ABSTRACT:
An elongate mercaptan injection apparatus is disclosed. From the remote end, there is an external fitting for connection with a supply line of liquid mercaptan. It communicates serially with an internal check valve captured in a chamber. The check valve includes a spring and ball cooperative with a valve seat. Through the check valve, the liquid mercaptan flows into an elongate hollow tubular member which is sealed externally with a number of fittings to prevent leakage. It extends to the interior of the pipeline through a fitting which seals to the wall of the pipeline. On the interior, it connects with an elongate hollow member packed with particulate material. A number of transverse openings provide cross ventilation so that flowing natural gas is able to pass through the particulate material. The liquid mercaptan is provided to the surfaces of the particulate material to provide an enhanced area which is moistened by the mercaptan liquid, and the flowing natural gas vaporizes the liquid to provide the proper odorization.
