Title (EN) COATING METHOD WITH EMISSIONS ABATEMENT I
(FR) PROCEDE DE REVETEMENT AVEC DIMINUTION DES DEGAGEMENTS
Abstract: front page image
(EN)A process of coating a workpiece using a sprayable coating composition in a spraybooth that communicates with a water wash, said water wash permitting contact between airborne components of said sprayable coating composition that enter said water wash and scrubbing water of a high volume, low energy wet scrubber operating at an inlet and outlet pressure difference in a range of less than about 10 inches of water, the improvement which comprises (A) spraying in said spraybooth a scrubbable coating composition comprising a volatile organic compound that boils above about 98 C at atmospheric pressure and is soluble in water above about 6% by weight at 20 C; (B) capturing in said scrubbing water a volatile portion of said scrubbable coating composition wherein said volatile portion comprises an amount of said volatile compound; and (C) maintaining the concentration of said volatile organic compound in said scrubbing water below that concentration at which capturing efficiency falls below 10% of a maximum efficiency.
(FR)Procede de revetement d"une piece utilisant une composition de revetement pulverisable dans un compartiment de pulverisation qui communique avec un laveur a eau, ce laveur a eau permettant le contact entre les composants entraines par l"air de ladite composition de revetement pulverisable qui rentre dans le nettoyeur a eau et l"eau de lavage d"un epurateur humide a basse energie et volume eleve fonctionnant sous une difference de pression entre l"entree et la sortie dans une zone de moins d"environ 10 pouces d"eau; amelioration qui comprend (A) la pulverisation dans ledit compartiment de pulverisation d"une composition de revetement renfermant un compose organique volatile qui bout au-dessus d"environ 98 C a la pression atmospherique et qui est soluble dans l"eau au-dessus d"environ 6% en poids a 20 C; (B) le captage dans cette eau de lavage d"une partie volatile de ladite composition de revetement lavable ladite partie volatile comprenant une quantite dudit compose volatile; et (C) le maintient de la concentration dudit compose organique volatile dans ladite eau de lavage en-dessous de la concentration a laquelle l"efficacite de captage tombe en-dessous de 10% d"une efficacite maximale.
