Ⅰ. Product feature and applied range
JX-4A is a low temperature sulfur scavenger with metal compound as main active component.It has high level for removing hydrogen sulfide and part of organic sulfur from LPG,satisfying ‘copper stripe corrosion’ requirements. It is also used to remove hydrogen sulfide from both gaseous and liquid streams,such as refinery gas and naphtha,to achieve complete purification for the feed.JX-4A low temperature sulfur sorbent has been applied successfully in more than 40 petrochemical plants.
