Isobutane butane separation consultation
Thread Content
Raw materials: a mixture of isobutane and n-butane, with a flow rate of 4 tons per hour and a n-butane content of 95% (w). Distillation separation is planned; how many tray levels are required? Tower diameter? Is a butane content of 98.5% W required for the product? The heat source is 10 kilograms of superheated steam at 250 degrees; what is the steam consumption? Top of tower cooling load or circulating water consumption?
I previously worked with DIB towers, which have 133 trays; roughly one ton of feed corresponds to one ton of steam. I’m not sure what you need high-purity n-butane for
Used as chemical raw materials. 133 floors? That’s too much, right?
130 multi-layer trays – not many. Butane has a boiling point of around 0 degrees, while isobutane has a boiling point of around -11 degrees; it is a low-temperature separation process, and without enough tray sections, effective separation cannot be achieved.
