Curve Marine is a technology company incorporated in Singapore in 2017. Several years of R&D have been invested to create deliverable solutions to meet the


Challenge of MARPOL Annex VI.

Curve Marine in 2021 has patented technologies for the efficient removal of sulphur from heavy fuel oil. The patented technologies are based on advanced extractive chemistries utilizing a novel innovative reactor design. The solution achieves sulphur removal at low temperatures and ambient pressures; reducing significantly the carbon footprint normally associated with conventional sulphur removal.

Reduced Carbon Footprint


The sulphur removal process will be accomplished via a low capital system that allows for high residuum utilization and the delivery of a stable high-quality VLSFO product. The solution is non-intrusive, residing at the end of the refinery process or alternatively as a stand-alone option in a tank-storage environment.
