Liquefied petroleum gases disposal

Typical refinery producfs include (1) nafural gas and liquefied petroleum gas (LPG), (2) solvent naphtha, (3) kerosene, (4) diesel fuel, (5) jet fuel, (6) lubricating oil, (7) various fuel oils, (8) wax, (9) residua, and (10) asphalt (Chapter 3). A single refinery does nof necessarily produce all of fhese producfs. Some refineries are dedicated to particular products (e.g., the production of gasoline or the production of lubricating oil or the production of asphalt). However, the issue is that refineries also produce a variety of waste products (Table 4.1) that must be disposed of in an enviromnentally acceptable manner. 

DISPOSAL AND STORAGE METHODS may be subjected to ultimate disposal by controlled incineration may be stored in liquefied form under its vapor pressure at normal atmospheric temperatures both above and below ground refrigerated liquid storage at atmospheric pressure may be used systems are closed and insulated, and the liquid petroleum gas vapor serves as the refrigerant for the system as it is circulated through pumps and compressors may also be stored in pits in the earth capped by metal domes, and in underground chambers. 

Disposal of liquefied petroleum gases, as with other gases, should be undertaken only by personnel familiar with the gas and the procedures for disposal. Contact the supplier for instructions. In general, should it become necessary to dispose of liquefied petroleum gases, the best procedure, as for other flammable gases, is to bum them in any suitable burning unit available in the plant.
