Saudi Aramco’s Berri Gas Plant recognized that ethane liquefaction is achievable within the ethane and NGL recovery turbo-expander plant by installing a new brazed aluminum heat exchanger. The objective of this exchanger is to utilize the available cryogenic conditions from the cold de-methanizer overhead and liquefy part of the ethane product with no major impact to plant operations. This initiative eliminates the existing ethane liquefaction process and increases the liquefaction rate by 25%.
