APPARATUS AND METHOD FOR THE ANALYSIS OF GASES, IN PARTICULAR FOR THE ANALYSIS OF NATURAL GAS EXTRACTED AS SHALE GAS

摘要

An apparatus and a method for the treating gases, such as natural gas extracted as shale gas, has a heat-insulated protective housing with a stratified liquid reservoir. An outer heat exchanger outside the protective housing has a primary side about which ambient air flows as heating medium and a secondary side for cold stratified reservoir liquid to be heated and fed back to the stratified reservoir. A defined quantity of gas flows through an inner heat exchanger inside the housing and is heated to a defined gas temperature by heated stratified reservoir liquid. The cooled stratified reservoir liquid leaving the inner heat exchanger feeds back to the stratified reservoir. The heated gas leaving the inner heat exchanger flows to a gas analysis apparatus inside or outside the heat-insulated protective housing.

1. An apparatus for the treatment of gases, the apparatus comprising:
a heat-insulated protective housing; a stratified reservoir disposed in said heat-insulated protective housing and configured for accommodating and storing therein a stratified reservoir liquid in superposed layers in a plurality of temperature zones having mutually different temperatures and including a cold temperature zone and a high temperature zone; an outer heat exchanger disposed outside said heat-insulated protective housing and fluidically communicating with said stratified reservoir through a stratified reservoir liquid branch line connected to said cold temperature zone of said stratified reservoir, wherein ambient air flows around said outer heat exchanger as a heating medium for heating a defined quantity of cold stratified reservoir liquid drawn off from said cold temperature zone of said stratified reservoir, and wherein the cold stratified reservoir liquid, which has a lower temperature than the ambient air, is heated by heat exchange with the ambient air to form a hot stratified reservoir liquid at a defined stratified reservoir liquid temperature; a stratified reservoir liquid metering line disposed to conduct the hot stratified reservoir liquid from said outer heat exchanger back to said stratified reservoir into said high temperature zone; an inner heat exchanger disposed inside said heat-insulated protective housing and conducting therethrough a defined quantity of a gas to be heated, received from a gas feed line, and a defined quantity of hot stratified reservoir liquid drawn off from said high temperature zone of said stratified reservoir, received through a stratified reservoir liquid feed line, wherein the gas, which has a lower temperature than the hot stratified reservoir liquid, is heated to form heated gas at a defined gas temperature while the hot stratified reservoir liquid is cooled to form cooled stratified reservoir liquid; a stratified reservoir liquid recirculation line connected to conduct the cooled stratified reservoir liquid from said inner heat exchanger to said stratified reservoir into said cold temperature zone, and a gas discharge line connected to conduct the heated gas away from said inner heat exchanger; and a gas analysis apparatus connected to receive the heated gas from said gas discharge line.
