SYSTEM FOR MEASURING THE DEW POINT TEMPERATURE OF A GAS FLOW

摘要

The invention relates to a system (20) for measuring the dew point temperature of a gas flow flowing in a pipeline, comprising: - a measurement circuit (21) comprising at least one means for connection (22) to said pipeline, at least one means for activating the flow of the gas (24) in said circuit and one sampling means (23), - a reference circuit (25) wherein there flows a reference gas, - a detector (27) for measuring the dew point temperature by means of differential scanning calorimetry, said detector comprising two measuring lines (27a, 27b), whereof one (27a) is connected to the measurement circuit (21) and the other (27b) is connected to the reference circuit (25). The invention also relates to a reactor and a unit for producing liquid sulphur comprising such a measuring system, and a control method using this control system.
