A system and a method for removing gas field chemicals from a feed stream are provided. An exemplary method includes performing a forward osmosis on a feed stream including gas field chemicals to form a concentrated feed stream, and treating the concentrated feed stream in an electrochemical process to form treated water.

Decomposition of gas field chemicals

A natural gas (NG) processing plant and method of operating the NG processing plant including: receiving feed NG, removing acid gas from the feed NG gas via a gas sweetening unit having an amine absorber column that absorbs the acid gas, collecting an amine sample in the gas sweetening unit, removing water from the feed NG via a NG dehydration system having a column vessel that contacts the feed NG with liquid desiccant including glycol to remove the water, collecting a glycol sample in the NG dehydration system, adding reagent water and ferrozine to each of the amine sample and the glycol sample, and measuring total dissolved iron via ultraviolet-visible (UV-Vis) spectrophotometry in each of the amine sample and the glycol sample.

Measurement of iron in glycol and amine in natural gas processing

To analytically determine concentration of dissolved gases in a water pipeline, a water sample is drawn from a source carrying water with dissolved gas, through a water source port of a four-way valve. The water sample is flowed from the water source port towards a syringe port of the valve and into a syringe fluidically coupled to the syringe port to hold the water sample. Inert gas is drawn through an inert gas port of the valve from an inert gas source and is flowed from the inert gas port towards the syringe port and into the syringe. A mixture of the water sample and the inert gas is flowed from the syringe port towards an analyzer port of the valve and into an analyzer fluidically coupled to the analyzer port.

Analytical determination of dissolved gas concentration in water pipelines

A method may include transporting a water stream comprising water and a biocide from an upstream location to a downstream location, withdrawing a sample of the water stream to a sample collection and analyses system, preconditioning the sample, injecting the preconditioned sample into an online gas chromatography analyzer, measuring a concentration of the biocide in the sample via the online gas chromatography analyzer to obtain a measurement result, transmitting the measurement result to a control system, and adjusting by the control system, automatically injecting biocide into the water stream at the upstream location based on the biocide dosage requirement on either a batch, or semi-batch, or a continuous basis. A system for measuring and controlling biocide concentration in a water stream in a pipeline may include a sample probe, a cabinet heater, a filtering unit, an online gas chromatography analyzer, a control system, and an injection system.
