Abstract:
1. An apparatus for conditioning feed gas, comprising: a pressure vessel; a pre-heater heater element housing at least partially located within the pressure vessel, having an inner passage with an inlet for connection to a source of feed gas and an outlet for delivering the feed gas into an interior of the pressure vessel; at least one electrical heater element located within the inner passage of the pre-heater heater element housing for increasing the temperature of the feed gas as it flows through the pre-heater heater element housing; an expansion valve for reducing the pressure of the feed gas as it flows from the pre-heater heater element housing so as to initiate condensation; a super heater housing at least partially located within the pressure vessel and having an inlet within the interior of the pressure vessel, the super heater housing having an outlet leading exterior of the pressure vessel; a filter within the interior of the pressure vessel in a flow path leading from the pre-heater heater element passage housing to the super heater housing for removing condensate from the feed gas; and at least one electrical heater element in the super heater housing for heating the feed gas; wherein: the pre-heater heater element housing is located within an outer housing, defining an annular passage between the pre-heater heater element housing and the outer housing; and the expansion valve is located at a junction between the outlet of the inner passage and an inlet of the annular passage.
