Many natural gas distributors store liquefied natural gas in order to meet peak demands. Before natural gas can be liquefied, impurities such as water and CO2 must be removed to prevent freeze ups. Although amine solutions will remove CO2 and alumina will remove water, using molecular sieves to adsorb both impurities at the same time is more cost-effective.
