  • Separation of CF4/N2, C2F6/N2, and SF6/N2 Mixtures in

    The capture and separation of CF4, C2F6, and SF6 and their mixtures containing nitrogen is a challenging process. To solve this, we propose the use of saccharose coke-based carbons as membranes for the adsorption and separation of these gases. By means of advanced techniques of Monte Carlo and molecular dynamics simulations, we have studied the adsorption and diffusion of CF4, C2F6, and SF6 as

  • Pure SF6 and SF6−N2 Mixture Gas Hydrates Equilibrium and

    Sulfur hexafluoride (SF6), whether pure or mixed with inexpensive inert gas, has been widely used in a variety of industrial processes, but it is one of the most potent greenhouse gases. For this reason, it is necessary to separate and/or collect it from waste gas streams. In this study, we investigated the pure SF6 and SF6−N2 mixture gas hydrates formation equilibrium as well as the gas

    What Is A Pesticide device?Recognizing A Device by Reading The LabelClaims on Device Labels Or AdvertisingOther Information About Regulating Pesticide DevicesExamples of Regulated Pesticide DevicesExamples of Devices That EPA Does Not RegulateState Regulation of DevicesPesticides are commonly thought of as chemicals. But we also have a role in regulating devices used to control pests. How a device might be regulated, however, depends on the devicespecific design and function and whether it is used with a pesticide. A pesticide device is: 1. An instrument or contrivance (other than a firearm) that is used to destroy, repel, trap or mitigate (lessen the severity of) any pest such as insects, weeds, rodents, certain other animals, birds, mold/mildew, bacter...
