Title:
HEAVY HYDROCARBON REMOVAL METHOD
Document Type and Number:
Japanese Patent JP2019162627
Kind Code:
A
Abstract:
To provide a method for removing heavy hydrocarbon from natural gas flow while improving process efficiency.SOLUTION: In a method for removing heavy hydrocarbon from natural gas flow, C+hydrocarbon is adsorbed from natural gas flow, product gas flow having methane of higher concentration and having C+hydrocarbon of lower concentration than the natural gas flow is produced, an adsorbent bed in a PSA unit is reproduced according to pressure swing adsorption (PSA), gas flow containing C+hydrocarbon is formed, and gas containing C+hydrocarbon is used as fuel for heating an adsorbent bed of a heat swing adsorption (TSA) unit.SELECTED DRAWING: None
