Difference between Block diagram, Flowsheet and Flow diagram

[Sinead]

I want to know the difference between Block diagram, Flowsheet and Flow diagram (in process engineering, especially in chemical engineering).

Also could anyone link me to some useful websites where I can get more details about all these?

Thanks in advance.

Some pretty good Chem Eng resources:

http://www.engineeringtoolbox.com/bfd-block-flow-diagram-d_467.html

The DOE's handbooks on drawings have a few sections on block diagrams and P&IDs:

The main difference between a block diagram, flowsheet, and flow diagram lies in their level of detail and purpose.

A block diagram is a simplified representation of a system or process, typically using blocks and arrows to show the relationship between components. It is used to provide an overview or general understanding of a system, but does not typically include specific values or measurements.

A flowsheet, on the other hand, is a more detailed diagram that shows the sequence of operations in a process. It includes specific equipment, instruments, and measurements, and is often used in process engineering to design and optimize processes.

A flow diagram is similar to a flowsheet, but it focuses more on the flow of materials or fluids through a process. It may also include information about process parameters, such as temperature or pressure, and can be used to analyze and troubleshoot a process.

In summary, a block diagram provides a high-level overview, a flowsheet shows the sequence and details of a process, and a flow diagram focuses on the flow of materials or fluids in a process.

As for websites, some useful resources for process engineering and chemical engineering include AIChE (American Institute of Chemical Engineers), ChemEngOnline, and Chemical Processing. These websites offer a wealth of information, articles, and resources on various topics related to process engineering. Additionally, many universities and colleges also have online resources and course materials available on these topics.
