Iron Sponge Process - an overview | ScienceDirect Topics

James G. Speight Ph.D., D.Sc., in Natural Gas (Second Edition), 2019 8.5.1 Iron sponge process. An example of a hydrogen sulfide scavenger process is the iron sponge process (also called the dry box process), which is the oldest and still the most widely used batch process for sweetening of natural gas and natural gas liquids (Anerousis and Whitman, 1984).

Flowchart - Process Flow Charts, Templates, How To, and More

Flow Chart Symbols. You'll notice that the flowchart has different shapes. In this case, there are two shapes: those with rounded ends represent the start and end points of the process and rectangles are used to show the interim steps. These shapes are known as flowchart symbols. There are dozens of symbols that can be used in a flowchart.

Iron ore | BHP

In 2020, we produced around 280 million tonnes of iron ore. That's enough to make the steel for more than 3,300 Sydney Harbour Bridges.

INTRODUCTION TO SHEET METAL FORMING PROCESSES

In sheet metal forming practice, we distinguish five basic modes of deformation: • STRETCHING: The material is expanded in both directions. This mode of deformation is found mostly on smooth bottoms of shallow parts and in hydroforming processes. • DRAWING: This mode is typical the material flow from the flange towards the

Extraction of Iron | Metallurgy | Blast Furnace and Reactions

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
