  • Electrical Heat Tracing international harmonization now and in the future
    IEEE Industry Applications Magazine, 2002
    Co-Authors: C. Sandberg, N.r. Rafferty, M Kleinehanding, J J Hernandez
    Abstract:

    In the past, Electrical Heat Tracing has been thought of as a minor addition to plant utilities. Today, it is recognized as a critical subsystem to be monitored and controlled. A marriage between process, mechanical, and Electrical engineers must take place to ensure that optimum economic results are produced. The Internet, expert systems, and falling costs of instrumentation will all contribute to more reliable control systems and improved monitoring systems. There is a harmonization between Europe and North America that should facilitate design and installation using common components. The future holds many opportunities to optimize the design.

  • control and monitoring of Electrical Heat Tracing
    Petroleum and Chemical Industry Technical Conference, 2001
    Co-Authors: C. Sandberg, B Holmes, J Beres
    Abstract:

    Electrical Heat Tracing has advanced to the place where it is now considered critical to the operation of most process plants. With its increased importance comes increased need for its control and monitoring. This paper reviews the history of control and monitoring, gives a synopsis of some available methods and techniques, and provides a look at some future extensions of the current technology.

  • standards power distribution monitoring and control of Electrical Heat Tracing a global view
    IEEE Industry Applications Society Annual Meeting, 2000
    Co-Authors: C. Sandberg, B Rafferty, M Kleinehanding, J J Hernandez
    Abstract:

    As Electrical Heat Tracing has become a major and more complicated utility subsystem in production plants, increased focus has been placed on its control, monitoring, and Electrical supply systems. This is especially true when the Tracing is used for process control. Different schemes have evolved in North America compared with Europe. Supply of Electrical power is governed by local codes and practices. The Electrical Heat Tracing, however, is governed by approvals and company practice. The Zone System has been accepted in North America and increased installations using this classification will be seen soon. This paper looks at the different schemes for Electrical power supply, monitoring and control, and the Heat Tracing itself.

  • Panel discussion on Electrical Heat Tracing
    199 IEEE Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.99CH36364), 1999
    Co-Authors: C. Sandberg, Peter Baen, V. Rowe, J. Turner
    Abstract:

    Electrical Heat Tracing has matured in the last 30 years to be the preferred method of both freeze protection and process temperature maintenance. In most applications. The IEEE has provided guidance for the design and installation of Heat Tracing through recommended practices and standards such as those sanctioned by the IEEE Power Engineering Society (PES) and IEEE Industry Applications Society (IAS). Changes in product, design, control and monitoring, and approvals all have impacted the evolution of the engineering topic of Electrical Heat Tracing. In this panel discussion we highlight the available standards and recommended practices with a focus on power generation processes. Hopper Heating, instrument Heating and special applications are also discussed. The IEC standards being modeled by the CEC (Canadian Electrical Code) and NEC (USA National Electrical Code), with acceptance of the Zone classification system give the designer more opportunity to optimize the Heat Tracing system. The NESC (National Electrical Safety Code) also plays a part in the power generation side of the equation. Economic analyses of comparisons of steam Tracing and Electrical Tracing as well as advancements in monitoring and control add another dimension to the situation.

  • secondary factors in Electrical Heat Tracing design
    Petroleum and Chemical Industry Technical Conference, 1996
    Co-Authors: C. Sandberg, N.r. Rafferty, G Kuse, W.e. Mcbride
    Abstract:

    Electrical Heat Tracing has become the preferred method of Heat Tracing in many applications. The standard IEEE 515 Heat transfer equation defines the Heat losses for an infinite pipe with homogeneous insulation. In practical applications pipes freeze at valves, pipe supports, open ended vents and other anomalies. Heat Tracing design must provide design rules for these anomalies and estimate the Heat losses. This paper extends the design criteria for what we call secondary factors. These secondary factors become critical when temperature at these items is not maintained. In the past, vendors have provided a singular Heat loss value for valves, pipe supports and open ended vents that were linearly dependent on pipe diameter. Analysis shows these features of a piping system have Heat losses that are not linear with pipe diameter. Valve Heat loss is a function of the area of the valve and not its pipe diameter. Extensive finite element analysis has been performed on these features, and the results are reported in this paper with estimates of the factors that may be used for estimating Heat loss. These factors are explained for manual calculations and for computer aided design. It has been estimated that up to 30% of total Heat loss is due to valves and supports. Proper engineering, including better thermal insulation, can significantly reduce both installed and operational costs.

