Storage Methods And Functions Of Storage Containers

Nov 03, 2017

LPG storage methods can be based on the storage scale, technical and economic rationality, such as comprehensive consideration of the situation, generally have: room temperature pressure storage. Liquefied petroleum gas is very easy to dissolve at ambient temperature, and its storage equipment is equipped with spherical tank, horizontal tank and other type pressure vessel. Cool down and buck storage.Storage Containers 

Temperature is generally 0~15c, the pressure in the tank is generally 0.2 ~ 0.5 MPa. Low temperature and pressure storage. Liquefied petroleum gas at low temperature (such as propane in -42.7C, isopropyl butane at -12.8C), saturated vapor pressure is close to normal pressure (less than 10,000 kpa) and can be stored in a thin-walled container.Storage Containers

Low temperature and pressure storage investment less, steel consumption is low, but the need for refrigeration equipment and low-temperature steel, tank wall insulation, management and operating costs are high.Storage Containers

The critical temperature of methane is low, so the liquefied natural gas is stored at low temperature and pressure, and the storage temperature is -162c. Because of low liquefaction temperature, deep freezing technology is needed. The principle of direct regeneration is simple, but the screening process is more complex.Storage Containers 

It is divided into "closed" and "not closed" two kinds. The so-called "closed" (such as HDPE milk bottles after recycling after processing back to milk bottles), that is, in the regeneration process of adding a large number of fresh similar resins, about 90%, through this method of production of products in the use and mechanical characteristics of the operation with the fresh resin products no obvious distinction, good regeneration performance.Storage Containers

"Non-closed" (such as the use of HDPE milk bottles after recycling to make the laundry use of HDPE detergent bottles, and then recycled again into plastic box) that is, direct processing and cleaning, without or less use of fresh resin, in the mixed engineering to add a number of additives to regulate the physicochemical properties of resin, The mechanical properties of recycled plastic products are lower than those of fresh resins due to the aging of materials during the last use and in the process of reprocessing.Storage Containers
