This large order formed part of the sugar factory upgrade and capacity increase from 8,000 to 12,000 tbd. Reducing energy consumption is a major goal for sugar factory operators. Here it was made possible by running the new evaporators together with the existing ones.
The upgraded evaporator station will have five effects. And these are the technical details for the four evaporators from BMA: 5,000 m2 are installed as 4th effect, 4,000 m2 as effect 3A, 4,000 m2 as effect 3B and 3000 m2 as 5th effect. Now that they are installed, 4th vapour can be used to heat the VKT for A product, resulting in considerable energy savings.
The VKT has a diameter of 5,600 mm, a height of 38,000 mm and a heating surface of 3,180 m2. All parts that come into contact with the massecuite are fully made from stainless steel.
BMA later received an additional order for supply of a direct-contact condenser. This operates according to the parallel flow/counter flow principle: large parts of the vapour coming from the VKT are condensed in a parallel flow with cooling water. The uncondensed vapour together with the non-condensable gases passes into the counter flow section of the condenser (post-condensation), largely preventing vapour and non-condensable gases reaching the vacuum pumps.
