Abstract

A tube in tube continuous glass lined metal reactor includes: concentric tubular segments; (a) outer glass lined tube and (b) an inner glass lined segment disposed in the outer glass lined tube, defining thereby an intermediate glass lined region between the inner segment and the outer tube.

First claim

The invention claimed is:

1. A tube in tube type continuous glass-lined metal reactor, comprising:
a) an outer glass lined segment;
b) an inner glass lined segment disposed in the outer glass lined segment, thereby defining an intermediate region between the inner glass lined segment and the outer glass lined segment,
wherein reactant flows through the intermediate region and a heat transfer fluid flows through regions other than the intermediate region between the outer glass lined segment and the inner glass lined segment; and,
a port that assembles said inner glass-lined segment with said outer glass lined segment, said port comprising one or more openings for single point or multi point feeding, and a member with glass lined inner surfaces connected to the inner glass lined segment and the outer glass lined segment.

2. The tube in tube type continuous glass-lined metal reactor as claimed in claim 1 , wherein the outer glass lined segment has a tubular construction, comprising:
an outer wall and
an inner wall defining a jacketed section there between and the jacketed section comprises an inlet and outlet 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 is provided with glass lining on inner surface of the inner wall.

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

5. The tube in tube type continuous glass-lined metal reactor as claimed in claim 1 , wherein the inner glass-lined segment has a tubular construction comprising an outer tube and a straight inner tube being inserted in the outer tube 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 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 m 2 /m 3 , 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.

9. The corrosion resistant, tube in tube in tube continuous glass-lined metal reactor as claimed in claim 1 , wherein the port 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.
