Why isn’t ethane used as town gas?

According to Article 3.2.2 of the \"Code for Design of Urban Gas Supply\" GB500028, it seems that the types of urban gas are limited to four categories: liquefied petroleum gas, natural gas, artificial gas, and air-blended liquefied petroleum gas. This year (2021), the price of LNG is relatively high, and some factories are considering using ethane as a substitute for LNG, as its current price is lower than that of LNG, and it also has a higher heat value per unit. This leads to a question: why don’t town gas providers use ethane as one of the fuels? Everyone is welcome to share their opinions and views. Methane is a permanent gas, while ethane is a liquefied gas. The lower limit of the explosion limit for ethane is slightly lower, and ethane is denser than air; that’s all the differences.
It can be used for natural gas extraction, but where does ethane come from? Common synthetic gases include dimethyl ether
In the extraction and processing of shale oil and gas, ethane is the main by-product.
Ethane can be used as a feedstock to crack into ethylene
It’s not just a simple replacement issue； It can be replaced, but each user needs to get a corresponding burner; otherwise it won’t work

High LNG prices are a short-term market phenomenon; in the long run, burning ethane as fuel is indeed a waste.
Ethane extraction and export have only become a thing in recent years. Ethane is more suitable as a C2 chemical raw material rather than a fuel
