    PREVENTATIVE MAINTENACE TIPS RYDLYME Descaler | Shell and Tube Heat Exchanger Descaling Scale accumulation in shell and tube heat exchangers can rob the equipment’s efficiency. This scale build up can be made of rust, mineral deposits, calcium, limescale and many other corrosive deposits. Much like changing oil in your car, it is crucial that a preventative maintenance program be put in place on your equipment. The most effective method is to utilize RYDLYME descaling chemical and one of Apex Engineering Product’s Descaling Systems. Even 1/32’’ of scale can cost thousands in unnecessary expenses to keep the equipment running! More importantly - neglecting this scale build up of the heat exchanger can greatly reduce the lifespan of the equipment. Some scale is actually corrosive to the tube material, eating away at the tube walls! Removing this scale in a timely manner will ultimately increase the equipment’s lifespan and efficiency. Before RYDLYME cleaning After RYDLYME cleaning Shell and Tube Heat Exchanger Cleaning Methods Just like in any industry, there is the hard way and the smart way of getting the job done. Traditional methods of tube cleaning such as rodding and hydroblasting are expensive, time consuming and often lead to equipment downtime. In some cases, it’s difficult to access the tubes to hydroblast or rod! This compounds with production loss as well as revenue loss. So, now that we’ve talked about the hard way to clean, let’s talk about the smart way to clean. Using RYDLYME Biodegradable Descaler to remove unwanted scale is easy, safe and quick! The World’s Leading Biodegradable Descaler, RYDLYME, is non-corrosive, non-hazardous and can be disposed of easily! Descaling heat exchangers is made even easier with the use of one of our descaling systems!

  • Mechanical Tube Cleaning: the Emerging Trend in Maintaining Heat Exchanger Efficiency
    2015 WJTA-IMCA Conference and Expo November 2-4 • New Orleans, Louisiana Paper Mechanical Tube Cleaning: The Emerging Trend in Maintaining Heat Exchanger Efficiency Christopher K. Van Name Conco Services Corporation Verona, Pennsylvania, U.S.A. Jason R. Wilburn Conco Services Corporation Verona, Pennsylvania, U.S.A. ABSTRACT Industry today places a high importance on safeguarding the health and wellbeing of both its employees and the environment. Managers in chemical plants and refineries have been tasked to find better, safer ways to clean their heat exchangers while minimizing the impact of wastewater. An emerging trend in maintaining the cleanliness of heat exchangers has been the use of mechanical tube cleaners. These mechanical systems utilize a variety of shooting, brushing and drilling methods combined with low-pressure water (under 700 PSI) to safely and quickly remove even the most tenacious deposits, restoring heat transfer efficiency. As an alternative to current practices, these mechanical tube cleaning systems offer a much smaller footprint than traditional high-pressure water methods, and allow the equipment to be placed much closer to the heat exchanger further reducing congestion during the overhaul. By utilizing lower water pressure, these mechanical tube cleaning systems are much safer to use and generate far less wastewater than high-pressure water methods. The mechanical cleaning technology has proven to be safe, effective and environmentally sound. This paper will address five case studies where positive results were achieved with this emerging technology. Organized and Sponsored by WJTA®-IMCA® SECTION 1 – INTRODUCTION No matter what the type of heat exchangers nor which industries they are being employed in, eventually all of these units will foul.

  • Utilization of Various Projectiles to Mitigate Fouling in Tubular Heat Exchangers
    UTILIZATION OF VARIOUS PROJECTILES TO MITIGATE FOULING IN TUBULAR HEAT EXCHANGERS A dissertation accepted by the Faculty of Energy-, Process- and Bio-Engineering of the University of Stuttgart in Partial Fulfillment of the Requirements for the Degree of Doctor of Engineering Sciences (Dr.-Ing.) by Mohammad Reza Jalalirad, B.Sc., M.Sc. born in Arak, Iran Institute for Thermodynamics and Thermal Engineering University of Stuttgart, Germany Published 2016 Supervisor: Prof. Dr. Dr.-Ing. habil. H. Müller-Steinhagen Co-Examiners: Prof. Dr. –Ing. Günter Scheffknecht and Prof. Dr. –Ing. Stephan Scholl Date of Oral Examination: 21st December, 2015 i ABSTRACT ABSTRACT Heat exchangers are the workhorse of most chemical, petrochemical, food processing and power generating processes. Of the many types of heat exchangers, approximately 60% of the market is still dominated by shell and tube heat exchangers. One major problem of heat exchangers and particularly the shell and tube type is directly related to the deposition of unwanted materials on the heat transfer surfaces. Fouling may cause one or more of several major operating problems: i) reduction of heat transfer, ii) under-deposit corrosion, iii) increased pressure loss and iv) flow mal-distribution. There are many different mitigation techniques available in the market to maintain the surface of heat exchangers clean to some extent. Among them are projectiles of various shapes, materials and hardnesses which circulate via a separate loop through the exchanger. The advantages of this method include effective fouling mitigation and stable operating conditions. Having said that, there are nevertheless numerous unanswered questions such as optimum injection interval, minimum required shear force to remove fouling layers, applicability of projectiles at elevated temperatures, minimum required velocity of projectile propulsion, and the criterion for the selection of projectiles for any specific fouling process.

