Seeking an introduction to chemical process towers
Thread Content
May I ask what types of towers are there in the chemical industry? In what situations are they used? I’m new to this field and not very knowledgeable; I only know about sieve tray towers and packed tower. Fillers also seem to come in many types, such as metals, ceramics, plastics, etc. I wonder in what situations they are used. How are rings such as Lassie rings and Bower rings named?
Column types are generally divided into tray columns and packed columns. There are many types of tray columns, including sieve tray columns, guided sieve tray columns, vertical sieve tray columns, floating valve columns, guided floating valve columns, foam columns, jet columns, bubble cap columns, DJ columns, etc. Packed materials come in a wide variety; based on their installation method, they are usually classified as structured packing and random packing. Structured packing includes plate corrugated packing, wire mesh corrugated packing, and perforated corrugated packing, while random packing includes Pall rings, rectangular saddle rings, Intertek rings, Hale rings, Lassie rings, stepped rings, Taylor flower rings, and flat rings.
Towers generally serve a separation function, such as distillation towers and desulfurization towers； There are also those that react ； A few others have other functions. A heat exchanger is a device for heat exchange, used to transfer heat from one place to another. Towers and heat exchangers are the most commonly used equipment in chemical production
