Images are produced from the best available original document. Executive Summary The production processes for the top 50 U. S. commodity chemicals waste energy, generate unwanted byproducts, and require more than a stoichiometric amount of feedstocks. Pacific Northwest Laboratorya has quantified this impact on energy, environment, and economics for the catalytically produced commodity chemicals. An. excess of 0.83 quads of energy per year in combined process and feedstock energy is required. The major component, approximately 54%, results from low per-pass yields and the subsequent separation and recycle of unreacted feedstocks. Furthermore, the production processes, either directly or through downstream waste treatment steps, release more than 20 billion pounds of carbon dioxide per year to the environment. The cost of the wasted feedstock exceeds 2 billion dollars per year. Process limitations resulting ‘from unselective catalysis and unfavorable reaction thermodynamic constraints are the major contributors to this waste. Advanced process concepts that address these problems in an integrated manner are needed to improve process efficiency, which would reduce energy and raw material consumption, and the generation of unwanted byproducts.

  • Piratox Sheet N5 Suffocating Agents and Phosphine
    Edition of October 2011 Piratox sheet #5: "Suffocating agents and phosphine Indicative list of concerned agents: Toxic compounds with suffocating action - Phosgene (CAS number: 75-44-5) - Chlorine (CAS number: 7782-50-5) - Methyl isocyanate (CAS number: 624-83-9) - But also: o Ammonia (CAS number: 7664-41-7) o Diphosgene or surpalite (CAS number: 503-38-8) o Chloropicrin (CAS number: 76-06-2) o Fluorine (CAS number: 7782-41-4) o Perfluoroisobutylene (CAS number: 382-21-8) o Fumigants o Marketed industrial and domestic products - Phosphine or PH3 or Hydrogen Phosphide (CAS number: 7803-51-2). ! Key points not to forget The 1st emergency step is the extraction of victims from the hazard area: rescuers must possess suitable breathing and eye protection. At ambient temperature (20°C) most suffocating agents are gases that penetrate the body via the respiratory route. They are thus poorly or non-persistent, frequently limiting victim decontamination needs to simple undressing. Most suffocating agents are heavier than air. They affect the respiratory system: glottis, bronchi, alveoli and cause eye damage. In pre-hospital settings, avoid any physical exertion that could promote the onset of pulmonary oedema. In general, the shorter the symptom onset time, the more serious the intoxication and the more severe the symptoms. Treatment is symptomatic only. All symptomatic choking gas victims must encouraged to rest, in a sitting position, under oxygen. The duration of surveillance for symptomatic subjects is of at least 12 to 24 hours. For Phosphine (PH3): o victims must be undressed and showered; o toxicity is respiratory, cardiac, renal and neurological; o subjects having inhaled PH3 and presenting with significant initial manifestations shall be monitored in the hospital for 48 to 72 hours, due to the risk of delayed acute pulmonary oedema.

  • Organic Commodity Chemicals from Biomass
    CHAPTER 13 Organic Commodity Chemicals from Biomass I. INTRODUCTION Biomass is utilized worldwide as a source of many naturally occurring and some synthetic specialty chemicals and cellulosic and starchy polymers. High- value, low-volume products, including many flavorings, drugs, fragrances, dyes, oils, waxes, tannins, resins, gums, rubbers, pesticides, and specialty polymers, are commercially extracted from or produced by conversion of biomass feedstocks. However, biomass conversion to commodity chemicals, which includes the vast majority of commercial organic chemicals, polymers, and plastics, is used to only a limited extent. This was not the case up to the early 1900s. Chars, methanol, acetic acid, acetone, and several pyroligneous chemicals were manufactured by pyrolysis of hardwoods (Chapter 8). The naval stores industry relied upon softwoods as sources of turpentines, terpenes, rosins, pitches, and tars (Chapter 10). The fermentation of sugars and starches supplied large amounts of ethanol, acetone, butanol, and other organic chemi- cals (Chapter 11). Biomass was the primary source of organic chemicals up to the mid- to late 1800s when the fossil fuel era began, and was then gradually displaced by 495 496 Organic Commodity Chemicals from Biomass fossil raw materials as the preferred feedstock for most organic commodities. Aromatic chemicals began to be manufactured in commercial quantities as a by-product of coal coking and pyrolysis processes in the late 1800s. The production of liquid hydrocarbon fuels and organic chemicals by the destruc- tive hydrogenation of coal (Bergius process) began in Germany during World War I. The petrochemical industry started in 1917 when propylene in cracked refinery streams was used to manufacture isopropyl alcohol by direct hydration.

  • Toxic Exposures Kathy L
    8 MODULE 8 Toxic Exposures Kathy L. Leham-Huskamp / William J. Keenan / Anthony J. Scalzo / Shan Yin 8 Toxic Exposures Kathy L. Lehman-Huskamp, MD William J. Keenan, MD Anthony J. Scalzo, MD Shan Yin, MD InTrODUcTIOn The first large-scale production of chemical and biological weapons occurred during the 20th century. World War I introduced the use of toxic gases such as chlorine, cyanide, an arsine as a means of chemical warfare. With recent events, such as the airplane attacks on the World Trade Center in New York City, people have become increasingly fearful of potential large-scale terrorist attacks. Consequently, there has been a heightened interest in disaster preparedness especially involving chemical and biological agents. The U.S. Federal Emergency Management Agency (FEMA) recommends an "all-hazards" approach to emergency planning. This means creating a simultaneous plan for intentional terrorist events as well as for the more likely unintentional public health emergencies, such as earthquakes, floods, hazardous chemical spills, and infectious outbreaks. Most large-scale hazardous exposures are determined by the type of major industries that exist and/or the susceptibility to different types of natural disasters in a given area. For example, in 1984 one of the greatest man-made disasters of all times occurred in Bhopal, India, when a Union Carbide pesticide plant released tons of methylisocyanate gas over a populated area, killing scores of thousands and injuring well over 250,000 individuals. The 2011 earthquake and tsunami in Japan demonstrated the vulnerability of nuclear power stations to natural disasters and the need to prepare for possible widespread nuclear contamination and radiation exposure.
