METHOD OF SUCTION OF UNWANTED GASES FROM A CHEMICAL REACTOR

Abstract

The present invention provides a highly effective method of removal of gases from the chemical reactor (01) by use of a suction unit employed near the inlet, outlet or both ends of the chemical reactor. The suction of entrapped air from the reaction mixture helps avoid fluctuation in the temperature or pressure requirement or formation of other by-products in the reaction mixture.

Claims

1. A suction assembly attached to chemical reactor for removal of entrapped air comprises: A screen, located at junction of reactor and vacant chamber which forms a part of the suction unit; Tube having two ends, wherein one end of the tube is connected to the vacant chamber of the reactor for removal of gases; Suction unit, wherein the suction unit facilitates outlet of air from the vacant chamber through pipe.

2. A method of suction of gas from the reaction mixture wherein: the gas is passed through the screen provided at the junction of the reactor and the suction unit, wherein the liquid is re-entered into the reactor and the gas is removed or re-circulated as required; wherein the suction pressure is controlled by vacuum control valve; wherein the suction of the gas from the inlet container for gas is formed at the time of initial mixing of the reactants; wherein the suction of the gas from the outlet container for gas formed during the chemical reaction.

[0022] These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating preferred embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications.

DETAILED DESCRIPTION OF THE DRAWINGS

[0023] In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

[0024] Various embodiments of the present invention provides a suction assembly for removing unwanted gases from the reaction mixture.

[0025] The terms “suction unit” and “vacuum pump” may be used interchangeably in the following detailed description. The words “reactor”, “chemical reactor”, “assembly”, “reactor assembly” may be used interchangeably in the following detailed description. The words “reactants” “chemicals” “raw materials” may be used interchangeably in the following detailed description. The terms “thermal gradient” and “temperature gradient” may be used interchangeably in the following detailed description.

[0026] The following method is designed to provide for various applications in academia and industries requiring efficient chemical mixing and reactions of gas, liquids, solids, with or without catalysts undergoing exothermic or endothermic reactions.

[0027] The following method is designed to carry out chemical reactions in the reactor efficiently by use of suction assembly to remove the unwanted gas generated as by-product which may be caused as a result of exothermic reactions in the chemical reactor. Presence of entrapped gas in the chemical reaction mixture may cause varying of several factors such as temperature, pressure, rate of reaction, precipitation or caking of reactants or by products, etc. Thus, the entrapped gas bubbles in the reaction mixture are removed by use of a suction unit and the liquid is separated from the gas by use of a screen.

[0028] In yet another embodiment, the flexible turbulator used is designed to reduce the size of gas bubbles inside the reaction mixture in the tube and avoid coagulation of the bubbles.

[0029] In one embodiment of the present invention, suction unit is attached to the chemical reactor (1) either near the inlet end of the chemical reactor or the outlet end of the chemical reactor or both ends, if required. The suction unit is usually attached near the outlet end of the chemical reactor to remove any gases formed immediately after addition of reactants in the same chamber. The suction assembly is attached to the outlet end of the reactor in order to remove the unwanted gases formed in the reaction mixture as by-product of exothermic reaction. The rate of removal of the entrapped gases is controlled by the presence of control valves present on the tube of the suction assembly. The unwanted gas is then collected in a separate container which can be used or discarded based on requirement of the reaction.

[0030] In another embodiment of the present invention, the reaction mixture is circulated back into the reactor for further mixing and further removal of gases formed during the reaction and the process is repeated until the final product is achieved.

[0031] Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the invention with modifications. However, all such modifications are deemed to be within the scope of the claims.

[0032] It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the scope of the claims.

Advantages of the Invention

[0033] The present invention discloses an efficient method of chemical reaction by removal of unwanted gas produced as a result of chemical reaction. Removal of such unwanted gas reduces variation of temperature and pressure and risk of unwanted by products being formed in the reaction tube.
