CTS Internal Floating Roofs for storage tanks

Typically atmospheric storage tanks have contributed significantly to emissions of volatile organic hydrocarbons (VOC’s). When our society developed an understanding of the economic aspects and environmental impact being the result of these emissions several products were developed to reduce emissions. At the basis and forefront of these developments was the internal floating roof. By covering major part of the liquid surface and through an effective seal the emission reduction by installing an internal floating roof is in excess of 90%. Also the API committee has acknowledged the importance and relevance of this development by maintaining a standard for internal floating roofs (API 650 Appendix H). Floating roofs are available in a wide range of materials including aluminium and stainless steel and as vapour containing as well as direct contact roofs..
