Energy Targets & Benchmarks – What are they and how can they be useful?
Energy targets and benchmarks are useful metrics to assist in the identification of energy reduction potential and opportunities. Bench-marking is the process used to quantifying the current energy use of a plant an comparing that use to some other established quantity. The comparison could be to historical plant performance, other similar plants, industry averages, best in class (i.e. best in the industry), or best practice / best available technology. Once a benchmark has been established a gap analysis – an identification of the reasons the current usage differs from the benchmark, can be conducted. This webinar discussed the different types of benchmarks and how they can be determined, how benchmarks can be used to identify opportunities and a brief introduction to gap analysis.

Control Optimisation - Fan System Tuning
Fan system efficiency is dependent on much more than just the efficiency of the fan itself. Following on from previous webinars we will explore the importance of fan system control, including the use of multiple fans in series and parallel and how significant gains can be made from correctly tuning the system.
Using several industrial case studies this webinar explores the additional spill over benefits of a well-tuned fan system in terms of process yield, product quality, maintenance and reliability improvements as well as energy efficiency savings. The material will also be applicable to large HVAC systems as well as general process engineering related applications.

Reducing Process Heat Use - Performance Targets
Minimising thermal energy use through improved energy efficiency is a critical method for increasing plant profitability and long-term sustainability. Going beyond housekeeping measures and simple waste energy recovery projects can be difficult to know where to start.
This webinar presents a systematic method, Pinch Analysis, for determining process heat performance targets. These targets are useful for identifying which unit operations and processes are the most inefficient and are therefore the first place to investigate further. Industrial examples of the application of Pinch Analysis are presented to demonstrate the method.

Understanding Water Hammer in Steam and Condensate Systems
Much of the process heating requirements of industry are supplied via steam systems, with substantial efficiency gains to be made in most installations. One of the single biggest challenges facing operators of steam systems is dealing with water hammer and the danger it can pose to piping, equipment and people.
This webinar provides an overview of the four different types of water hammer and how it is caused and can this be prevented. Applications to both steam and condensate systems are covered.

Fan System Duct Design - System Troubleshooting
Fan system efficiency is dependent on much more than just the efficiency of the fan itself. The design and configuration of ducting can determine a significant portion of the load on the fan(s) in terms of static pressure (head) requirements, with much of this load being unnecessary with correct attention to detail at the design phase. Poor duct design can also compromise the performance of individual unit operations, such as heaters/coolers, cyclones and bag houses as well as directly impacting on process efficiency, quality and yields.
Using several industrial case studies this webinar explores the secrets to good process air duct design with the view to apply these learnings to both new and existing installations. The material will also be relevant to those that operate large HVAC systems will substantial airflows passing through heat exchangers and filter banks.
Webinar - Fan System Duct Design - System Troubleshooting - 24th August 2016
Flow control of Pump Systems
There are numerous flow control methods available for pump systems and the overall efficiency and energy use of the system can be dramatically affected by the method employed. Each method has its place but selecting the appropriate method requires consideration of the system requirements (flow and pressure) and any variability. Much of the inefficiencies in pump systems arise from using suboptimal flow control methods and the related issue of pump oversizing. This webinar reviews common flow control strategies and discuss the relative merits and applications of these strategies.

In depth Cast Studies - Sizing Compressed Air Systems
When considering the supply side of a compressed air system, one of the biggest sources of efficiency losses is the incorrect sizing of the compressors themselves. This applies to both single and multiple compressor installations. Using in-depth case studies this webinar addresses how to correctly size compressed air system equipment, both large and small, for both existing and green field applications. The opportunities associated with replacing existing equipment will also be addressed.

Compressed Air System Demand: Needs v Actual Usage
The single biggest saving in most industrial compressed air systems is demand side (point of use) savings from leaks, artificial demand, inappropriate use and peak load management. Identifying these opportunities is easy; however navigating how to make a meaningful change in demand can be difficult. This webinar will explore several ways to differentiate between how much compressed air you need against what is actually being used. Several case studies will be used to demonstrate how to identify and quantify these opportunities so that the opportunities can be justified and implemented.

Pump Curves and Pump Sizing
It is estimated that as many as 75% of industrial pumps are oversized and as a result pump systems are operated at far from optimal conditions. Much of the problem is caused due to incorrectly sizing of the pump during pump selection. Oversizing pumps leads to significant increases in initial capital expenditure, energy and maintenance costs. This webinar will address the reasons why so many pumps are oversized and the impact this has on total life cycle costs. Industry case studies will be used to illustrate the increase cost associated with oversizing pumps and ways to avoid common mistakes in pump sizing and how to address existing oversized pump systems. The webinar will be of interest to energy managers, operational and maintenance personal, technical staff, and engineers.
Sponsored by the EECA Business programme, this webinar is presented by Dr Martin Atkins, a Senior Chemical Engineer from the University of Waikato Energy Research Centre.

Industrial Boiler Water Treatment and chemistry - An Introduction
Controlling corrosion and deposition within any industrial boiler is critical to ensuring safe, reliable and efficient operation, but is often shrouded in mystery. For most industrial boilers this task is carried out with the use of expensive and proprietary chemical treatments, but not always well executed. The basis of effective industrial boiler water chemistry control is normally well understood, but when carried out incorrectly leads to avoidable increases in operating costs, plant pressure equipment failures & forced outages and potential contamination of downstream equipment.
This webinar will introduce the fundamentals of industrial boiler water treatment; including makeup water treatment, corrosion control, deposition control, blow down control, and carryover control. The webinar will be of interest to energy managers, operational and maintenance personal, technical staff, and engineers.

Off Design Pump Systems
Fan systems are large energy users at many industrial and commercial sites, with numerous opportunities to make significant energy saving improvements, often through relatively minor and inexpensive system modifications or control set point adjustments. With most fans integrated into complex systems it is critical to understand the system as a whole to ensure an optimal outcome, beyond just the basic energy savings.
This webinar will outline the fundamental principles of establishing your system curve, and how fan selection and fan control strategies can impact on the stability and efficiency of the system as a whole. Several industrial case studies will be used to demonstrate the use of systems curve analysis to make gains in system capacity (de-bottlenecking), reliability and energy efficiency. It will be of interest to energy managers, operational and maintenance personal, technical staff, and engineers.
