Due to their higher efficiency of energy utilisation heat-integrated column systems have been widely used in chemical industry. However, the heat-integration leads to difficulties in startup of such columns, i.e. a long startup time and thus considerable costs will be resulted. In this work, a study consisting of modelling, simulation, optimisation and experimental verification is made for deve...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...

A modified oxygen uptake rate (OUR) test for characterizing the performance of integrated fixed-film activated sludge (IFAS) processes was developed while monitoring the startup of a full-scale demonstration facility. Data on total biofilm solids, in-basin nitrification rates, and batch nitrification rates were compared to the OUR test. The data was used to investigate dynamic changes in the ph...

Preventive maintenance is essential for every chemical production site to prevent failure and accidents, however it upsets material and utility flows inside the site and also causes production loss. In order to minimize the loss, maintenance of each plant unit has to be carefully scheduled together with considerations on site-wide material and utility balances. This will involve both production...

Startup of distillation columns is one of the most difficult operations of chemical processes. Since it often lasts a period of time, leads to off-products and costs much energy, optimization of startup operating policies for distillation columns is of great interest in process industry. Most previous studies on column startup have been restricted to theoretical investigations such as modeling,...

Influenced by decreasing product development times, early production startups, increasing ranges of variants and heightened process orientation, systematically interconnecting the development of products with the development of production systems to form an integrated unified process is becoming a priority in manufacturing companies. This constitutes a significant basis for realizing time and c...

ARIES-ST, a fusion power plant design based on the spherical tokamak concept, has many attractive features, including high beta and power density, low magnetic field, and high self-driven current. The physics basis for choosing the design plasma parameters are described with respect to MHD equilibrium and stability, current drive, and startup. Implications for the fusion power core design are h...
