A chemical injection pump is used to inject methanol or ethylene glycol into a fluid at the upstream of choke manifold to prevent the hydrate of formation fluid icing up due to the pressure drop, increases the reliability of the well test system and the pressure drop range above / below the choke, to restore the oil (gas) well to normal operation.
It injects liquid chemical with accurate injection volume in the processing. The chemicals injected are usually methanol, ethylene glycol, preservative, deoxidizer, drilling fluid additive (caustic soda and liquid polymer) and defoamer. In the process of water treatment, add chemicals to tap water, waste water and sewage, can also be used for the quantitative transportation of reaction materials to a high pressure reaction kettle.
Application
Well testing of HPHT wells where considerable pressure drops are occurring.
Well testing or maintenance operations.
Specification
Working Pressure: 10,000PSI, 15,000PSI.
Air Supply Pressure: 100 - 120 PSI.
Inject Capacity : 10 - 19 L/hr
Chemical injection skids inject exact amounts of chemicals and reagents into a system at required temperatures, pressures and flow rates. The chemicals also help safeguard the system from corroding quickly and forming wax, foam, scales and hydrates. Emulsion breakers induce sharp and fast separation of water from oil as well.
Most chemical injection skids deliver concentrated reagents at specific volumes to ensure bulk concentrations in the main process line are maintained. A complete system includes a chemical storage tank, two 100% metering/dosing pumps, tubing, valves, a calibration column and filtration.
Online instrumentation monitors the chemical strength, pump rate and dilution water flow rate in the systems. Those items’ parameters are controlled through valves that receive signals from a programmable logic controller.
