Hi there,

I'm working in an industry which produces most chemicals used in the process on site. I'm looking at doing a material balance on the entire chemical plant which is divided into three major processes: chlor-alkali, chlorate and chlorine dioxide via SVP; by products such as hypo and HCl. All are dependant to one another.

I have seen previous spreadsheet created by those who are no longer working there and found mistakes and have no confidence in fixing their balance due to lack of documentation on their spreadsheets (I find it difficult to read/understand other people's spreadsheets). For example, they do not consider the concentrations of the chemicals which I think is important since we do use and sell some chemicals at different strengths/concentrations.

I intend to start one from scratch but I do not know where and how to start. How detailed should I go into doing this? To separate each process or built a massive chemical balance? I've only been a Process Engineer for about 8 months, so I am seeking for all guidance and help I can get.

Thanks and regards.

Hello Cantur Cant

For help you, we require a description of the process that takes place: Type of process (PFD or P & ID), raw materials, supplies, products and byproducts. Also any information relevant to the required target.

For the balance, is required to apply the laws of conservation of mass and energy:
Input - Output = Accumulate

I think that will be useful.

Good luck
