2. Content Introduction Basic Process Steam reforming Water system Fuel gas system Steam system

3.  Linde’s Engineering  Hydrogen and Synthesis Gas Plant  Gas processing plant  Synthesis gas:  Mixture of gas containing primarily hydrogen, carbon monoxide and some carbon dioxide  Use in production of ammonia, methanol and synthetic natural gas  Hydrogen gas  Used in production of ammonia, methanol etc Introduction

4. Hydrogen plant in China built by Linde’s Engineering

5. 1.Hydrodesulfurization of feed stock 2.Steam reforming 3.Heat recovery from reformed and from combustion flue gas to produce process and export steam 4.Single stage adiabatic high temperature 5.CO-shift conversion 6.Final hydrogen purification by pressure swing adsorption Basic process

8.  Produce hydrogen from fuel gas and steam CH 4 +H 2 0  CO +3H 2 Steam reforming

9. Utilities involved Water System Fuel System Steam system

10.  Using DEMINERALISED WATER.  Produces high quality water free from any kind of minerals.  Uses specially-manufactured ion exchange resins which provides ion exchange site for the replacement of the mineral salts in water with water forming H+ and OH- ions. Water system

12.  Feed water is passed through two small polystyrene beds filled with ion exchange resins.  The cations present in water get exchanged with hydrogen ions in first bed.  And the anions are exchanged with hydroxyl ions, in the second bed.  These units remove Cationic ions from the water  Then the water enters through the Strong Base Anions and Anions get removed from the water stream  Mixed Bed units polishes the water, greatly reducing the conductivity level  Finally the demineralized water is then passed to the storage tank

13.  Consisting primarily of hydrogen, carbon monoxide, and some carbon dioxide.  To produce hydrogen using steam reforming method of natural gas or liquid hydrocarbons.  A device (reformer): reacts steams to high temperature produced by fossil fuel. Fuel gas system

14. Steam system Produced in steam generator, or boiler 1.Fire Tube Boiler 2.Water Tube Boiler 3.Packaged Boiler 4.Fluidized Bed (FBC) Boiler 5.Stoker Fired Boiler 6.Pulverized Fuel Boiler 7.Waste Heat Boiler

15. Steam generator:  Device used to boil a water to create steam.  heaters made with coils made of seamless tubes  feed water is preheated and evaporated during the flow  The heat is transferred to the water/steam mixture as radiant heat in the combustion chamber,  inner cylindrical tube coil and a flat tube coil forms the chamber wall and the bottom respectively.

17.  Converts low pressure steam to high pressure steam 1.Dynamic 1.Centifugal 2.Axial 2.Positive displacement 1.Reciprocating 2.Rotary Compressor

19.  In conclusion plant utility is the heart of the plant serving all kinds of life blood to the complex system. Without them, most of the equipment cannot operate.  Basically all of the systems serve almost the same purposes depending on the type of operation.  Therefore, as chemical students, utilities in plant are one of the most important basics and fundamental in plant study that should be concerned about. Conclusion
