It is also very useful when there are restrictions on visible flames due to operational, environmental, town planning or installation constraints. <\/p>\n<p class=\"p2\">Unlike a flare, the vent stack is not designed to burn the gas, but rather to discharge it at a height and under conditions that facilitate its dilution in the atmosphere. That is why it is used when the primary safety criterion is flameless venting with safe dispersion, rather than controlled combustion. <\/p>\n<p>&nbsp;<\/p>\n<h3 class=\"p1\">OPERATION AND DESIGN CRITERIA<\/h3>\n<p class=\"p2\">A good design must take into account the discharge scenarios, the gas flow rate and conditions, the need for safe dispersion, and the potential for radiation in the event of accidental ignition. Added to this are the distances to adjacent equipment, the surrounding environment and compatibility with the rest of the plant\u2019s relief or flare system. <\/p>\n<p>&nbsp;<\/p>\n<h3 class=\"p1\">PREMATECNICA DESIGNS AND IMPLEMENTS YOUR COLD VENT<\/h3>\n<p class=\"p2\">Each cold vent requires a specific design basis. At PREMATECNICA, we analyse the process conditions, the venting scenario, the gas characteristics, the discharge height, the dispersion criteria, the risk of accidental ignition, and the installation and operational restrictions. <\/p>\n<p class=\"p2\">Building on this foundation, we help to define the most suitable configuration and integrate the vent stack with the rest of the plant, including piping, utilities, support structures, insulation where applicable, as well as supervision of assembly, commissioning, maintenance and inspections. Where the project requires it, we carry out dispersion and radiation studies, as well as CFD support, to validate the solution and facilitate its safe integration into the plant. <\/p>\n<p><a href=\"https:\/\/prematecnica.com\/wp-content\/uploads\/2026\/06\/Dispersion_ANSYS_CFD.png\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-4159 size-full\" src=\"https:\/\/prematecnica.com\/wp-content\/uploads\/2026\/06\/Dispersion_ANSYS_CFD.png\" alt=\"\" width=\"440\" height=\"234\" srcset=\"https:\/\/www.prematecnica.com\/wp-content\/uploads\/2026\/06\/Dispersion_ANSYS_CFD.png 440w, https:\/\/www.prematecnica.com\/wp-content\/uploads\/2026\/06\/Dispersion_ANSYS_CFD-300x160.png 300w\" sizes=\"(max-width: 440px) 100vw, 440px\" \/><\/a><\/p>\n","protected":false},"featured_media":5133,"parent":0,"template":"","meta":{"_acf_changed":false},"categoria-producto":[42,43],"representada":[],"sector":[122,87,123,121],"class_list":["post-5155","producto","type-producto","status-publish","has-post-thumbnail","hentry","categoria-producto-combustion","categoria-producto-industrial-flares","sector-chemical-petrochemical-industry","sector-energy-and-fuels","sector-process-industry","sector-renewable-gases"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/producto\/5155","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/producto"}],"about":[{"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/types\/producto"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/media\/5133"}],"wp:attachment":[{"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/media?parent=5155"}],"wp:term":[{"taxonomy":"categoria-producto","embeddable":true,"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/categoria-producto?post=5155"},{"taxonomy":"representada","embeddable":true,"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/representada?post=5155"},{"taxonomy":"sector","embeddable":true,"href":"https:\/\/www.prematecnica.com\/en\/wp-json\/wp\/v2\/sector?post=5155"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
