systems for several reasons, including:

• Rapid changeout of spent solution for fresh HS-1500 solution, without operator contact or heavy equipment

• Predictable run times

• Effective operation in high and low pressure environments

• Effective operation across a broad range of H2S concentrations

• Process operates unattended except for chemical changeout.

• Efficient operation over a wide temperature range

• Minimal pressure drop through the treatment vessel

• Systems can be designed for continuous operation
