Fractionation tray having a manway unit

A method of retrofitting a fractionation tray having an existing manway unit with a new manway unit, the method comprising the steps of:

• (i) providing a fractionation tray having the existing manway unit positioned to cover a manyway opening of the fractionation tray, wherein:
• the manway opening is framed by one or more fractionation tray panels having apertures through the panel(s) from one major surface to another major surface adjacent to the manway opening, and
• the exiting manway unit is secured to the fractionation tray by one or more bolting assemblies disposed through the apertures;
• (ii) removing, sliding away, or turning away the one or more bolting assemblies and removing the existing manway unit from the fractionation tray;
• (iii) providing a new manway unit, the new manway unit comprising;
• and
• finger elements extending from the second side edge, wherein the finger elements of the second side edge are configured to be received within the apertures adjacent to a first side of the manway opening,
• wherein the manway unit is configured to open and close by rotation of the finger elements with the apertures, and
• (iv) installing the new manway unit by inserting finger elements of the first manway panel into the apertures of the adjacent fractionation tray panel(s),
• thereby retrofitting a fractionation tray having an existing manway unit with a new manway unit.

• the first manway panel having perforations for the passage of fluid and first and second opposing side edges and two opposing end edges;
• (ii) removing, sliding away, or turning away the one or more bolting assemblies and removing the existing manway unit from the fractionation tray;
• (iii) installing finger elements on one or more sides of the manway panel(s) thereby creating a modified manway unit, wherein the modified manway unit is configured to open and close by rotation of the finger elements within the apertures, and
• (iv) installing the modified manway unit by inserting the finger elements into the apertures of the adjacent fractionation tray panel(s),
• thereby retrofitting a fractionation tray having an existing manway unit.
