Vertical cutting dryers function and High performance

Vertical cutting dryers are a high-speed vertical centrifuge that achieves maximum liquid/solid separation in large volumes. Vertical cutting dryers are one of the industry’s best performing and most dependable cutting dryers.

Function of vertical cutting dryer:

A vertical cuttings dryer can reduce liquid content to 5% with less maintenance costs. Vertical cutting dryers offer a waste management solution to effectively clean and dispose of drilling solids and maximize drilling fluid returns specific to operational needs.

Its high capacity processing provides substantial reduction to the oil-on-cuttings ratio to help meet regulations for waste disposal. Maximum separation of solids and liquids can be achieved. Increased separation means increased fluid recovery, lower cost of replacement fluid and minimal waste to be transported and disposed of going straight to your bottom line.

Versatility and high performance:

Drill cuttings are conveyed from the shakers to the VERTI-G cuttings dryer through a variety of site-engineered conveyance systems, including gravity feed, pneumatic transfer via CLEANCUT cuttings collection and transportation system, vacuum transfer and screw conveyors.

Vertical cutting dryers provides its operators an advantage for environmental and economic reasons. Vertical cuttings dryers are a necessity for industries where increased regulations on cuttings discharge are prevalent.

Vertical cutting dryer used for drilling cutting management

DC Vertical Cuttings Dryer is used in the drilling industry for recovery oil from the drilling cuttings.In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.

Unlike the first Generation and traditional Vertical cuttings dryer, DC Solids Control has improved the Vertical cuttings dryer with a patented scraper system inside the basket screen, and a high pressure air knife system is fitted to assist in continues cleaning of the screen for the vertical cuttings dryer while working.

This reduces the downtime for cleaning the vertical cuttings dryer screen. And this featured design cuttings dryer make it possible for water based drilling mud system cuttings drying which has significantly gives better drying performance than the linear motion shale shakers. The high torch completed Sun-Wheel Gear box unit ensures
the second generation vertical cuttings dryer to run more reliably than the gear driving system.

The VFD control system allows the vertical cuttings dryer to run at different G force and different differential speed to handle the drilling cuttings in proper conditions. The combined drilling cuttings picking up augers allow the drilling cuttings dryer to sit at a relatively lower profile and make it easier for the set up
of the feeding screw conveyor.

Vertical Cuttings Dryers Improve Mud Recovery & Solids Control System Performance

Modern drilling rigs are continuing to set standards by drilling deeper, faster and longer. As such, the oil and gas industry has seen a substantial increase in the volume of waste solids and liquids being generated from the solids control system.

here has never been a more critical time to manage drilling fluid and the associated wastes as an integral and inherently inseparable element of an effective solids control system. This is especially the case when a properly deployed vertical cuttings dryer (VCD) can significantly reduce waste disposal costs, dramatically lower whole mud losses within those wastes, and improve the overall quality of the drilling fluid by allowing the shale shakers and centrifuges to be used at their full operating potential.

Common flow-line shaker cuttings can maintain an oil-on-cuttings (OOC) or water-on-cuttings (WOC) moisture content as high as 25 percent. As such—and on a conservative basis—an average well will lose approximately 5 gallons per minute of drilling fluid with the discarded flow-line shaker cuttings.

Decanter centrifuges and VCDs share several similarities; however, their objectives are quite different. Centrifuges are deployed to cut waste solids from the liquid stream. The cut is usually called the underflow (also solids discharge or cake), and the cleaned liquid stream (or centrate) is usually called the overflow.

Cuttings dryer equipments used in drilling waste treatment

Drilling waste treatment is for processing and recycling drilling solid generated in the process of drilling, and reaching the environmental emission standards of the countries and regions eventually, it can effectively avoid the pollution of environment, also can save drilling fluid materiasl and reduce the cost of drilling fluid. At present, there are various types of drilling waste treatment methods and devices which have the different treatment effects. But for the domestic and foreign major site conditions in China, drilling waste removal is the most important and the most commonly used of drilling waste treatment methods.

Dry drilling waste removal refers to dewatering drilling waste by special equipment, and make the content of oil and water in the drilling waste decreased effectively, so that the drilling waste reached the statutory emission standards. Two kinds of key equipments in the dry process of drilling waste are as following:
