They play an important role in supporting various processes, including ethylene production, separation, and reaction processes. <\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n        <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/07\/nozzle-ind-cool-006-image_011.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n    <\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Air compressors draw in atmospheric air, compress it to high pressure, and supply it to each process. However, during summer, <span style=\"font-weight:bold\">rising ambient temperatures<\/span> cause the air to expand and its density to decrease, reducing the mass of air that can be drawn in and consequently <span style=\"font-weight:bold\">lowering the supply of compressed air<\/span>.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">As a result, the reduced intake air mass can lead to a <span style=\"font-weight:bold\">shortage of compressed air<\/span> required by each process. This may lower equipment performance, limit processing capacity, and affect the stable operation of the entire plant. <\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Looking for a solution to this issue, a facility manager at the petrochemical plant consulted IKEUCHI, which has extensive experience in gas turbine inlet air cooling.<\/p>\n<div style=\"text-align: center;margin: 50px 0\">\n        <a href=\"https:\/\/www.dry-fog.com\/en\/contact\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"background-color: #e67f00;color: #ffffff;font-size: 15px;font-weight: bold;text-decoration: none;padding: 15px 30px;border-radius: 5px\">Contact Us<\/a>\n    <\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Solutions Proposed by IKEUCHI<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Drawing on its technical expertise and proven experience in gas turbine inlet air cooling, IKEUCHI proposed a <span style=\"font-weight:bold\">compact inlet air cooling system<\/span> sized for the plant\u2019s existing air compressors.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n       <a href=\"https:\/\/www.dry-fog.com\/en\/projects-technology\/technical-report\/sol-coo-gtiacs\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/07\/nozzle-ind-cool-006-image_021.jpg\" alt=\"Side View of the Mist Spray Layout\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/a><figcaption style=\"margin: 1rem auto 3rem;text-align: center;font-size: 0.85rem;color: #666\">Gas turbine inlet air cooling system (from an actual installation)<\/figcaption><\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Our specialized spray nozzles generate <a href=\"https:\/\/www.dry-fog.com\/en\/projects-technology\/technical-report\/basics-012\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight:bold\">Semi-Dry Fog<\/span><\/a>, a fine spray with a mean droplet diameter of 10 to 30 \u03bcm.
