All Atmospheric Air Contains a Certain Amount of Water Vapor. Now, Think of The Atmosphere as A Giant, Slightly Damp Sponge. if We Squeeze the Sponge Very Hard, the Absorbed Water Will Drip Out. the Same Situation Also Occurs when The Air Is Compressed, Which Means that The Concentration of Water Will Increase, and This Gaseous Water Will Condense Into Liquid Water. in Order to Avoid Problems in The Compressed Air System, Wet Air Needs to Be Treated. This Is Done Using Aftercoolers and Drying Eq

Moisture Will Significantly Increase the Dew Point of Natural Gas, Causing the Gas to Inevitably Freeze in The Process of Liquefaction, Pipeline Transportation or Cryogenic Separation; It Can Also Form Hydrocarbon Hydrate Precipitation and Block Equipment and Pipelines; It Is Easier to Interact with H2 S and Co2 in Natural Gas, Causing Serious Corrosion of Pipeline Equipment. Deep Dehydration and Drying of Natural Gas Using Molecular Sieve Is the Most Widely Used and Mature Method.

Organic Solvents Play an Important Role in Modern Industry and Can Be Used in Many Fields Such as Chemical Industry, Medicine, Leather Making, Metallurgy and Electronics. Some Applications Put Forward Higher Requirements for The Purity of Organic Solvents, so It Is Necessary to Dehydrate and Purify Organic Solvents.

In the Traditional Low-Temperature Air Separation, Moisture and Co2 in The Air Will Freeze and Precipitate at Low Temperatures, Blocking Equipment and Pipelines; Hydrocarbons (especially Acetylene) Accumulate in The Air Separation Unit and Will Cause an Explosion Under Certain Conditions. Therefore, Before the Raw Air Enters the Low-Temperature Separation Process, These Impurities Need to Be Removed Through an Air Purification System Filled with Molecular Sieves.

Wastewater Has Complex Composition, Large Water Quality Changes, Deep Chroma and High Concentration, and Is Difficult to Treat. the Treatment Methods Mainly Include Oxidation, Adsorption, Membrane Separation, Flocculation, Biodegradation, Etc. Each of These Methods Has Its Own Advantages and Disadvantages, in Which Activated Carbon Can Effectively Remove the Chroma and Cod of Wastewater. Activated Carbon Treatment of Wastewater Has Been Studied at Home and Abroad, but Most of Them Are Coupled Wi

Activated Alumina Has Good Physical Properties, High Strength, Non-Toxic, and Tasteless. the Specific Surface Area of About 320 M2/g Makes the Activated Alumina Have a Large Contact Area, Thus Having a Good Ion Exchange Capacity. the Pore Volume Above Cm3/g 0.4 Makes It Have a High Adsorption Capacity, Because It Is Easy to Regenerate, Has a Long Life, and Is Relatively Cheap. Among Various Fluorine Removal Methods, It Is an Effective, Economical and Practical Method. Activated Alumina to Remove
