Gases such as HCl gas are dissolved in water in many chemical processes, particularly to store it, purify it or simply to use it in chemical reactions. This operation is called absorption which is an exothermic reaction. Hydrogen fluoride and hydrogen bromide are also concerned by the absorption process. The absorption is often performed in combining Graphilor ®3 heat exchangers and columns. There are 2 HCl absorption processes depending on the HCl concentration in the feed gas. Process 1 - Falling Film Absorber. This process is more suitable in case of higher concentrated HCl gases. The water...

Process 2 - Adiabatic Absorption. The adiabatic absorption is applied for weak HCl gases. It takes place in Graphilor ®3 or Armylor ® columns when the phenomenon occurs without heat recovery. A Graphilor ® 3 column is used, supplied by the gas to be absorbed and the absorption water at the top. Gas and liquid flow are counter-current to ensure maximum absorption. A solution of hydrochloric acid at temperature close to boiling point, and a mix of water vapour and unabsorbed HCl, are recovered at the bottom. Two additional devices are added, namely an acid cooler and a secondary absorption device...

Production of Pure HCl Gas (AHCl) HCl Stripping and HCl Synthesis Unit The typical uses of pure HCl gas are H • igh purity silicon for solar cell or electronics applications • Organic chemistry • Various metallurgical processes There are 3 main routes to produce pure HCl, depending on the gas pressure, nature and quality of fed stream. By synthesis unit AHCl is generated by HCl gas synthesis unit. If H 2 and CL 2 are available in high quality, the synthesis of H 2 and Cl2 in Mersen synthesis unit is the most economical and reliable choice to generate AHCl gas at 2 barG max. The HCl synthesis...

Stripping System Operating under Pressure Option: AHCl Dryer A drying system can be added to any stripping systems or at the outlet of synthesis unit which will lower the moisture levels to below 5 ppm H2O in the product AHCl gas. There are different options to dry • Molecular sieve • ulfuric acid which is the commonly used S Sulfuric Acid Dryer Single or double stage systems can be provided. They all use a Brinks style demister as the final demisting element and trace amounts of H 2SO 4 will be carried over into the AHCl stream.

Acid Dilution Systems Sulfuric, Hydrofluoric, Hydrochloric Acids… Acid dilution process Our strengths The concentrated acid and dilution water are mixed under pressure in a static mixer provided by an Armylor ® dilution • Cost-efficient design tee pipe connected to the concentrated acid and dilution • Optimal material selection and reliable operation water feeds. This provides turbulent mixing of the two fluids. • Fast delivery and commissioning The dilution of acid in water generates considerable heat. The hot corrosive mixture then flows through a corrosion-resistant heat exchanger of Graphilor...
