A pressurized water process for bio gas cleaning is optimized by means of its exergetic efficiency. The exergy consumption of this process is a suitable measure as it weights electricity and steam consumption and considers the increase of physical and chemical exergy of the treated bio gas stream. In this paper the steps applied for modeling the process and for calculating the exergy of the streams are presented and an outlook on the optimal operation conditions is given. © Copyright 2017, AIDIC Servizi S.r.l.

How to use software effectively and efficiently in the chemical, pharmaceutical and life science industries is one of the central questions in Process Optimization. The paper shows in five examples from chemical engineering how various programs connect to a first principle process simulator through the existing interfaces. It also shows how the functionality of a process simulator can be enhanced. Through the application programming interface (CC-API), the objects are re-used beyond the boundaries of the flow sheeting program CHEMCAD. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Industrie 4.0 is a project in the high-tech strategy of the German government to promote the computerization of traditional industries such as manufacturing. Other countries have similar programs. Industrie 4.0 changes the cooperation of enterprises and the relationships of the company to its customers significantly. The company's success increasingly depends on the competence of the company to use software properly. Not only the life cycles and the understanding of quality in the software industry and in process engineering come into conflict. Software ranges from the MS-Excel spreadsheet of the individual engineer over more or less closely associated applications of all sizes through to the group-wide integrating SAP R/3. At the interfaces of software, knowledge stocks of different domains (semantics) with their standardizations and with potentially different meanings collide. In process design and development, chemical engineers use MS-Excel and process simulators to create process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), equipment data sheets and heat and mass balances. Manufacturers typically use their own programs for the design of the equipment. Starting with the basic design or the following detailed design, asset management systems network and coordinate all the crafts involved in the planning and operation of a plant across sites and across the entire life cycle of the plant. Various organizations, associations and initiatives such as Namur, Verein Deutscher Ingenieure (VDI), DEXPI, ISO 15926, CAPE-OPEN and others have begun to describe the requirements for data structures and the interchangeability of data records between CAE (Computer Aided Engineering) systems. The paper shows in four examples from chemical engineering how various programs connect to a chemical process simulator through the existing interfaces. MS-Excel plays an important role in almost all cases. From these examples, course of action for process engineering, for computer science and for management derive.

The purpose of this paper is to assess via techno-economic and environmental metrics the production of methanol (MeOH) using H2 and captured CO2 as raw materials. It evaluates the potential of this type of carbon capture and utilisation (CCU) plant on (i) the net reduction of CO2 emissions and (ii) the cost of production, in comparison with the conventional synthesis process of MeOH Europe. Process flow modelling is used to estimate the operational performance and the total purchased equipment cost; the flowsheet is implemented in CHEMCAD, and the obtained mass and energy flows are utilised as input to calculate the selected key performance indicators (KPIs). CO2-based metrics are used to assess the environmental impact. The evaluated MeOH plant produces 440ktMeOH/yr, and its configuration is the result of a heat integration process. Its specific capital cost is lower than for conventional plants. However, raw materials prices, i.e. H2 and captured CO2, do not allow such a project to be financially viable. In order to make the CCU plant financially attractive, the price of MeOH should increase in a factor of almost 2, or H2 costs should decrease almost 2.5 times, or CO2 should have a value of around 222€/t, under the assumptions of this work. The MeOH CCU-plant studied can utilise about 21.5% of the CO2 emissions of a pulverised coal (PC) power plant that produces 550MW net of electricity. The net CO2 emissions savings represent 8% of the emissions of the PC plant (mainly due to the avoidance of consuming fossil fuels as in the conventional MeOH synthesis process). The results demonstrate that there is a net but small potential for CO2 emissions reduction; assuming that such CCU plants are constructed in Europe to meet the MeOH demand growth and the quantities that are currently imported, the net CO2 emissions reduction could be of 2.71MtCO2/yr. © 2015 The Authors.
