specific exergy Consumption as an index for Steam extraction scheme selection for co 2 capture systems in coal fired power plants
Greenhouse Gases-Science and Technology, 2016Co-Authors: Kefang Zhang, Zhongliang Liu, Zhaoliang WangAbstract:In coal‐fired power plants, Steam is extracted from Steam turbine to supply the regeneration heat for chemical absorption carbon capture. This research analyses the Steam and heat Consumption of a CO 2 capture system for different extracted Steam, as well as the influences of different extracted Steam on electricity production and power plant electric efficiency. Results show that specific Steam Consumption and specific heat Consumption, which only reveal the quantity of the Steam Consumption, could not be used for evaluating the true energy savings of different Steam extraction methods. Specific exergy Consumption of the extracted Steam (SEXCS), which focuses on both the quantity and quality of energy, is proposed and used as a main comprehensive evaluation index in the CO 2 capture system. Compared with specific Steam Consumption and specific heat Consumption, SEXCS can better evaluate the true energy saving of the different extracted Steam. Compared with plant electric efficiency and specific primary energy Consumption for carbon avoided (SPECCA), SEXCS is both simple in calculation and easy in acquiring the required data. SEXCS is thus recommended to be used as an important index for selection of Steam extraction schemes for CO 2 capture systems. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd

Low-cost Steam Consumption control system for batch pulp cooking
Control engineering practice, 2017Co-Authors: Stanko Strmčnik, Janko Petrovčič, Nadja Hvala, A BitencAbstract:In batch pulp cooking the heating Steam is used only in some phases of the technological procedure. This causes large variations in Steam flow-rate and imposes high dynamic load at the Steam generation plant. In the paper, a system for smooth Steam Consumption control is presented. It is based on three multiloop microprocessor-based controllers. The designed control structure is simple enough to be implemented as a stand-alone small-sized control system. Also, it provides a low-cost solution by eliminating the need to measure the Steam flow-rate on each digester. After the installation a reduction of 70% in Steam flow-rate variance was measured. © 1995.

Steam Consumption Control System for Batch Pulp Cooking
IFAC Proceedings Volumes, 1992Co-Authors: Janko Petrovčič, A Bitenc, Stanko StrmčnikAbstract:Abstract In batch pulp cooking the heating Steam is used only in some phases of the technological procedure. This causes very irregular total Steam Consumption. High Steam flow-rate variations impose a high dynamic load at the Steam generation plant which reduces the efficiency of the Steam generation. In this contribution a system for Steam Consumption control is presented, which is based on the three multiloop microprocessorbased controllers. The implemented control structure consists of a set of temperature controllers, a set of “smooth”temperature set-point generators, a set of state-machine algorithms for sequential control, a Steam distribution algorithm, a simple Steam flow-rateestimation and a Steam flow-rate controller. The control structure is simple enough to allow the implementation as a stand-alone small-size control system. The lowcost solution is provided also by elimination of the need for aseparate Steam flow-rate measuring system for each digesterʼs heat exchanger. After the installation a reduction of 70% in Steam flow-rate variance was measured. The reduction may be adjusted by the operator as a compromise between the acceptable dynamic loading of the Steam boilerand the requested pulp production rate.

Alternative venting in Steam retorts-An approach to energy savings in thermal processing
Chemical Engineering and Processing: Process Intensification, 2013Co-Authors: M.n. Berteli, A.a. Vitali, M.i. Berto, Antonio MarsaioliAbstract:Abstract The venting operation in retorts operating under Steam pressure is an important step in the sterilization process and it aims to Steam flush the air from inside the equipment in order to ensure sterilization safety. This part of the process is short in time but intensive in Steam Consumption, and hence this study evaluated an alternative venting operation based on the use of water to displace the air, aimed at reducing this energy Consumption. The objective was to evaluate the energy Consumption in a Steam retort loaded with thermally convective and conductive products, comparing the conventional and alternative venting processes. The Steam flow rates showed that the alternative venting process reduced Steam Consumption by up to 50% as compared to conventional venting.
