Heat Recovery In a Chemical Processing Plant

Posted by Paul Mueller Academy Staff on Apr 24, 2017 1:39:04 PM

 

You have the difficult task of identifying processes in your facility where you can “go green”. There are hidden opportunities throughout your plant to be more sustainable and efficient, but you need someone who’s an expert on the subject to pinpoint them and provide solutions. If your company is implementing or has implemented a comprehensive sustainability policy, heat recovery may be a way to reach your goals. Here is one example to get you thinking about your specific opportunities.

With multiple dimple sheets that need to be tacked and fit to the same tank head it can be difficult to get them to line up properly. Today, Jeremy is going to show you how to fit and trim dimple coil to a tank head.

There are a couple challenges you might face when trimming and fitting dimple sheets to a tank head.

  • Challenge 1: The dimple doesn't lay down flat against the tank head.
  • Challenge 2: It can be difficult to trim the dimple sheets to fit together correctly.

Here's how to overcome these two challenges:

Why Is My Heat Transfer Leaking?

Posted by Joe Mitchell on Nov 1, 2016 4:30:57 PM

 

When heat transfer leaks you can risk contamination in your whole system.  There are typically four main reasons a leak could occur: water hammering, stress corrosion cracking, over pressurizing, and lack of supports.

How a Heat Transfer Consultation Saved a Brewery Money

Posted by Paul Mueller Academy Staff on Oct 3, 2016 3:50:59 PM

 

 Whether you are installing heat transfer in your end product or using it in your direct operations it can be a real energy saver.  However getting the right specifications is crucial and understanding the detailed spec sheet can be daunting.  There are always challenges -  what if you don't get it right?  What if  the resulting product is not what you need?  Sometimes it helps to double check the infinite details affecting flow rates, pressure drops and heat loads.  A quick phone consultation might even help you make beer better.

Overview of Plate Heat Exchanger Technology

Posted by Paul Mueller Academy Staff on Aug 31, 2016 3:27:14 PM

 

Plate heat exchangers are a highly useful industrial component for passively (without extra energy) controlling fluid temperatures using other fluids that may already be part of the industrial process. Here’s a brief explanation of how they work and their benefits, as well as links to more helpful resources.

Which Heat Exchanger Is Best? The Three Main Types Explained...

Posted by Paul Mueller Academy Staff on Aug 31, 2016 2:59:46 PM

 

Heat exchangers all work by passing a hot fluid and a cold fluid across opposite sides of a piece of metal. The heat from one fluid passes across the metal (which is thermally conductive) into the other fluid without the fluids making contact. High fluid velocity, high turbulence, high surface area and a large temperature differential all contribute to more efficient heat transfer. However, different designs are more efficient than others depending on the application.

How to Troubleshoot a Plate Heat Exchanger

Posted by Paul Mueller Academy Staff on Aug 31, 2016 2:43:51 PM

 

This article is dedicated to identifying issues your plate heat exchanger (PHE) might be having, and setting you on the path to the right solution. Nearly all issues boil down to some form of plate fouling or gasket failure, but it’s important to determine whether it’s a one-time problem or an inherent flaw in your system (the PHE is specified incorrectly). The first step is to identify the symptoms of your underperforming heat exchanger.

How to Identify a Differential Leak in a Plate Heat Exchanger

Posted by Paul Mueller Academy Staff on Aug 31, 2016 2:39:13 PM

 

On occasion, a plate heat exchanger (PHE) can fail when a plate develops a small crack or in some rare instances when a gasket is dislodged or damaged. When one of these failures causes the two fluids to mix, it’s called a differential leak. This can be particularly damaging in the food, beverage and chemical industries, and can lead to significant downtime. Fortunately, plate heat exchangers are modular, and once the defective plate or gasket is located, it and an adjacent plate simply need to be removed and the PHE can go back into service, operating at a slightly decreased capacity until you acquire the replacements. So how do you find the defective plate? We’ve outlined four simple steps below.

Good Maintenance Habits for Plate Heat Exchangers

Posted by Paul Mueller Academy Staff on Aug 31, 2016 2:38:07 PM

 

Just like a car or a computer, a heat exchanger needs regular maintenance to keep running at peak performance. Fortunately, PHE’s are generally easier to maintain than other types of heat exchangers, and problems tend to be easier to diagnose.
