2. Although December is still the traditional consumption season for the LNG market, the "peak season" trend is obvious. In addition to the weak base, the international spot and futures markets are weak, exacerbating market pessimism. Generally speaking, there is still downward expectation in the future Northeast LNG market, with the bottom line further below November. Traders are advised that they should wait and see and come in as needed.

1. LPG is a colorless volatile liquid obtained by liquefying natural gas or oil by pressurizing and cooling it in a refinery. It is prone to spontaneous combustion. When the content of the air reaches a certain concentration range, it can explode under fire.
2, the main components of LPG obtained from refineries are propane, propylene, butane and butene in one or two, also mixed with a small amount of pentane, pentene and a small amount of sulfide impurities. If the LPG is to be further purified, the oxysulfides can be absorbed and removed using an alcohol-amine absorption tower, and the excess sulfides are eventually washed with alkali.
3. LPG obtained from natural gas is essentially free of olefins. LPG consists mainly of hydrocarbons, the main components of which are propane, butane and other alkanes. Of course, there are standards for LPG composition. Not all substances composed of this combination can be called LPG. Only if the ratio of propane to butane is more than 60% can it be called LPG.
4. Of course, not all standards are the same. In foreign countries, their regulations on LPG are relatively flexible. Their definitions require adjusting the composition of propane and butane according to seasonal changes. However, as long as LPG is currently used for domestic purposes in China, there is no such concern. We need to develop further and more detailed proportionality rules for LPG combination standards if they are to apply to the industry.
LPG head gas along with fuel has been widely used in people's lives because of its high calorific value, smokelessness, no carbon residue and ease of operation. In addition, LPG is also used for cutting metals, baking agricultural products and baking industrial kilns.
I hope it can help you.
