Impact of Greenhouse Gas Legislation on Hydrogen Plant Design and Operation

摘要

Hydrogen plants represent one of the largest single sources of CO_2 emissions in a typicalrnrefinery. For this reason, improving their design and operation has become critical for energyrnproducers, even more so under a possible future CO_2 cap and trade environment.rnWith the integration of Lurgi in 2007, Air Liquide Group has acquired vital expertise in therndesign and engineering of hydrogen and syngas plants. Together, Air Liquide and Lurgi haverndeveloped innovative technologies to reduce CO_2 emissions and to improve the reliability,rnavailability, efficiency and capital cost of hydrogen plants.rnOperational excellence is a key factor in today's financial environment and CO_2 constrainedrnworld. Air Liquide and Lurgi’s team of international experts in safety, plant operations,rnengineering, research and development, with a special focus on instrumentation and control,rncontribute to the continuous improvement of these units.rnIn this paper, we will review improvements in hydrogen plant availability, efficiency and CO_2rnemission reduction including carbon capture for sequestration or enhanced oil recovery.
