integrated design and simulation of chemical processes

[...]... development and design of processes Sustainability must be integrated in the design practice, primarily by minimising and recycling the waste produced in the process, and not only by end -of- pipe corrections In this respect, a systemic approach of the whole supply chain allows the designer to identify the stages of inefficient use of raw materials and energy, as well as the sources of toxic materials and pollution... optimisation criteria and the environment of constraints 3 Computer simulation is the main tool for analysis and synthesis However, the quality and efficiency of the final design depends on the capacity of the designer to integrate generic software capabilities with specialised engineering skills 4 IPD addresses both new design, as well as debottlenecking and retrofit projects The methods and tools of IPD can... should avoid hazards and unsafe reactions The process should be compact and economical in energetic consumption, but offer flexibility and ready to accept other raw materials or other specifications of products The optimal combination of so many aspects gives highly integrated processes The design of complex processes implies the availability of adequate conceptual methods and of powerful computer-based... water and solvents may be assessed well ahead the design of units Process Simulation consists mainly of material and energy balances As mentioned, during the conceptual design several alternatives are developed, from which a base-case will be selected for further refinement and optimisation Figure 1.7 Life cycle of an integrated design project 14 Chapter 1: Integrated Process Design The evolution of the... Process Design The key topic is the Sustainable Development and its implications on the design of chemical processes, as Production -Integrated Environmental Protection Integrated Process Design is described as the marriage of two types of activities: Process Synthesis - architectural design, and Process Integration - development and optimisation of subsystems in a flowsheet This distinction, although somewhat... refined and optimised A remarkabl6 feature of the systematic methods available nowadays is that these can set quasi-optimal targets well ahead the detailed sizing of the equipment The assembly of the systematic methods applied to chemical processes forms the new design paradigm designated today by Process Integration Its application relies on the intensive use of Process Simulation Combining design and simulation. .. consisted of sketching a simple but inspired flowsheet, and improving it by successive layers of refinements, up to final optimisation The experience of the designer, the expertise of the company, and the availability of pilot data were crucial Nowadays, the conceptual design of processes is becoming increasingly an applied chemical engineering science Engineers having a solid scientific background and mastering... 612 625 636 638 xiii 1 7 CASE STUDIES 17.1 Design and simulation of HDA plant 17.2 Dynamic Simulation of the HDA plant 17.3 Control of impurities in a complex plant 17.4 References APPENDICES A Estimation of basic equipment cost B Cost of utilities C Materials of construction D Saturated steam properties E Vapour pressures of some hydrocarbon F Vapour pressures of some organic components G Conversion... analysis of a design problem by means of simulation, commonly called flowsheeting This chapter presents elements of the software architecture, as well as the main integrated commercial systems Chapter 3 develops in larger extent the Steady state Flowsheeting Major topics include the description of generic flowsheeting capabilities, as degrees of freedom analysis, treatment of recycles, and use of control... the organisation of courses and design projects, at both undergraduate and postgraduate levels The Economic Evaluation of design projects is treated in Chapter 15 from the perspective of profitability analysis Chapter 16 develops some guidelines for the Selection and Sizing of Process Equipment, namely reaction vessels, separation columns, heat exchangers, and devices for the transport of fluids The last .
