Taking steps to achieve zero sulphur emissions with COOL Separations

Comprimo, our sulphur technology business, has acquired the rights to license the Eutectic Freeze Crystallization (EFC) Technology from COOL Separations.

EFC produces clean water from industrial wastewater that can be reused on site. It reduces refiners’ costs and environmental footprint by providing low-temperature crystallization-based solutions for the separation of water and salts or heat-sensitive materials. Compared to alternative separations technologies, this provides refiners with a more energy-efficient path.

When an EFC unit is combined with Comprimo’s desulphurization technologies (SUPERCLAUS® or EUROCLAUS® with a caustic scrubber), this process eliminates gaseous and liquid sulphur emissions from the scrubber effluent and provides clean reusable water. In addition to treating this highly contaminated effluent to recover water, the process also produces sellable salt, which can be used as a potential raw material for fertilizer industries.

“Our partnership with COOL Separations means we can help our customers not only to meet their emissions targets and reduce their capital and operational costs, but also to encourage the reuse of water in industrial processes. This brings us one step closer to delivering a more sustainable world,” said Frank Scheel, Senior Vice President, Comprimo.

“Comprimo is the global leader when it comes to innovative solutions in sulphur recovery. We are pleased that EFC technology from COOL Separations combined with Comprimo’s sulphur recovery processes can offer refiners even more from a water recovery and emissions perspective. This collaboration also endorses the viability of the EFC process under the stringent environment of oil refiners,” said Rob van der Meij, Chief Executive Officer, COOL Separations
