【Daily Question No. 322】December 06, 2017: Briefly explain what material balance is The law of conservation of mass is the basis of material balance. According to this law, in a stable production process, the amount of material input should equal the sum of the amount of product produced and the losses incurred during the process; in other words, the amount entering a system equals the amount leaving that system – this is what constitutes material balance. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) For management purposes, if you need to view content from a few days ago, please access it through the summary post below. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html (Source: Haichuan Chemical Industry Forum)
The law of conservation of mass is the basis of material balance. According to this law, in a stable production process, the amount of material input should equal the sum of the amount of product produced and the amount lost during the process – this is what constitutes material balance.

A comparison between the theoretical output or usage of a product or material and its actual output or usage, with due consideration given to allowable normal variations.
The amount of material input should equal the sum of the product quantity and the losses during the process, or the amount entering a system should equal the amount leaving that system
A comparison between the actual output or consumption of a product or material, plus the amount of loss recorded, and the theoretical output or consumption, taking into account the allowable range of variation. In analytical chemistry, mass balance refers to the condition in a chemically balanced system where the total concentration of a given substance (i.e., the analytical concentration) is equal to the sum of the equilibrium concentrations of its various related forms.
The quality of the feed to the device is equal to that of the product
The sum of the outputs from all streams of the tower equals the feed rate to the tower
Feed amount = Product + By-products + Losses + Emissions
Material balance refers to the condition in a chemically balanced system where the total concentration of a given substance (i.e., the analytical concentration) is equal to the sum of the equilibrium concentrations of its various related forms.
1. A comparison between the actual output or consumption of the product or material, along with the amount of loss recorded, and the theoretical output or consumption, taking into account the allowable range of deviation. 2. In analytical chemistry, material balance refers to the condition in a chemically balanced system where the total concentration of a given substance (i.e., the analytical concentration) is equal to the sum of the equilibrium concentrations of its various related forms.
