iron sulfide liquid hydrocarbons compressor lube oil sulfur products A filter separator differs from a standardoil and gas separatorin that it uses a natural gas filter element to remove contaminants rather than mechanical devices. Below, we'll explain: ...
Water is made up of two different elements, 2 hydrogens and 1 oxygen, so H2O is a compound. Two oxygen atoms (O2) are two elements, but they are the same element, so O2 is a molecule. Iron oxide (Fe2O3), or rust, is made up of two different elements, 2 irons and 3 oxygens...
