AI Overview
A sulphonation plant SO₂/SO₃ converter is a catalytic reactor that oxidizes sulfur dioxide (SO₂) to sulfur trioxide (SO₃) using a vanadium pentoxide (
) catalyst, acting as the heart of sulphonation plants for producing surfactants (e.g., LABSA, SLES). It typically uses multi-bed, vertical stainless steel designs to maximize high conversion rates, often exceeding 99% efficiency through exothermic reactions.
