EI&C planning, automation technology and switchgear construction for carbon monoxide/hydrogen production plants

Project description

Technical gases, with their specific properties, are used in many parts of the chemical and pharmaceutical industries in production, quality assurance, research, distribution and disposal. This requires large quantities of technical gases.
SembCorp Utilities (SCU) opted for German know-how for its site in the Jurong Islands (Singapore), and ordered a complete turnkey CO generation plant from a leading German company.
The customer-oriented supply concept integrates the plant directly into the local industrial network and thus connects directly with the supply equipment and user facilities. The highest standards of safety and reliability are also observed. Hydrocarbon-containing natural gas is used as the feedstock. An endothermic reforming process initially produces a mixture of H2 and CO called “syngas”. Carbon dioxide is chemically absorbed from the syngas/flue gas mixture by an alkaline solution (MEA) in absorber stages, and separated from the liquid fraction by a stripper, thus being recycled back into the process. Using two downstream semi-permeable membrane stages, the synthesis gas is now converted into CO of the highest purity.
