  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Case study - ABUTEC’s heat recovery unit provides multiple landfill benefits

    ABUTEC Heat Recovery Flare A Pennsylvania-based waste management site needed a solution to burn off harmful gases emitted from decaying waste in their landfill. They also wanted a way to make the most out of the waste that was being burned, so they looked to ABUTEC representatives to devise a plan for combustion. ABUTEC representatives suggested the Heat Recovery Unit to burn off the waste heat ...


  • 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 ...

  • MLM® vs. Conventional RTO Heat Recovery Media

    Random media, in addition to high pressure drop, are also associated with common operational problems when used as the heat recovery media in RTO units. These problems include settling and nesting which leads to even higher pressure drop ...

  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Case study - Increasing primary heat recovery

    OVERVIEW Tekra Corporation is a custom coater of plastic films in Wisconsin, where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early model Regenerative Thermal Oxidizer (RTO). While at the ...

  • Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation

    A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points. These would include explosive compounds present in the vapor stream. The portable TU-51VPVOC (OEM) operates the following process: vapors are recovered from geologic units via SVE, often from a ...

  • Case study - Maximizing heat recovery from your oxidizer and reducing operating costs

    More and more, companies operating air pollution control equipment today realize that the initial capital cost of an oxidizer system can be rapidly eclipsed by continued operating expenses if careful attention is not periodically given to the system. Below are ten tips to ensure your oxidizer is operating at peak performance. The first five tips focus on parameters end-users should know about ...

  • Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study

    During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...

  • Qualifying Combined Heat and Power (CHP) activity

    The EU 2002 draft and 2004 final CHP Directives propose qualifying CHP activity with the quality norm. This norm benchmarks the energy efficiency of CHP plant outputs on external reference power and heat efficiencies. Because the quality norm amalgamates cogeneration and condensing activity its application entails particular perverse effects for high-quality and adapted scale investment in CHP ...
