When there is transfer of fluids from one company to another, the requirement of Custody Transfer Skid arises.
LACT skids are used to transfer the process fluid with change of fluid property. These skids are very precise and accurate for sales measurement and settlement of invoices. These skids come with certified flow meters for custody transfer. Their accuracy ranges from 0.05% to 0.5% of the flow.
Depending on the service, the flow measurement technology varies from Coriolis, PD, Turbine and Ultrasonic. Typically, these metering stations range in capacity from 20 m3/hr to 2000 m3/hr with a size range of 2″ to 24″ with a pressure class of 150# to 900#.
Other important components of the skid consist of instruments for pressure, temperature, density, manual or automated isolation valves, current switching valves, Prover take-off valves, flow computers normally mounted on the panel and other auxiliary piping and mechanical components, electrical fittings, structural steel, etc.
It is mainly used in the transfer of hydrocarbons such as Crude Oil, Natural Gas, LPG, Diesel Oil, etc.
