Oil and gas separators can have three general configurations: vertical, horizontal, and spherical.Vertical separators can vary in size from 10 or 12 inches in diameter and 4 to 5 feet seam to seam (S to S) up to 10 or 12 feet in diameter and 15 to 25 feet S to S. Horizontal separators may vary in size from 10 or 12 inches in diameter and 4 to 5 feet S to S up to 15 to 16 feet in diameter and ...
Usually, each floor drain is connected to a trap, to prevent sewer gases from escaping into indoors spaces. A floor sink is a type of floor drain primarily used as an indirect waste receptor. It is generally deeper than a standard floor drain and can have a full or partial grate, or no grate as required to accommodate the indirect waste pipes.
A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces.
