Vertical Cuttings Dryer
KEMTRON Separation Technologies Seawater Flush Guns Seawater flush guns are provided in order to assist in helping to maintain steady fluid flow for seawater injection into the VCD. Vibration Switch If excessive vibration occurs during operation this unit will automatically shut off to prevent damage. Poly-chain KEMTRON’s carbon fiber poly-chain does not require a quarterly replacepement. The carbon fiber tensile cords are length stable and can withstand shock loads that frequently lead to belt failure. Continuous Duty Vertical Cuttings Dryer As our industry evolves, we are faced with an increasing responsibility to protect the environment in which we operate. Concurrently, government agencies continue to increase the limitations on the discharge of contaminated drill cuttings to the environment. To support the goals of both the industry and regulators, KEMTRON has developed a rugged Vertical Cuttings Dryer (“VCD”). Achieving Results Typical linear motion shaker cuttings maintain a liquid content on average between 15% to 25%. When properly managed, KEMTRON’s VCD will lower the liquid content below 5%. This can be done while managing 40 tons (36,000 kilograms) per hour of drilling cuttings. Easy to Use and Maintain This unit was designed to be durable and easy to use. KEMTRON’s VCD features a poly-chain which can withstand harsh environments thus not requiring a quarterly replacement. KT-4060-VCD Offshore Continuous Duty Vertical Cuttings Dryer with Seawater Flush Guns BEFORE – Drill cuttings prior to feeding through a VCD. AFTER – Drill cuttings after being processed by a VCD. 1. As referenced in EPA Compliance Cost Methodology for BAT/NSPS Cuttings Dryer Technology, performance data from 23 wells revealed that the Synthetic On Cuttings (SOC) was reduced from 11.7% to 4.15% by weight after being processed.WSM discards ranged from 6% to as low as 1% oil by weight. Based on these averages, a 65% reduction in fluid discharge can be achieved. 10050 Cash Road • Stafford, Texas 77477 • +1-888-536-8766 • www.kemtron.com KEMTRON Separation Technologies Key Features and Benefits Rugged Design Rugged proprietary wedge-wire screen basket designed to reduce blinding and frequent replacement. Rig Safety Total noise levels do not exceed 85 dB and all rotary components are fully guarded and balanced. Packaging & Customization KEMTRON’s VCD is capable of being provided as a standalone device or as a packaged system that easily integrates with existing solids-control equipment. Cuttings Handling The use of screw conveyors allows solids to enter the VCD relatively intact, therefore, providing greater separation and improved screen life. Operation KEMTRON’s VCD is fed via screw conveyor, vacuum system, or rotary-lobe solids pump from the flow-line shaker discharge. Drill cuttings are fed into the hopper and distributed along the inner wall of the screen with the aid of the rotor. The liquid phase, or “filtrate,” passes through the screen openings while the vertical scrapers scrape the accumulating cake solids towards the bottom of the VCD for disposal. The centrate gravity flows into a containment tank and is then pumped to a high speed decanter centrifuge for low gravity solids removal. Upon discharge, the dried cuttings are then safely discharged to the environment, collected for further treatment, or are staged for offsite disposal. KEMTRON’s VCD significantly improves liquid phase recovery, therefore paying for itself. Controls KEMTRON’s VCD can be operated with soft start or with a variable frequency drive (“VFD”) controller. Soft starts can be provided within a NEMA 7X explosion-proof enclosure. VFD controls are provided in a NEMA 4X enclosure and include an operator-friendly human/ machine interface (“HMI”) and programmable logic controller. KEMTRON’s in-house panel shop can customize your system, regardless of the application or the service conditions.
