  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • Exergy analysis of process heaters

    A thermodynamic analysis is proposed to investigate the entropy generation in process heaters. It is found that the major portion of the exergy losses occur in the stack. It is also found that the excess air decreases the first law efficiency while the second law efficiency remains nearly constant. Although the first law efficiency is found to be of the order of 70-90%, the second law efficiency ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • Comparative analysis of the thin-film desalination plant process

    Thin-film installations with different heating surface orientations are widely used in seawater technology. Despite the presence of various thermal schemes and the construction of evaporating devices for installations of this type, comparisons of their power output are not available. We have carried out a comparison of the thermal schemes of MSF and thin-film installations in order to determine ...

  • PHASUITE: AN AUTOMATED HAZOP ANALYSIS TOOL FOR CHEMICAL PROCESSES

    INTRODUCTION Safety is an important issue in process design and operation in chemical industry. It is even more critical for modern chemical manufacturing processes, which are either operated under extreme conditions to achieve maximum economic profit, or are highly flexible, such as the specialty chemical or pharmaceutical processes. The importance of safety analysis in process operation is ...

  • An overview of exergy analysis for chemical process industries

    Among all the industrial sectors, the chemical industry is one of the energy intensive industry with 33% share in industrial energy use. Increasing cost of raw materials, infrastructure cost and energy cost increases burden on the profit margin of the chemical sector.

  • Comparison and analysis of the expansion process in a CO2 transcritical cycle

    The isentropic and isenthalpic expansion processes in a CO2 transcritical cycle were analysed thermodynamically. It was found that the effective refrigeration capacity of the cycle with the isentropic expansion process is higher than the cycle with the isenthalpic expansion process. The increment is slightly larger than the expansion work recovered because of the transcritical nature of the ...

  • Analysis of a complex produced in the Fenton oxidation process

    The absorbances of different concentrations of Fe2+, Fe3+ and H2O2 were investigated by UV-visible spectrophotometry without separating the substances. The law of complex formation was studied by considering changes in the UV-vis spectra of mixtures of these three substances. The results show that upon eliminating the influence of the substrate, an ...

  • Risk analysis of information systems by event process chains

    Information and Communication Technology (ICT) has an important impact on critical infrastructure operation. However, the current use of risk analysis techniques has reached its limits when analysing these systems at least in practical terms. The application of extended event process chains (EPC) bypasses some of the difficulties, as they model business processes within an information system ...

  • Econometric modelling, estimation and policy analysis of oil spill processes

    This paper explores approaches to model specification suitable for empirical investigation of a stochastic oil spill model. We focus on the effects of economic incentive measures on the frequency of oil spills, spill size, and volume of oil spilled. We look into the relationships between parameters that describe the spill generation process and the enforcement effort, using data for the Black and ...
