Abstract: The invention relates to an examination process for replicating hydrate forming conditions in a gas pipeline and monitoring the effect of a low dosage hydrate inhibitor (LDHI) in suppressing hydrate formation at temperatures encountered in gas pipelines for dynamically determining LDHI feed rate for inhibition of hydrate formation comprising the steps of: diverting from a gas well a sample gas stream at a preselected rate; introducing the diverted gas stream into a gas conduit through an inlet of the gas conduit; feeding LDHI into the diverted gas stream at one or more predetermined rates to produce a LDHI-containing gas stream; introducing the LDHI-containing gas stream into a coolable portion of the gas conduit, which coolable portion is provided with pressure sensors along the coolable portion; cooling the LDHI-containing gas stream passing through the coolable portion of the gas conduit to a predetermined temperature; and monitoring pressure of the LDHI-containing gas stream passing through the coolabl

Abstract: The invention relates to an examination process for the in situ determination of rate of feeding an inhibitor into a gas pipeline for preventing hydrate formation comprising the steps of: taking gas in situ from a gas well through a gas pipeline having an inlet, feeding the inhibitor into the gas pipeline, carrying the gas comprising the inhibitor to a coolable portion of the gas pipeline and cooling it there to a given temperature, measuring pressure difference between at least two points of the coolable portion, and determining from a drop of pressure hydrate formation at the given temperature.
