The low boiling temperature also comes with a low flashpoint. In combination with oxygen, these components can most likely form an ignitable mixture and therefore, they pose the highest risk for explosion and fire.<\/p>\n\n\n\n<p>The behaviour of light ends is like <strong>benzine<\/strong> and poses a safety risk in thermal oil systems.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><a href=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-1030x234.jpg\" alt=\"\" class=\"wp-image-9879\" width=\"531\" height=\"121\" srcset=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-1030x234.jpg 1030w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-300x68.jpg 300w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-768x175.jpg 768w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-1536x349.jpg 1536w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-2048x465.jpg 2048w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-1500x341.jpg 1500w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-705x160.jpg 705w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-dodekan-450x102.jpg 450w\" sizes=\"auto, (max-width: 531px) 100vw, 531px\" \/><\/a><figcaption>Example dodecane chain<br \/>(average mass fraction in light-ends, flashpoint 71 \u00b0C)<\/figcaption><\/figure>\n<br \/><a class=\"qe-faq-top\" href=\"#qe-faqs-index\"><i class=\"fa fa-angle-up\"><\/i> Back to Index<\/a>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div id=\"qaef-11193\" class=\"qe-faq-list light-ends-and-flashpoint-management\">\n\t\t\t<div class=\"qe-list-title\">\n\t\t\t\t<h4>\n\t\t\t\t\t<i class=\"fa fa-question-circle\"><\/i> How are light-ends generated and what happens in the heat transfer oil system?\t\t\t\t<\/h4>\n\t\t\t<\/div>\n\t\t\t<div class=\"qe-list-content\">\n\t\t\t\t\n<p> <\/p>\n\n\n\n<p>Due to the high temperatures, hydrocarbons in thermal oil decompose to form hydrocarbon with shorter chains \u2013 the light-ends. This process continuously takes place in each system during operation; the quantity of the decomposition product however depends on temperature and the type of oil used. <br>Generally, the following items apply:<strong> The higher the operating temperature is, the higher is the generated quantity of light-ends<\/strong>. If the fraction of light-ends increases, the flashpoint of the heat transfer oil will be lower.<\/p>\n\n\n\n<p>This process is completely normal. If, however, no flashpoint management has been implemented, problems will begin. Over time, the decreasing temperature of the flashpoint possibly endangers the operating safety. That means, light ends evaporate already at low temperatures and can become <strong>slightly flammable<\/strong>.<\/p>\n\n\n\n<p>Furthermore, the increase of light ends supports cavitation on mechanical components of the systems, e.g. in pumps. Therefore, it is recommended to operate an <strong>active flashpoint management<\/strong> to keep the flashpoint on a continuously high and safe level.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><a href=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-1030x328.jpg\" alt=\"\" class=\"wp-image-9876\" width=\"511\" height=\"163\" srcset=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-1030x328.jpg 1030w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-300x95.jpg 300w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-768x244.jpg 768w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-1536x489.jpg 1536w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-2048x652.jpg 2048w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-1500x477.jpg 1500w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-705x224.jpg 705w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/slider-kavitation-450x143.jpg 450w\" sizes=\"auto, (max-width: 511px) 100vw, 511px\" \/><\/a><figcaption>Cavitation damages on pump impellers<br \/>(source: Allweiler)<\/figcaption><\/figure>\n<br \/><a class=\"qe-faq-top\" href=\"#qe-faqs-index\"><i class=\"fa fa-angle-up\"><\/i> Back to Index<\/a>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div id=\"qaef-11194\" class=\"qe-faq-list light-ends-and-flashpoint-management\">\n\t\t\t<div class=\"qe-list-title\">\n\t\t\t\t<h4>\n\t\t\t\t\t<i class=\"fa fa-question-circle\"><\/i> How do I determine the exact flashpoint of my oil?\t\t\t\t<\/h4>\n\t\t\t<\/div>\n\t\t\t<div class=\"qe-list-content\">\n\t\t\t\t\n<p>It is important to know that <strong>light-ends are volatile<\/strong> and therefore, taking an open, hot sample of heat transfer oil provides a wrong result.

In this case, part of the oil is replaced by fresh oil, whereby a certain percentage of the generated light ends will be discharged out of the system. With this, the flashpoint will increase to a higher level for a short time. However, this solution does not replace a flashpoint management and is only a short-term solution, mostly in case of an <strong>emergency<\/strong>. In addition, in some circumstances, the oil change is associated with a standstill of the system and \u2013 depending on the oil used \u2013 it causes high running costs.<\/p>\n\n\n\n<p>A <strong>widely used approach<\/strong> approach for driving the light-ends out of the thermal oil is the so-called <strong>boiling out of the system<\/strong>. Even in connection with the already mentioned problem of cavitation, the heat transfer oil systems are boiled out already before the initial commissioning to drive out possibly existing water. Later, this is also done during the running operation to drive out light-ends possibly occurred. With this, it is avoided that light-ends get into the pump housing as a gas bubble and cause damages. Mostly, this process of boiling out is simply repeated in regular intervals; however, this comes again with longer standstills.<\/p>\n\n\n\n<p>Otherwise, in addition to the methods introduced above, light ends can also be driven out of the system by means of <strong>distillation<\/strong>. Correctly intergraded, this solution has the advantage that it can be carried out during the running operation of the system. In this procedure the light ends are solved out of the heat transfer oil and separated. With this, the above-mentioned <strong>active flashpoint management can be implemented<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized is-style-default\"><a href=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-1030x772.jpg\" alt=\"\" class=\"wp-image-11342\" width=\"518\" height=\"389\" srcset=\"https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-1030x772.jpg 1030w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-300x225.jpg 300w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-768x576.jpg 768w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-1536x1152.jpg 1536w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-1500x1125.jpg 1500w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-705x529.jpg 705w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-450x337.jpg 450w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq-1320x990.jpg 1320w, https:\/\/ness.de\/wp-content\/uploads\/2020\/02\/Flashpoint-WebFaq.jpg 1586w\" sizes=\"auto, (max-width: 518px) 100vw, 518px\" \/><\/a><figcaption>Example for a flashpoint development without flashpoint management<\/figcaption><\/figure>\n<br \/><a class=\"qe-faq-top\" href=\"#qe-faqs-index\"><i class=\"fa fa-angle-up\"><\/i> Back to Index<\/a>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div id=\"qaef-11196\" class=\"qe-faq-list light-ends-and-flashpoint-management\">\n\t\t\t<div class=\"qe-list-title\">\n\t\t\t\t<h4>\n\t\t\t\t\t<i class=\"fa fa-question-circle\"><\/i> An active flashpoint management as preventive action against light-ends?\t\t\t\t<\/h4>\n\t\t\t<\/div>\n\t\t\t<div class=\"qe-list-content\">\n\t\t\t\t\n<p>Exactly!
