Indirect cooling for air cooling equipment to "relieve the heat"

The recent continuous high temperature has brought challenges to the safe and efficient operation of some cold exchange equipment

It is understood that the dry air cooler of the diesel product of the diesel hydrotreating unit of the plant has a high temperature of the medium after cooling, reaching the upper limit of the index (50°C) at the highest, and the light components are easily gasified, which seriously threatens the safe and stable operation of the downstream tank farm

"The principle of the new technology is to use the water in the pre-cooling wall to cool the air flowing through the tube bundle, which indirectly achieves the effect of cooling

During the renovation, on the one hand, the team communicated with the equipment manufacturers many times to speed up the production speed; on the other hand, before the equipment arrived at the factory, the construction participants were organized in advance to familiarize themselves with the installation process and installation points, and the construction was carried out immediately after the equipment arrived at the factory.
