Liquefied petroleum gas definitely contains hydrogen sulfide, so I have a slight question: does liquefied natural gas contain hydrogen sulfide as well?

There probably isn’t any, because if there were hydrogen sulfide, the smell would be very noticeable.
LPG and natural gas do not necessarily contain sulfur; some gas field gases are sulfur-free
If the content is low, there will be a smell of rotten eggs; if the content is high, then no such smell can be detected.
Liquefied natural gas certainly contains hydrogen sulfide
Even if liquefied natural gas contains H2S, its concentration is extremely low and can be considered negligible.
Sulfides in natural gas are much lower than those in liquefied petroleum gas
It depends on the quality of the gas produced from specific gas sources at particular times; for example, the hydrogen sulfide content in the Dagang Oil Field is 1.4% (gas produced from oil fields), while it is 1.5% in the Changqing Gas Field in Inner Mongolia (gas produced from pure gas fields). The technical specifications regarding sulfur and hydrogen sulfide content for Class 1 and Class 2 natural gas are as follows: Parameter, Class 1, Class 2; Total sulfur (expressed as sulfur), mg/m3: ≤ 60, 200; Hydrogen sulfide, mg/m3: ≤ 6, 20. The information above was obtained from Baidu and is provided for reference only

The specification for sulfur removal requires levels not exceeding 10 ppm or 20 mg/m3 (both of these are values based on analysis under normal pressure), but in practice, the levels are usually below the minimum detection limit of 2 ppm.
