| LPG recovery from low-pressure gas |
Robert A Mortko and Kevin L Currence, Black & Veatch
|
2008 / Gas |
Low-pressure feed streams that were previously vented to flare or only used as fuel gas can now be economically processed, while also reducing plant carbon dioxide emissions and improving the quality of the plant fuel stream.

| Curtailing refinery CO2 through H2 plant |
Sanjib Ratan and Roland van Uffelen, Technip
|
2008 / Gas |
In addressing refinery CO2 management, some of the proven advanced solutions applied in the on-purpose hydrogen plants allow substantial CO2 curtailment through minimised 'involuntary'steam, internal heat recycle and captive integration.
