PROCESS FOR REMOVING HEAVIER AROMATIC COMPOUNDS FROM A LIGHT HYDROCARBON GAS STREAM

摘要

A process for removing heavier aromatic compounds, especially trimethylphenylindane (TMPI) and phthalate compounds, from a light hydrocarbon gas stream, especially a stream of natural gas, wherein said hydrocarbon gas stream is contacted with an activated carbon having a pore size distribution where at least 10 % of the pores have a diameter above 17 A. The process may be carried out in the presence of additioned odorous agents selected from sulphur compounds, e.g. tetrahydrothiophene (THT).
