VALVE TRAYS<\/h2>\n

Valve trays are mainly used in distillation plants and to optimize the thermodynamic balance<\/strong> between the liquid and gaseous phase.<\/p>\n

The trays consist of a perforated surface<\/strong> and are equipped with devices that put the two phases in contact, a zone called descending, where the liquid flow drops from the upper plate,<\/strong> and an area where the liquid passes to the lower plate.<\/p>\n

Greater liquid-vapour contact leads to better separation on each tray and thus greater column efficiency.<\/p>\n

Contact devices are mainly of the following types<\/strong>:<\/p>\n

LIQUID DISTRIBUTORS<\/h2>\n

The liquid distributors are positioned inside the process columns<\/strong> and are necessary to ensure a correct distribution of the liquid flow.<\/p>\n

In columns, a bed of structured bodies<\/strong> is often used that can facilitate the desired process.<\/p>\n

VLV sizes and manufactures these internals<\/strong> optimizing them according to the needs of the process.<\/p>\n

SUPPORT GRIDS<\/h2>\n

The support grids are usually installed inside the process columns to ensure<\/strong>, for example, structural tightness<\/strong> and to allow the flow to pass through the grids without having pressure drops.<\/p>\n

The support grids can be made in various sizes and with different types of materials and, if necessary, also with different layers of metal mesh applied to the structure.<\/strong><\/p>\n

This type of grating is customizable and generally designed according to customer specifications, without neglecting the necessary mechanical stability that these support elements must have.<\/p>\n
