Abstract
A storage tank includes an oil and water separator in which the frontal area of the coalescers is increased relative to known arrangements of coalescers in oil and water separators. By arranging the coalescers such that the surface area of the coalescers is increased, the efficiency of the coalescers is increased. In some preferred embodiments, the coalescers are arranged in a bank with free flow fluid paths between the coalescers in the bank, each of the paths being closed by a baffle on one end and open on an opposite end, and the baffles are arranged such that the open and closed ends of paths alternate. In other preferred embodiments, the coalescers are arranged in a tubular fashion and fluid flows from the outside surface of the tube through the coalescers and out a central path.
