Frequently asked questions
I maintain distillation columns at a refinery — this ATECO or the one for process boilers?
Yes, distillation and rectification plant for oil refineries and chemical industries has this specific code. If your work instead involves process boilers, furnaces, and kilns, use 33.12.20.
I also maintain other chemical-process machinery beyond the columns — do I keep this code?
Usually not for other non-distillation chemical machinery: those fall under the special-purpose catch-all 33.12.99. This code is reserved for distillation and rectification plant only.
I service heat exchangers and pressure vessels at a chemical plant, not the columns — does this apply, or is it under metal products?
Usually yes, if they form part of the distillation or rectification plant at a refinery or chemical facility. If the item is a standalone metal tank or container, the metal-products code is 33.11.01.
