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 that 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.
