  • Ethylene oxide – useful but dangerous?

    We’re proud of the fact that Analox Sensor Technology can help you monitor a wide range of gases, from carbon dioxide and carbon monoxide, to oxygen and helium. One of the more unusual gases we offer monitoring solutions for is ethylene oxide, or C2H4O as it is often known. Many people do not know what ethylene oxide is, and we have seen a lot of Google searches where people ...

  • The Elimination of Ethylene in Domestic Refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Eliminating ethylene from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

  • Transprotekt Ethylene Filters

    Bioconservacion's ethylene filters have a new look! Recently Bioconservacion changed the appearance of its Transprotekt filters for ethylene absorption in order to make identifying them easier at all times, from the point of origin to the destination. The new filters have colour coding so that the type of filtration granule being used can be readily ...

  • Process analytics in ethylene oxide and ethylene glycol plants – Case Study

    Perfect solutions from Siemens Process Analytics Ethylene Oxide (EO) Ethylene oxide, C2H4O, under normal conditions, is a colorless, flammable gas. It is very toxic and carcinogen. Industrial production started in 1925 using the chlorohydrin process and was improved in 1931 by introducing the much more economic direct catalytic oxidation method. Currently, ...

  • Ethylene Removal: Reduce Wasting Food

    ETHYLENE REMOVAL: Reduction of fruit and vegetable waste throughout the distribution chain  Approximately one-third of the worldwide production of foods for human consumption is lost or squandered, equivalent to some 1,300 million tonnes each year.    This means that enormous ...

  • Ethylene Plant Treatment Hydrocarbon Engineering

    Ethylene is the most commonly produced petrochemical product. The bulk of annual commercial ethylene production is based on thermal cracking of hydrocarbon feedstocks with steam. Usual raw materials for pyrolysis are refinery gas, liquid petroleum gas (LPG), natural gas liquids (NGL), naphtha or gas oil. The production of ethylene is a very complex process, including cracking, cooling, ...

  • Ethylene removal through oxidation versus Ozone

    Fruit constantly emits ethylene inside the chambers. To efficiently reduce the concentration of ethylene in these spaces, it needs to be eliminated at a speed that is faster than the production ratio of the fruit. This is achieved when the airflow that passes through the machines in one hour is equal to the volume of the chamber.   Depending on the chamber's volume, Bioconservacion ...

  • Greenhouse gas reporting in the ethylene manufacturing sector

    Abstract The Greenhouse Gas (GHG) Mandatory Reporting Rule (MRR), codified in Part 98 of Title 40 of the Code of Federal Regulations, requires numerous manufacturing sectors including ethylene manufacturing plants in the U.S. to report actual GHG emissions from applicable facilities starting with reporting year 2010. This paper describes the types of GHG emission sources at ethylene ...

  • Real Time Measurments of Acetylene in Ethylene Manufacturing Process

    Keywords Tunable Diode Laser, Wavelength Modulation Spectroscopy, Analyzer, Acetylene, Ethylene, Acetylene Converter Abstract The analyzer, based on near infrared Tunable Diode Laser Absorption Spectroscopy (TDLAS), was developed for the measurement of acetylene in process streams. Measurements of acetylene were made as under laboratory conditions and in ...

  • Chemical Industry: Compliance problems solved by Ethylene Oxide Scrubber at Specialty Gas Plant Chemical Industry The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation

    Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration (OSHA). Effective August 21, 1984, the OSHA standard for EtO limited exposure to a 1 ppm, eight-hour time weighted average. Ethylene ...

  • ENVI-Carb Plus for the Extraction of Propylene Glycol and Ethylene Glycol from Water

    ENVI-Carb Plus reversible cartridges were able to extract both propylene and ethylene glycol from water, and the method was demonstrated to be both quantitative and reproducible. Elution was achieved with a combination of organic solvents, offering further options for GC analysis such as sample concentration or solvent exchange. Direct injection of the elution solvent offered an improvement in ...

  • Ethylene Production – A Tale of Explosive Growth and Air Quality Compliance

    ALL4’s Oil and Gas Sector Initiative was conceived in response to the renewal of the domestic oil and gas industry, associated primarily with the use of hydraulic fracturing (or fracking) and horizontal drilling in shale formations (e.g., Marcellus, Haynesville, Bakken, Eagle Ford) and the impact of greatly expanded oil and gas production on ...

  • 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 ...

  • Ethylene Removal in Cold Storage: Ozone versus Potassium Permanganate

    The preservation of fruit and vegetables in cold storage is currently an indispensable fact, although the cold in itself does not resolve the problem of preservation. Ethylene is a gas that is produced naturally by vegetable tissues. It acts as a vegetable hormone and principally controls the processes of ripening and senescence. Ethylene accumulates in low concentrations in areas ...

  • Oil and gas industry process analytics in ethylene production plants – Case Study

    Ethylene is the largest volume industrially produced organic material and its majority is used in the production of polymers and derivatives. Between a variety of processes the thermal cracking of hydrocarbons in the presence of steam (steam cracker) is mostly used. Regardless of the process type, all plants require process analytical equipment to collect reliable and accurate process data for ...

  • Nickel adsorption onto polyurethane ethylene and vinyl acetate sorbents

    The present study was conducted to appraise the efficiencies of polyurethane ethylene sorbent (PES) and vinyl acetate sorbent (VAS) for nickel (Ni) adsorption. Process variables, i.e. Ni(II) ions initial concentration, pH, contact time and adsorbent dosage were optimized by response surface methodology (RSM) approach. The Ni(II) adsorption was fitted to the kinetic models (pseudo-first-order ...
