Amine treatment & Sulphur recovery processes are integral to almost every oil refinery in the world.  Environmental restrictions on the release of Sulphur to the atmosphere are strictly enforced therefore it is essential to minimise sulphur discharge whilst maximising the oil output.
Plant relocation is a costs effective alternative to building new and expensive equipment.  As you can see with this example of a Sulphur processing plant where components are easily reconstituted back to a fully functioning process .
