What software is used to draw temperature-enthalpy diagrams in grip technology?

I have done it using Excel before. If using the grip method, AspenPINCH should work, but I haven’t used it. ASPEN PINCH system energy-saving software System energy-saving software Aspen Pinch is a computational software based on pinch technology for process synthesis and integration. It uses factory operational data or data from Aspen Plus simulations as input to design chemical plant and refinery process flows that minimize energy consumption and operating costs. Its typical functions include the following aspects: 1. Design of an integrated solution for the energy-saving renovation of old factories ； 　　2. Analysis of “bottleneck removal” for old factories to expand production capacity ； 　　3. Design analysis of energy recovery systems (e.g., heat exchanger networks) ； 　　4. Rational layout and optimized operation of utility systems (including models for heating furnaces, steam turbines, gas turbines, refrigeration systems, etc.). 　　When using this pinch technology for process design, based on the experience of some large petrochemical companies, it is generally possible to save around 20% in energy consumption during the renovation of existing plants, with a payback period of about one year ； The design of new plants can often save 30% on operating costs, while simultaneously reducing investment by 10-20%. 　　New features of ASPEN PINCH (May 1998): 1. Integration with both simulation software Aspen Plus and Pro II ； 　　2. Many improvements to the user interface, fully windowed ； 　　3. Network Pinch (automated design for technical upgrades) ； 　　4. OLE function for embedding target links ； 　　5. Graphical interface for heat and electricity users ； 　　6. Improvements have been made to help and the user manual.

Excerpt from the Aspen Chinese Reference Manual: Flash tables can be used to quickly estimate zone distributions and pinch points; these tables are very useful for heat exchangers with many streams, as zone analysis calculations take a long time. To use the flash tables for logistics, you can specify the number of flash points for logistics on the Input Flash Table page of the MHeatX model. When you specify a flash table for a stream, the MHeatX model generates a temperature-humidity diagram for that stream prior to performing regional analysis, and interpolates this diagram during the regional analysis, for streams that do not flash. On the Input Flash Table page of the MHeatX model, you can specify the total pressure drop fraction for a stream within each phase region. ASPEN PLUS uses these fractions to determine the pressure distribution during the generation of Flash Tables. English help: Use Flash Tables to estimate zone profiles and pinch points quickly. These tables are most useful for heat exchangers that have many streams, for which zone analysis calculations can take a long time. To use a Flash Table for a stream, specify the number of flash points for the stream on the MHeat*nput Flash Table sheet. When you specify a flash table for a stream, MHeatX generates a temperature-enthalpy profile of that stream before zone analysis, and interpolates that profile during zone analysis, rather than flashing the stream. You can also specify the fraction of total pressure drop in each phase region of a stream on the MHeat*nput Flash Table sheet. Aspen Plus uses these fractions to determine the pressure profile during Flash Table generation.

The process energy integration software package STAR can also be used to plot the combined curves for each individual process as well as the overall combined curve.

Reply to 2# chetec: Could you please explain how to do this using Excel? Can you provide the specific steps?

How can I move hot and cold logistics? What software can be used for this? Can ORIGIN be used?
