  • Economics of a global strategy for reduction of carbon emissions

    The evolution of natural systems that feed and sustain human populations, and indeed the evolution of modern society, has occurred in the context of a moderate and stable climate. Therefore, recent trends in climate change, most likely caused by increasing concentrations of carbon dioxide and other radiative trace gases in the atmosphere, and the expected consequent global warming, are now a ...

  • Applying Kuznets theory to the analysis of relation between the economic development and greenhouse gas emission

    Proceeding from the empirical data analysis carried out for Ukraine and 37 other European countries, the author has traced a quadratic relation between the greenhouse gases emission level (at the example of CO2) and the economic development. The analysis focused on researching the possibility and reasonability of applying Kuznets theory to solving the modern environmental and economic issues of ...

  • Cycle chemistry pH measurement

    pH measurement in high purity water has met with variable success. The high resistivity of pure water, the vulnerability to contamination, the variability of reference electrodes and additional temperature effects converge to make tins a particularly challenging measurement. Overcoming these obstacles requires a thorough understanding of the potential problems and their systematic solution. ...

  • Conductivity Measurement in high purity water samples below 10 microsiems/cm

    High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...

  • Early Ethylene Glycol Leak Detection in Power Plant Steam Condensate Is Essential

    Fossil fuel and nuclear power plants use heat exchangers to condense process steam back into liquid form. A heat exchanger works by transferring heat from one medium (steam) to another medium (air, water, or ethylene glycol). Many newer, closed cooling water system, power plants use ethylene glycol use ethylene glycol (C2 H6 O2 ) as a heat transfer fluid because of its high-heat transfer ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • N2O, CH4 and CO2 emissions from seasonal tropical rainforests and a rubber plantation in Southwest China

    Abstract  The main focus of this study was to evaluate the effects of soil moisture and temperature on temporal variation of N2O, CO2 and CH4 soil-atmosphere exchange at a primary seasonal tropical rainforest (PF) site in Southwest China and to compare these fluxes with fluxes from a secondary forest (SF) and a rubber plantation (RP) site. Agroforestry systems, such as rubber plantations, are ...

  • Do You Need a Boiler Feedwater Treatment System for Your Plant?

    If you use an industrial boiler to create energy with steam, chances are you need some sort of boiler feedwater treatment system. But why? We know that natural water sources carry impurities that can cause harmful deposits, carryover, and corrosion in your boiler system. We also know that the higher the pressure your boiler runs at, the more pure your water source needs to be. ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Time to come clean on energy subsidies?

    By Elisa Wood    What you don’t know will hurt you. That’s the message in Michael Lewis’ new book, “The Big Short,” which traces today’s worldwide economic downturn to a single problem: the secretive nature of prices in the subprime mortgage bond markets.   What’s this got to do with energy? Our industry has its own opaque ...

  • Enhanced Bioremediation

    Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...

  • Pemex Refinery Decommissioning

    The Problem The decision by PEMEX to close their "La Nogalera" petroleum storage facility in Guadalajara, Mexico, involved the demolition of the facility's large storage tanks. Before demolition, the tanks had to be cleaned and all traces of petroleum had to be removed from the tanks. All tanks were pressure washed prior to demolition creating a large volume (9,035 m3) of contaminated wash ...
