Large Heat Pump brings heat from the ocean to a volcanic island

Johnson Controls delivered a large heat pump system with Vahterus heat exchangers to boost a district heating system that formerly extracted heat from fresh lava on a volcanic island near the southern coast of Iceland. The lava temperature has been reduced over the last few decades and the volcanic heat could only be utilized for ten years shortly after volcanic eruption that created havoc in the island back in 1973.

Petrochemical picks Plate & Shell over Shell & Tube for critical process application

Petrochemical companies tend to be wary of adopting unfamiliar technologies, and Sasol is no exception.

The urgency of implementation, and the lack of plot space, meant that some extraordinary measures had to be applied, and so the normal route of a column with an overhead condenser, reflux drum and reflux pumps could not be accommodated. Instead, the column was fitted with an internal overhead condenser and reflux drum with gravity reflux.
