Caffenol is a photographic alternative process whereby phenols, sodium carbonate and optionally vitamin C are used in aqueous solution as a film and print photographic developer. [ 1 ] [ 2 ] Other basic (as opposed to acidic ) chemicals can be used in place of sodium carbonate; however, sodium carbonate is the most common.

A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Line 2 baking sheets with parchment paper. In a large saucepan, melt the butter over low heat. Add the marshmallows and cook, stirring, until melted. Add the green food coloring and stir until ...
To create a SIPOC diagram, one must first map the overall process in a few steps. Then one must identify process outputs, who will receive them, and what the necessary inputs and suppliers are for each process. The final step is to share the diagram with the stakeholders to evaluate and verify the results. [5]
The process steps may be sequential in time or sequential in space along a stream of flowing or moving material; see Chemical plant. For a given amount of a feed (input) material or product (output) material, an expected amount of material can be determined at key steps in the process from empirical data and material balance calculations.

It is used when observing a physical process, to record actions as they happen, and thus get an accurate description of the process. It is used when analyzing the steps in a process, to help identify and eliminate waste—thus, it is a tool for efficiency planning. It is used when the process is mostly sequential, containing few decisions.
