Pumps are used to move the oil from one process to another. This chapter covers temporary storage separation and disposal as well as the types of pumps used for oil. Storage separation and disposal are all crucial parts of a cleanup operation. In several major cleanups recovery has actually stopped because there was no place to put the recovered oil. When oil is recovered sufficient storage space must be available for the recovered product. The recovered oil often contains large amounts of water and debris that increase the amount of storage space required. Several types of specially built tanks are available to store recovered oil. Flexible portable tanks often constructed of plastic sheeting and a frame are the most common type of storage used for spills recovered on land and from rivers and lakes. These are available in a range of sizes from approximately 1 to 100 m3 and require little storage space before assembly. Most of these types of tanks do not have a roof however so rain or snow can enter the tank and vapours can escape. Rigid tanks which are usually constructed of metal are also available but are less common than flexible tanks. Pillow tanks constructed of polymers and heavy fabrics are usually used to store oil recovered on land. These are placed on a solid platform so that rocks cannot puncture the tank when full. Pillow tanks are also sometimes used on the decks of barges and ships to hold oil recovered at sea. Oil recovered on land is often stored in stationary tanks built for other purposes and in dump trucks and modular containers lined with plastic. Recovered oil can also be temporarily stored in pits or berms lined with polymer sheets although this open type of storage is not suitable for volatile oils. Towable flexible tanks usually bullet-shaped .
