What Is a Propane Forklift?

Propane, tricarbonane, the chemical formula is C ₃ H ₈ , and the simple structure is CH3CH2CH3. It is usually gaseous, but is usually transported after being compressed into a liquid state. After processing crude oil or natural gas, propane can be obtained from refined oil. Propane is often used as a fuel for engines, barbecue foods, and domestic heating systems. In sales, propane is commonly called liquefied petroleum gas, which is often mixed with propylene, butane, and butene. To detect accidental leaks, malodorous ethyl mercaptan is also commonly added to commercial liquefied petroleum gas.

In 1910, Dr. Walter O. Snelling, who worked at the US Bureau of Mines, found a

1. It can be collected as petroleum gas during petroleum extraction and refining. During the cracking and catalytic cracking of petroleum fractions, a large amount of propane is also formed. Therefore, the impurities that coexist with propane include methane, ethane, butane, ethylene, propylene, and low boiling point sulfides and water.

2. During the refining, the gas produced during the distillation and cracking of petroleum is concentrated by methods such as oil absorption, activated carbon adsorption, compression and cooling to liquefy it, and fractionation at low temperature or pressure to separate propane. Unsaturated components such as propylene can be removed with concentrated sulfuric acid or hydrogenated. The sulfur-containing compound can be washed with an alkali or removed with a desulfurizing agent. The water is dehydrated with concentrated sulfuric acid, ethylene glycol, solid desiccant (such as white clay, alumina) and sodium metal, etc., and can also be removed by azeotropic distillation. Propane is generally recovered by distillation. It can also be recovered by absorption of high-boiling hydrocarbons or adsorption with an adsorbent.

3. Use liquefied petroleum gas as raw material, condense at 0 5 , remove some high boiling point impurities, and then enter the adsorber to remove water, propylene, ethylene, ethane, n-butane, isobutane Hydrocarbon impurities such as alkane, n-butene, isobutene, etc., then enter the condenser to condense propane into a liquid and separate it from non-condensable gases such as nitrogen and oxygen. The extraction rate of propane can reach more than 80%. ^[2]

Propane is often used as a fuel for barbecues, portable stoves and motor vehicles. C

Propane is generally stored and transported in liquid form. The storage and transport conditions are normal temperature and the pressure reaches the saturated vapor pressure. Design parameters of storage tank: 1800kPaA, 60 .

A dump pump or compressor is required, and some tankers have their own dump pumps. It is best to set the carburetor, which should be determined according to user requirements. If it is simple, if the amount is not large, the pressure is not high, and the length of the pipeline is moderate, the medium can use the pressure in the storage tank to press the propane into the pipeline to naturally vaporize.

Conditionally unload the truck with nitrogen pressure, unload the compressor or pump without conditions. The tanker does not have an air temperature booster. Consideration must be given to setting up air-temperature gasifiers for gasification or heating.
