Chart’s focus is on hydrocarbon processing applications including liquefied natural gas (LNG), nitrogen rejection, natural gas liquid recovery and other specialty cryogenic separation and recovery systems associated with natural gas and petrochemical gathering and processing.

Natural Gas Processing

Shale gas and previously stranded reserves will have a much bigger stake in the overall supply picture.

Chart’s natural gas processing technology is centered on nitrogen rejection units, the monetization of low btu gas reserves and increased revenue facilitation through systems that integrate natural gas liquids (NGL) and helium recovery, and is perfectly pitched to support these worldwide developments.

Petrochemical Processing

Cryogenic processing featuring Chart’s brazed aluminum heat exchangers and cold box systems is an integral stage in propane dehydrogenation, hydrogen recovery and the production of ethylene and ammonia.

Ethylene is the most produced organic compound in the world and is used as a building block for hundreds of everyday products, most notably those manufactured from polyethylene, the manufacture of which consumes over 50% of the ethylene supplied worldwide.

Chart designed and built brazed aluminum heat exchangers and cold boxes are essential to the cracking process and we provide optimized, tailored solutions for all major licensed ethylene processes.

Propane Dehydrogenation

Propane dehydrogenation (PDH) is a key processing step in the on-purpose production of propylene from propane feedstock. 

Chart is a preferred, pre-qualified supplier for both Uhde and UOP propane dehydrogenation processes. Our expertise is in the separation system with Chart taking responsibility for the complete engineering and fabrication package. Our overall scope covers process design and optimisation, detailed engineering and specification and critical equipment, including in-house manufacture of brazed aluminum heat exchangers, pressure vessels and cold box.

Basic package scope:

  • Brazed aluminum heat exchangers and cold box module
  • Expander, generator and lube oil package
  • Liquid product tank and pumps
  • Process and utility piping, instrumentation, control valves and electrical installation

Chart has also developed its own proprietary and patented design for the UOP process which offers improved overall recovery.

For customers not requiring an integrated system, Chart can also offer the brazed aluminum heat exchangers or complete cold box package separately.
