One other type of reactor is worth mentioning at this time. A batch reactor is one that has no flow in or out; i.e., Q = 0. Batch reactors are virtually always assumed to be well-mixed. Webreactor, Gibbs reactor, absorption tower, heat exchangers, condensers, separators, pumps, compressors and mixers are designed on flow sheet diagram using Chemcad software. Mass balances and energy balances of Chemcad models were compared with bachelor thesis work and their differences and similarities were discussed in detail.
