Process for the transportation of acid gases in natural gas liquids streams

Patent ·
OSTI ID:5903178

Phillips Petroleum Company has developed a process that not only prevents air pollution by venting sulfur dioxide in the field but also avoids the need to install an uneconomical, inefficient, and undersized sulfur-recovery facility near the field natural gas source. The procedure calls for fractional separation of a sour field natural gas stream, dehydration and transportation of the resulting acid-gas stream and the natural-gas-liquids stream, and the recovery of the elemental sulfur contained within the dehydrated acid-gas and natural-gas-liquids mixture. In this manner, the acid-gas content of the wellhead gas stream can be transported from the natural gas processing plant to a distant process center for sulfur recovery under economical process conditions. The procedure transports the acid-gas components via existing natural-gas-liquids lines.
