  • Increasing safety in waste water treatment plants – Case Study

    BP in Geel/Belgium runs the largest PTA plant in Europe. Purified Terephthalic Acid (PTA) is the preferred raw material for the most common plastic products of daily life. It serves to make polyester fibers, polyester films, PET bottle resins, and to other polyester thermoplastic products. BP produces around 30 million tones per year which is 30 % of the worlds production of PTA. The TPA ...

  • Mosaic Stadium, Regina: Home to the Roughriders and IPEX Case Study

    From the beginning the owner was interested in the use of thermoplastic piping systems for drain, waste, and ventilation (DWV), potable water and chilled water lines, but research needed to be done. After looking at price and installation-time comparisons with copper and steel pipe, the most cost-effective choice with the quickest install time was thermoplastic ...

  • Production and recovery of poly-β-hydroxybutyrate from whey degradation by azotobacter

    Poly-β hydroxyl-butyrate, (PHB) is a biodegradable thermoplastic which can be extracted from a wide range of bacteria. PHB belongs to the class of bacterial polyesters collectively called polyhydroxyalkanoates, (PHAs). PHAs have properties similar to polypropylene and are important due to their complete biodegradability, with recognised potential applications in reducing disposable waste ...

  • Solidification/Stabilization

    Introduction: As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be ...

  • Feedstock recycling from plastic and thermoset fractions of used computers (I): pyrolysis

    The increasing production of computers, the progress in their performance, and the shorter time between innovation and production has led to increasing numbers of obsolete products. It has thus become necessary to recover some materials from old computers and to protect the environment from a new type of pollution. Such recycling is difficult because of the diversity of polymeric materials used, ...

  • Real-time O2 monitoring in VCM plants using the In-situ laser gas analyzer – Case Study

    Vinyl Chloride Monomer (VCM) Vinyl Chloride Monomer is a colorless, flammable gas. It is of very great importance as feedstock in the production of polyvinyl chloride (PVC), one of the world´s most versatile thermoplastics. Originally, acetylene has been used as feedstock for VCM production but was replaced stepwise by the inexpensive ethylene. Complete changeover to almost ...

  • Deer Island Wastewater Treatment - Case Study

    The Project The Deer Island treatment plant, operated by the Massachusetts Water Resources Authority, is the public wastewater treatment facility for the city of Boston. The plant is undergoing an extensive refurbishment, replacing all of its chain and sprockets. Diversified Plastics, pre-qualified by the independent design engineering firm, earned the award of an equipment order. By the ...

  • XRF plastics and polymers analysis | Spectroscopy Solutions

    Plastics are ubiquitous in modern life with polyethylene and polypropylene being two of the most commonly used. These plastics can be found in anything from plastic carrier bags to children’s toys, to thermoplastics and consumer products. Polyethylene and polypropylene are polymers produced from α-olefins which are polymerized using the high-pressure Ziegler–Natta process. The ...

  • Process analytics in vinyl chloride monomer (VCM) plants – Case Study

    Vinyl chloride monomer (VCM), made from ethylene and chlorine by pyrolysis, is the feedstock for the production of the very common plastic material PVC. Modern VCM plants use integrated processes, combining endothermic and exothermic reactions in an almost energy balanced operation. Plants optimize the product quality, plant safety and cost efficiency by using advanced process control equipment ...

  • Painting an ever-greener picture in car production

    The announcement earlier this year that BMW Group is investing a further £100 million to increase production at its Oxford plant is good news for those buyers who have been waiting around three months to get their hands on the steering wheel of the legendary new MINI. In the paint shop, this poses a special challenge – how do you reconcile the demands of more throughput, less maintenance downtime ...

  • The search for sustainable plastics

    As petroleum-based polymers foul our oceans and litter our lives, researchers seek more environmentally friendly ways to meet demand for durable, versatile materials. The fate of the world’s oceans may rest inside a stainless steel tank not quite the size of a small beer keg. Inside, genetically modified bacteria turn corn syrup into a churning mass of polymers that can be ...
