Abstract

a invenção se refere a uma coluna (1) para o tratamento térmico de misturas fluidas, compreendendo um corpo de coluna alinhado de maneira vertical cilíndrico (2) que forma uma cavidade de coluna (3) e uma superfície interna vertical (16), uma pluralidade de bandejas (8) que são montadas na dita cavidade de coluna (3) e espaçadas verticalmente entre si, pelo menos um estrangulamento (11) arranjado dentro do corpo de coluna (2) e se estendendo para longe do dito corpo de coluna (2), e um orifício de inspeção que pode ser fechado (9) formado no estrangulamento (11). a coluna reivindicada é distinguida pelo fato de que, em uma seção transversal vertical da coluna (1), a superfície (15) do revestimento de interseção inferior do estrangulamento (11) direcionada para a cavidade de coluna (3) ou uma tangente com a superfície (15) do dito revestimento de interseção inferior do estrangulamento (11), forma, junto com a superfície interna vertical (16) do corpo de coluna (2) que se estende para baixo a partir do dito estrangulamento (11), um ângulo na faixa a partir de 210° até 267°, pelo menos em algumas seções.
