DEVELOPMENT OF THE ABSORPTION PROCESS IN THE DIFFERENT INDUSTRIES

Abstract

Absorption, or gas absorption, is a unit operation used in the chemical industries to separate gases by washing or scrubbing a gas mixture with a suitable liquid. Gas absorption is usually carried out in vertical countercurrent columns The solvent is fed in at the top of the absorber, the gas mixture from the bottom. We developed the process to get high yield and high efficiency.

Claims

Absorption system for absorbing one or more constituents of a gas mixture, wherein the one or more constituents of the gas mixture are absorbed in a liquid in a liquid tank, wherein said system comprises said liquid tank, a pump and a venturi system coupled to said liquid tank and the pump, wherein the venturi system is arranged for injecting the gas mixture into the liquid in said venturi system and to inject the mixture into said liquid tank below the liquid level, wherein the liquid tank comprises an outlet to the pump and the venturi system is coupled to the liquid tank above said outlet to inject the gas mixture into the liquid in said tank above said outlet.

2. Absorption system according to claim 1, wherein the venturi system is arranged for injecting the gas mixture into the liquid in said liquid tank from the bottom of said liquid tank and further comprising a stripping system arranged for recovering the liquid in said liquid tank in a stripping operation

3. Method for absorbing one or more constituents of a gas mixture, wherein the one or more constituents of the gas mixture are absorbed in a liquid in a liquid tank, wherein said method comprises: providing an absorption system according to claim 1; providing liquid in the venturi system; injecting the gas mixture in the liquid using the venturi system.

4. Method according to claim 4, further comprising: injecting the gas mixture, injected in the liquid using the venturi system, into the liquid tank from the bottom of said liquid tank.

5. Method according to claim 4, further comprising: injecting the gas mixture, injected in the liquid using the venturi system, into the liquid tank below a liquid level in the liquid tank. recovering the liquid in said liquid tank in a stripping operation subsequent to injecting the gas mixture in the liquid using the venturi system.

6. Method according to claim 5, further comprising: injecting the gas mixture, injected in the liquid using the venturi system, into the liquid tank below a liquid level in the liquid tank. recovering the liquid in said liquid tank in a stripping operation subsequent to injecting the gas mixture in the liquid using the venturi system.

Description

DISCLOSURE OF INVENTION

[0024] Replace the absorption unit in the different industries by injection the gases in liquid by using venturi system as illustrated in the image below.

we could use the venturi system instead of absorber in the chemical, fertilizer, pollution control (using venturi system for the flue gases), petrochemical and fertilizer industries and other applications.

[0025] Control in the water pressure to control the suction force to be optimum to enable it to withdraw the gas without effect in the process

[0026] By this method we could develop the absorption unit in the industries and make a method with high mass transfer, high gas residence time and can handle high flow rate, this help in the increasing the yield and the efficiency in the different industries and make high effect in the air pollution control because with this method we could prevent more harmful gases from release to the environment.

[0027] In the flue gases, collection the co2 after this treatment and connect it by pipelines to the greenhouses, in the industries like cement, energy, waste incineration, it will affect in the climate change

[0028] Gas absorption is usually carried out in vertical countercurrent columns. The solvent is fed in at the top of the absorber, the gas mixture from the bottom. This unit has disadvantages like Poor mass transfer, Cannot handle extremely high or low flow rates and short gas residence time so we made a method to get high efficiency.

[0029] Replace the absorption unit in the different industries by injection the gases in liquid by using venturi system as illustrated in the image below.

[0030] We could use the venturi system instead of absorber in the chemical, fertilizer, pollution control (using venturi system for the flue gases), petrochemical and fertilizer industries and other applications.

[0031] For the venturis system Controlling the liquid pressure to control the suction force to be optimum to enable it to withdraw the gas without effect in the process

[0032] By this method we could develop the absorption unit in the industries and make a method with high mass transfer, high gas residence time and can handle high flow rate this help in the increasing the yield and the efficiency in the different industries and make high effect in the air pollution control because with this method we could prevent more harmful gases from release to the environment

[0033] In the flue gases, collection the co2 after this treatment and connect it by pipelines to the greenhouses, in the industries like cement, energy, waste incineration, it will affect in the climate change.

[0034] Analysis of flue gases out of incineration after the treatment by the system show the high efficiency of the system
