Application<\/strong>
\nThis was an especially critical application due to the corrosiveness of the material to be treated, which was hydrofluoric acid at concentrations of up to 75%.
\nThe new equipment, manufactured from engineering plastics, replaced old equipment of A\u00baC\u00ba lined with PVDF. <\/p>\n

Characteristics<\/strong>
\n\"\"<\/a>Two units were manufactured in consecutive years to replace the old absorbers. The equipment had an internal diameter of 1650 mm, Klopper bottoms, and a useable capacity of 4 m3. <\/p>\n

Each unit came equipped with internal accessories for the feed and distribution of the acid.<\/p>\n

Operating Conditions<\/strong>
\nThe operating conditions of the absorbers were a maximum pressure of 3.5 bar, and a maximum temparature of 70\u00baC.
\nThe absorbers receive hydrofluoric acid in concentrations that reach 75% inside the equipment.<\/p>\n

Material<\/strong>
\n\"\"<\/a>The absorbers were of dual composition, using PVDF as a liner and a carbon fibre entrefase to protect the fibreglass from permeation of the acid through the PVDF. The structural reinforcement was of a novolac vinylester resin DERAKANE470\/300 based FRP. The internal components were manufactured in PVDF. <\/p>\n
