A.
无硫或微含硫天然气 H2S和CO2含量符合管输要求,不需要净化The content of H2S and CO2 in sulfur-free or slightly sulfur-containing natural gas meets the requirements of pipeline transportation and does not require purification;
B.
低含硫天然气 H2S含量约为0.0001~0.5%(体积)H2S content of low-sulfur natural gas is about 0.0001 ~ 0.5% (volume);
C.
中含硫天然气 H2S含量约为1~1.5%(体 积),CO2含量约为6~8%(体积)H2S content of natural gas containing sulfur is about 1-1.5% (volume), and CO2 content is about 6-8% (volume).;
D.
高含硫天然气 H2S含量一般为4~8%(体积)high sulfur natural gas:H2S content of high-sulfur natural gas is generally 4-8% (volume)
