摘要

#CMT# #/CMT# The method involves using pipes coiled around a core pipe and a mantel, which limits an outside space around the pipes. Optical signals of a fiber-optic cable are evaluated, where the fiber-optic cable is provided inside a coiled heat exchanger. A temperature measurement in the coiled heat exchanger is carried out by the evaluation of optical signals produced by Raman scattering, Brillouin scattering or scattering at Bragg grating. The optical signals of the fiber-optic cable are evaluated to coil the pipes in an inner space or on an exterior in a mantel space. #CMT#USE : #/CMT# Method for temperature measurement in a coiled heat exchanger that is utilized in a liquefied natural gas baseload system for execution of an indirect heat exchange between a hydrocarbon-containing stream i.e. natural gas, and a heating/cooling fluid (all claimed). #CMT#ADVANTAGE : #/CMT# The method measures the temperature inside the coiled heat exchanger at desired points such that energy consumption of the heat exchanger is minimized and the knowledge of the temperature distribution in the heat exchanger is increased, by the exact knowledge of the temperature distribution inside the heat exchanger.
