Combined Storage of LPG and Natural Gas
Many European towns successfully cope with their peak gas energy demands by storing liquefied petroleum gas (LPG). The storage capacity is generally designed to cover peak demands arising during exceptionally cold winter periods. For those towns that are linked to a natural-gas grid, it has become desirable to have, in addition to the LPG storage, a dry natural-gas storage under pipeline pressure. These pressure tanks can be refilled during nighttime hours and weekends when the pipeline pressure is at its highest level. To provide adequate reserves, the dry-storage facilities need to have a capacity of about 20% of the daily average consumption, a figure which confines this method to relatively small towns.
