TUBE IN TUBE CONTINUOUS GLASS-LINED REACTOR
Document Type and Number:
WIPO Patent Application WO/2015/087353
Kind Code:
A4
Abstract:
The invention disclosed herein relates to tube in tube in tube continuous glass lined metal reactor with enhanced heat transfer efficiency. Particularly, the reactor comprising three concentric tubular segments; (a) inner glass lined tube [105]; (b) intermediate glass lined tube and (c) outer glass lined tube [104]; wherein the heat transfer fluid flows in the areas of segment [104] and [105] and reactant flow between the inner and outer glass lined tubes or their annulus.

AMENDED CLAIMS

received by the International Bureau on 03 August 2015 (03.08.2015)

1 . A tube in tube type continuous glass-lined metal reactor, comprising a) an outer glass lined segment [104]; b) an inner glass lined segment [105] disposed in the outer glass lined segment [104] thereby defining an intermediate glass lined region; wherein reactant flows through the intermediate glass lined region and the heat transfer fluid flows through regions other than the intermediate region of the outer glass lined segment [104] and the inner glass lined segment [105], said inner glass-lined segment [105] is assembled with said outer glass lined segment [104] using a port [102], said port [102] possesses one or more opening for single point or multi point feeding.

2. The tube in tube type continuous glass-lined metal reactor as claimed in claim 1 , wherein the outer glass lined segment [104] has a tubular construction, comprising:

an outer wall (406) and an inner wall (408) defining a jacketed section there between and the jacketed section comprises an inlet [402] and outlet [403] for supplying heat transfer fluid.

3. The tube in tube type continuous glass-lined metal reactor as claimed in claim 2, wherein the outer glass-lined segment [104] is provided with glass lining on inner surface of the inner wall [406].

4. The tube in tube type continuous glass-lined metal reactor as claimed in claim 2, wherein the outer glass lined segment [104] comprises an inlet [401 ] and. an outlet [405] for supplying the process fluid through interior region surrounded by the inner wall [406].

5. The tube in tube type continuous glass-lined metal reactor as claimed in claim 1 , wherein the inner glass-lined segment [105] has a tubular 19

construction comprising an outer tube [504] and a straight inner tube [506] being inserted in the outer tube [504] so as to define an annular section there between.

6. The tube in tube type continuous glass-lined metal reactor as claimed in claim 5, wherein the outer surface of the outer tube of the inner glass-lined segment [105] is provided with glass lining.

7. The corrosion resistant, tube in tube in tube continuous glass-lined metal reactor as claimed in claim 1 , wherein the regions of outer glass lined segment and the inner glass lined segment through which the heat transfer fluid flows provides heat transfer area at least 300 m2/m3, for use in single phase and multiphase exothermic and endothermic reactions.

8. The corrosion resistant, tube in tube in tube continuous glass-lined metal reactor as claimed in claim 1 , wherein the reactor comprises periodic and aperiodic sequence of assembly of the outer and inner segments [104, 105].

9. The corrosion resistant, tube in tube in tube continuous glass-lined metal reactor as claimed in claim 1 , wherein the port [102] is made of metal selected from the group consisting of Mild steel, stainless steel, carbon steel and other metal alloys.

10. The corrosion resistant, tube in tube in tube continuous glass-lined metal reactor as claimed in claim 1 , wherein the reactor is fabricated in macro and micro form.
