The liquid additive skid streamlines the process of adding chemicals into oil- and water-based mud systems by providing a single point of contact for liquid chemical feeding and injection jobs. It enables accurate, automatic, high-speed dosing of liquid chemicals into the mud mixing system for increased job flexibility and ease of use. The operator controls and monitors operations using a touchscreen mounted on the skid’s LCP. Operating parameters are set using the LCD touchscreen mounted on the skid LCP. An information area on the LCP displays real-time system status whenever the system is running. The liquid additive skid filling lances are connected to a flexible hose using a quick-connect valve for fast and easy changes. The unit is driven by two VFD-controlled hose injection pumps, each with a pumping capacity of up to 449 galUS/h [1,700 L/h]. A flow switch and a pressure switch on each of the chemical liquid lines guarantee accurate, automatic, high-speed dosing of chemicals.
