Pinch-Point Analysis

Pinch-Point Analysis The Role, Approach and Results of Systematic Energy Integration

With the increase in the cost of energy, the ability to optimize the use of resources, and in particular of energy, is becoming an extremely important skill for chemical engineers. Optimal integration of energy has a major role for every process unit. Systematic methods for optimal energy integration are well established in the framework of pinch - point analysis.

Industrial Application of Material Balances

Industrial Application of Material Balances Causes of Inconsistencies in Process Models and Industrial Processes

Process simulators, which initially were used for material and energy balances, are now used by process engineers for a number of important activities, including process design, process analysis, and process optimization. However, because of often very large number of equations, problems in computational efficiency and solution reliability may occur causing inconsistencies in the closing of material balances. The closing of material balance is also a big challenge in industrial processes and can help to determine faulty sensors.

Process simulation in process design

Process simulation in process design Overview of practical design problems that can be solved with process simulation

Process design is an activity that brings the industrial process from idea to reality! Before the process design can be started, the problem must be formulated and goals of the product defined. After this step is done, further activity goes to analysis and the definition of the process flowsheet that will be constructed. Sometimes, the design goal might be to make a choice whether to build a new process or to reconstruct the existing one.
