Abstract:
1. A purification unit for separating hydrocarbons from a gas, comprising: a converter housing suitable for conducting gases therethrough; a catalyst material disposed therein; at least one temperature sensor; a heat exchanger; and a heat source including a heating system surrounding the converter housing adapted to heat the catalyst material from outside of the converter housing; wherein the catalyst material contains pure hopcalite which heats up sharply given an increased content of hydrocarbons in the gas; wherein a temperature of the hopcalite is determined with the at least one temperature sensor; wherein the purification unit is configured such that the gas is pre-heated in the heat exchanger by hot air from the converter housing to temperatures of 100 to 130° C., and then said pre-heated gas flows into the converter housing and through the catalyst material at a set operating temperature of approximately 150° C.; and wherein the purification unit is further configured so that when the at least one temperature sensor detects a temperature that is higher than a threshold temperature, at least one of (i) the purification unit is switched off (ii) an alarm signal is issued; and (iii) flow of the gas is cut off.