Traditional tube ID cleaning methods include the use of high pressure water and or chemicals. However, this can not only be dangerous, it also does not completely remove the majority of the deposit from the unit. As a result, Conco has developed and facilitated a mechanical cleaning method that can completely remove the deposit from the unit that is safe, efficient and cost effective. The following storyboard will illustrate this method. I. Equipment Pump System – The Conco ProSeries™ 200B Tube Cleaning System is required to propel the U-Tube cleaning tools through the tubes with adequate water volume and pressure. The unit is available in a 440 Volts, 60 HZ AC, three phase configuration or as a 220 Volt or 380 Volt 50 HZ AC, three phase system. All units have a minimum water requirement of 40 PSI at 36 GPM.

  • Improving Chiller Efficiency Through Automatic Tube Cleaning System Technology
    WP-101 Rev. 0 IMPROVING CHILLER EFFICIENCY THROUGH AUTOMATIC TUBE CLEANING SYSTEM TECHNOLOGY ABSTRACT In this paper, solutions for improving chiller energy efficiency by reducing fouling of shell and tube heat exchangers are discussed. Sponge-ball type automatic tube cleaning system technology is introduced and discussed as a solution for improving chiller energy efficiency and tube cleaning system operating principles are presented. Multiple case studies are provided demonstrating the positive impacts of tube cleaning system technology implementation. INTRODUCTION Shell and tube condensers and heat exchangers are core to a wide range of processes including power generation, oil refining, industrial processing, and HVAC comfort cooling. Unfortunately, this means that “fouling” of these heat exchangers (the accumulation of efficiency-killing deposits) is also pervasive—at extremely high economic and social costs. The expenses associated with fouled heat exchangers and condensers are significant, and include increased power consumption, increased fossil fuel consumption, reduced production, and frequent condenser cleaning costs. Heat exchanger fouling costs have been estimated at 0.25% of the gross domestic product (GDP) of highly industrialized countries in several studies, which, based on estimated U.S. GDP of $15 trillion, translates to fouling-related costs of $37 billion a year. 1 In HVAC applications, fouling of the chiller condenser tubes has substantial impact on the power consumption of the compressor. Even with good water treatment programs, it’s not uncommon to find chillers that appear to be in good working order operating at a fouling factor of 0.0025 hr-ft2-F/Btu or higher — causing compressor power consumption to increase by 25% or more.2 Fouling occurs because cooling water contains minerals, such as calcium and magnesium that precipitate to form deposits on heat transfer surfaces.

Dooley David Rettke Structural Integrity Associates NV Energy Southport, Merseyside, UK Las Vegas, Nevada, USA Email: [email protected] [email protected] 1 Guideline for Finned Tube Cleaning of Air-Cooled Condensers Introduction Steam condensing in air-cooled condensers (ACCs) takes place in specialized heat exchanger tubes designed for optimal heat transfer. Typically, the tubes are composed of carbon steel with exterior (air-side) aluminum coating/cladding, along with external aluminum fins to increase the air-side surface area for heat rejection. Some ACCs, mostly earlier designs, included carbon steel fins on carbon steel heat exchange tubes, with the entire exterior coated with zinc. ACC tubes are normally oval or rectangular in shape and approximately 0.059” (1.50 mm) wall thickness, with closely-spaced fins to facilitate maximum surface area exposure to cooling air flow (Figures 1-3). Air flow is provided by large fans typically positioned below the array of finned tubes, directing air upward in a so-called “forced draft” situation (Figures 4, 5), although an induced-draft design with fans above the array has been introduced that has some potential advantages.

  • Fouling of Heat Transfer Surfaces
    20 Fouling of Heat Transfer Surfaces Mostafa M. Awad Mansoura University, Faculty of Engineering, Mech. Power Eng. Dept., Egypt 1. Introduction Fouling is generally defined as the accumulation and formation of unwanted materials on the surfaces of processing equipment, which can seriously deteriorate the capacity of the surface to transfer heat under the temperature difference conditions for which it was designed. Fouling of heat transfer surfaces is one of the most important problems in heat transfer equipment. Fouling is an extremely complex phenomenon. Fundamentally, fouling may be characterized as a combined, unsteady state, momentum, mass and heat transfer problem with chemical, solubility, corrosion and biological processes may also taking place. It has been described as the major unresolved problem in heat transfer1. According to many [1-3], fouling can occur on any fluid-solid surface and have other adverse effects besides reduction of heat transfer. It has been recognized as a nearly universal problem in design and operation, and it affects the operation of equipment in two ways: Firstly, the fouling layer has a low thermal conductivity. This increases the resistance to heat transfer and reduces the effectiveness of heat exchangers. Secondly, as deposition occurs, the cross sectional area is reduced, which causes an increase in pressure drop across the apparatus. In industry, fouling of heat transfer surfaces has always been a recognized phenomenon, although poorly understood. Fouling of heat transfer surfaces occurs in most chemical and process industries, including oil refineries, pulp and paper manufacturing, polymer and fiber production, desalination, food processing, dairy industries, power generation and energy recovery.
