Embodiment Construction

[0030] A first embodiment of a reaction calorimeter probe 1 generally comprises an inner tube 2 arranged to have a pumpable reaction medium flowing through the inner tube 2, for example by figure 1 and the outer tube 3 extending coaxially with the inner tube 2 at a radial distance d from the inner tube 2 . The end opening of the outer tube 3 is sealed by a sealing first cap 4 and a second cap 5 . Thus, a sealed space 6 is provided between the inner tube 2 and the outer tube 3 . This structure of the inner and outer tubes and other components therein, which will be described hereinafter, will also be referred to herein as the tubular component 15 of the reaction calorimeter probe 1 . Space 6 is set to vacuum, that is, space 6 has been evacuated to a very low pressure, preferably below 10 -6 bar, and more preferably below 10 -8 bar. In any case, the evacuation of the air should reach a pressure level in which the thermal conductivity in the space 6 is significantly reduced ...

Abstract

A reaction calorimeter probe (1) arranged for calorimetric in-situ measurement in a pumpable reaction medium, the reaction calorimeter probe comprising: an inner tube (2) arranged to flow the pumpable reaction medium through the inner tube; an outer tube (3) extending coaxially with the inner tube at a radial distance from the inner tube; a sealed space (6) between the inner tube and the outer tube, the space being arranged in a vacuum; a first temperature sensor (7) arranged at the inlet end (8) of the inner tube; a second temperature sensor (9), the second temperature sensor is arranged at an outlet end (10) of the inner pipe; a certain distance is reserved between the second temperature sensor and the first temperature sensor; wherein the first temperature sensor and the second temperature sensor are arranged in the space and in contact with an outer surface of the inner tube for measuring an absolute temperature of the inner tube, and wherein the first temperature sensor and the second temperature sensor are arranged to be able to determine the absolute temperature at a resolution better than 1 [mu] K; and a computing device connected with the first temperature sensor and the second temperature sensor, the computing device arranged to determine a first absolute temperature by the first temperature sensor, a second absolute temperature by the second temperature sensor, and a temperature difference between the first absolute temperature and the second absolute temperature.

Description

technical field [0001] The present invention relates to the field of calorimetric probes, and more particularly to a reaction calorimeter probe arranged for performing calorimetric measurements in a pumpable reaction medium, and to a reaction calorimeter probe containing a pumpable A method for continuously determining the heat production in the reactor of the fed reaction medium. Background technique [0002] Reaction calorimetry is a field generally associated with the thermal study of chemical processes applicable in the process industry. Reaction calorimeters are usually designed for 0.1 to 2 liter batch reactors with the intention that they should simulate industrial scale chemical processes. Some examples of existing commercial instruments are RC1 and HFCal (manufactured by Mettler-Toledo), Atlas and Chemisens (manufactured by Syrris, formerly Chemisens AB) and Simular (manufactured by HEL-Group). [0003] SE7415590 discloses an in situ reaction calorimeter probe hav...
