To document a process flow, start by identifying the specific process you want to chart or diagram and break it down into a series of steps. Make a visual representation of these steps through a flowchart. Use different shapes and symbols to depict process steps, decision points, and connectors, then label each element properly.

A flowchart is a diagram that illustrates the steps, sequences, and decisions of a process or workflow. While there are many different types of flowcharts, a basic flowchart is the simplest form of a process map. It's a powerful tool that can be used in multiple fields for planning, visualizing, documenting, and improving processes.
We adopted the process flow chart developed by Lai and Ngu (Lai and Ngu, 2020) for the production of activated carbon using chemical/physicochemical activation method ( Fig. 7a and b). The method ...
The main objective of coal beneficiation, also known as coal washing, is to remove impurities from the raw coal, reduce the ash content and provide the user with fine and power coal. This dense medium coal preparation process flow chart is shown in Fig. 7 [21]. However, due to the lag of the offline test, the timeliness of operating performance ...
Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from runofmine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size.

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
This is a dull black coal with a higher heating value than lignite that is used primarily for generating electricity and for space heating. Most subbituminous reserves are located in Montana, Wyoming, Colorado, New Mexico, Washington and Alaska. Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal.

In this process, the air and steam flow required for gasification is sufficient to fluidize the bed of coal, char and ash. Fluidization occurs when the gasflow velocity lifts the particles and causes the gassolid mixture to flow like a fluid (Shadle et al., 2002; Crelling et al., 2005). Entrainedflow
