As a derivative product in the process of petroleum refining, its price change is mainly affected by the change of crude oil price. In the past two years, due to the increase of oil production in major oil-producing countries and the oversupply of crude oil, the price has always been stable.
Since the oil production cut at the end of last year, the international crude oil price has risen steadily, and so has the price of liquefied gas. In addition, rising transportation costs and tight supply and demand at the terminal are all factors that affect the price of liquefied gas.
Under the rising oil price, all major buyers are "miserable". Take China as an example. Due to the recent rise in international oil prices, domestic refined oil prices have also risen simultaneously. On September 23rd, China's refined oil prices broke through the red line of upward adjustment, and the expected upward adjustment range was 75 yuan/ton.
Liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing, cooling and liquefying natural gas or oil in refinery. Spontaneous combustion is easy. When its content in the air reaches a certain concentration range, it will explode when it meets an open flame.
Liquefied petroleum gas obtained from the refinery is mainly composed of one or two of propane, propylene, butane and butene, and is also doped with a small amount of pentane, pentene and a small amount of sulfide impurities. If LPG is to be further purified, it can be absorbed and removed by alcohol amine absorption tower, and then the excess sulfide can be washed away by alkali.