  • Ambient proportional control reduces Electrical Heat Tracing costs
    Conference Record of 2000 Annual Pulp and Paper Industry Technical Conference (Cat. No.00CH37111), 2000
    Co-Authors: C. Thomas, P.r. Baen
    Abstract:

    A 1998 Pulp and Paper Industry Committee Conference paper addressed revisions to Article 427 in the National Electrical Code and alternatives to using specialty circuit breakers for electric Heat Tracing (EHT). Further advancements in electronics for Electrical Heat Tracing controls are now providing significant reductions in the costs associated with the design, installation, operation and maintenance of Electrical Heat Tracing systems. This paper addresses some of the technological challenges of configuring the control relays to reduce or eliminate Electrical noise, as well as the specific cost savings associated with every aspect of such systems.

  • why train in the use of Electrical Heat Tracing

  • maintaining Electrical Heat Tracing systems for pulp and paper mills
    Pulp and Paper Industry Conference, 1998
    Co-Authors: P.r. Baen
    Abstract:

    Heat Tracing is most often associated with winterization of piping, tanks and instrumentation. As such, its role in a pulp or paper mill's preventive maintenance program can be easily understood. However, many year-round plant functions, some critical to plant operation, depend on proper Heat Tracing system performance. This paper addresses several aspects of Heat Tracing applications that deserve routine attention to improve the systems' overall performance and maintainability.

  • Training in the use of Electrical Heat Tracing "a course outline"
    Record of Conference Papers. IEEE Industry Applications Society 44th Annual Petroleum and Chemical Industry Conference, 1
    Co-Authors: P.r. Baen, M. Goodman, W.e. Mcbride, J. Rodriguez
    Abstract:

    Although many aspects of Electrical Heat Tracing have been the subjects of technical presentations, the important area of training has not. With increasing emphasis on training to improve overall efficiencies and plant safety, the need for this paper is amplified by fading field expertise caused by staff reductions and retirements. In today's petrochemical, refining and processing plants, Electrical Heat Tracing is commonly found in hazardous (classified) locations. Because it is attached to in-line valves, pumps and other equipment that is regularly maintained, it can be exposed to greater physical abuse than other pieces of Electrical equipment. This paper is intended to be a basic primer for establishing a training program to identify the concepts and considerations necessary to ensure safe and effective electric Heat Tracing systems.

  • Electrical Heat Tracing for surface Heating on arctic vessels and structures to prevent snow and ice accumulation
    Petroleum and Chemical Industry Technical Conference, 2012
    Co-Authors: H Brazil, B Conachey, G Savage, Peter Baen
    Abstract:

    The Proposed “IEEE 45.8 Recommended Practice for Electrical Installations on Shipboard - Cable Systems” will reference EHT (Electrical Heat Trace) for Heating pipes, tanks, and instrumentation on-board ocean-going vessels. The globally recognized IEEE 515 Standard for resistance Heat Tracing addresses “traditional” freeze protection and temperature maintenance applications on-board tankers and FPSO (Floating Production, Storage, and Offloading) facilities, but not for keeping un-insulated surfaces above freezing. As fossil fuels are discovered offshore in arctic regions, their development requires increasing resources to prevent the accumulation (or melting) of snow and ice. Outdoor stairs, handrails, walkways, and other exposed and un-insulated surfaces require protection in these harsh environments. These represent growing requirements for EHT to be installed on, in or under surfaces to reduce unsafe conditions during normal operations or during emergency conditions.

  • Beyond Electrical Heat Tracing: safety showers update
    Record of Conference Papers. Industry Applications Society. Forty-Ninth Annual Conference. 2002 Petroleum and Chemical Industry Technical Conference, 2002
    Co-Authors: Daleep Mohla, N.r. Rafferty, F. Tomas, Peter Baen
    Abstract:

    Since their introduction to industry, safety showers and eyewash stations have required winterization to ensure operation during subfreezing ambient conditions. However, a move to provide tempered water for chemical burn victims will have significant implications for present Electrical Heat Tracing practices on safety shower applications.

  • Safety considerations for Electrical Heat Tracing
    IEEE Industry Applications Magazine, 1996
    Co-Authors: Peter Baen, Daleep Mohla, N.r. Rafferty, R. Jones, L. Robicheaux, C. Sandberg
    Abstract:

    Since the advent of Electrical Heat Tracing over 50 years ago, many challenges have confronted industry to ensure safe and reliable Heat Tracing operation. Reliability of Heat Tracing systems can directly affect safety-related operations, such as fire protection and emergency eyewash and safety showers. As a good practice, the safety of process systems should not be dependent on the performance of a single component of the Heat Tracing system. The primary purpose of this article is to address the issue of high-impedance, low-current faults that have been reported in Electrical Heating cables. These faults usually initiate from phase to ground but have currents that are insufficient to trip the circuit protective device. However, the faults can dissipate enough energy to cause fires and other equipment damage.
