Title:
METHOD AND DEVICE FOR SEPARATING A FEED STREAM USING RADIATION DETECTORS
Document Type and Number:
WIPO Patent Application WO/2015/084496
Kind Code:
A3
Abstract:
The present disclosure provides a method for separating a feed stream in a distillation tower. The method may include forming solids in a controlled freeze zone section of the distillation tower; emitting radiation from a first radiation source in the controlled freeze zone section while the controlled freeze zone section forms no solids; detecting radiation emitted by the first radiation source as a first radiation level; detecting radiation emitted by the first radiation source as a second radiation level after detecting the first radiation level; and determining whether the solids adhered to at least one of on and around a first mechanical component included in the controlled freeze zone section based on the first radiation level and the second radiation level.
