What is a Vertical Cuttings Dryer?

A Vertical Cuttings Dryer is a mechanical drying system that removes liquids (such as oil or water) from drill cuttings, sludge, and other industrial waste. Unlike traditional drying methods, a VCD uses centrifugal force and heat to separate solids from liquids efficiently.

Key Features:

• High-speed centrifugal drying – Removes up to 90% of liquid content.
• Compact vertical design – Saves space compared to horizontal dryers.
• Energy-efficient operation – Reduces fuel and disposal costs.
• Compliance with environmental regulations – Minimizes hazardous waste.

How Does a Vertical Cuttings Dryer Work?

The VCD process involves three main stages:

1. Feeding – Wet cuttings are fed into the dryer’s rotating basket.
2. Centrifugal Separation – High-speed rotation forces liquids out through screens.
3. Discharge – Dry solids are collected, while extracted liquids are processed further.

This closed-loop system ensures minimal environmental impact while maximizing recovery.

The VC700 cuttings dryer produced by Xi ‘an Kesun is used to reduce the operator’s total drilling fluid cost and limit the amount of waste disposal.

The VC700 cuttings dryer is used to recover drilling fluid directly from cuttings and weight mud from the shaker mesh to avoid loss of weight mud due to shaker failure, rig movement, or screen blockage. The VC700 cuttings dryer helps meet certain cuttings liquid discharge requirements and automatically controls the feed for solid-liquid separation. The cuttings dryer is used to recover the liquid phase drilling fluid from the cuttings by applying a high centrifugal acceleration force to the cuttings to improve the separation of liquid from the cuttings. The VC700 chip dryer can help save money on expensive drilling fluids by further purifying the expensive liquid phase that can be returned to the mud system in use.

The VC700 cuttings dryer system recovers lost mud and returns it to the in-service mud system. For diesel, mineral oil, and synthetic oil base mud, the recovery system can work well. Because it is easier to separate oil from large drill cuttings, the cuttings dryer proved to be more effective for the synthesis of oil-based mud. Synthetic oil-based mud systems also have a higher mud value, making the machine more attractive from an economic point of view. In addition, the system reduces the amount of waste and disposal costs incurred on the rig site.

The centrifuge is commonly used equipment in drilling solid control system and mud non-landing system, so what is the difference between the centrifuge in drilling solid control system and the mud non-landing centrifuge?

Drilling fluid centrifuge
Centrifuge in solid control system of drilling

The centrifuges in the drilling solid control system generally use medium-low speed centrifuges. Because the drilling solid control system uses multi-level solid control equipment, when the drilling fluid is filtered and separated from the mud vibrating screen to the true separator to the sand and mud removal machine, the mud particle size has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuge has been able to meet the needs of mud pulping.

Mud does not fall in the centrifuge system

Centrifuges in mud non-landing systems generally use high-speed centrifuges, or variable frequency centrifuges, which belong to high configuration centrifuges. The mud non-landing system is composed of drilling cuttings drying machine and high-speed variable frequency centrifuge. The mud non-landing system is located at the end of the solid control system to deal with the drilling cuttings tail slurry after the solid control system, so the drilling cuttings tail slurry has a large proportion and the solid particle size is large. Since the centrifuge is to undertake the mud after the drilling chip dryer treatment, the particle size of the mud screened by the drilling chip dryer is very large, and the requirements for the centrifuge are very high. Therefore, the use of high-speed variable frequency centrifuge is more appropriate.

The above is the difference between the centrifuge in the drilling solid control system and the centrifuge in the mud.

After the oil-based mud returns from the well through the vibrating screen, the mud liquid phase enters the circulation system for continued treatment and use, the mud solid phase enters the filter dryer (filter separator) rock chip dryer through the screw conveyor, after the filter dryer separation, the mud solid phase is taken into the rock chip box by the screw push, the mud liquid phase flows into the liquid storage tank is pumped into the vertical centrifuge for secondary treatment. The liquid phase of the mud enters the circulation system, and the solid phase of the mud is pumped into the cuttings box through the screw pump.

In the secondary treatment, the selection of a centrifugal separator must be based on the size and concentration of solid particles in the suspension, the density difference between the solid and the liquid, the viscosity of the liquid, the characteristics of the filter slag, and the separation requirements for a comprehensive analysis, the initial selection of which type of centrifugal separator. Generally, for suspensions containing particles with a particle size greater than 0.01mm (the maximum screen mesh number for the platform is 320 mesh, and the particle size is about 0.044mm), filter centrifuges can be selected; For fine particles or compressible deformation in suspension, sedimentation centrifuge should be chosen; This is also the basis for determining the position of the drill chip dryer and centrifuge in the process. At the same time, due to the suspension of compressible deformable filter slag, under a certain separation factor, the gap between the filter slag layer and the filter medium will be blocked, and the centrifuge-treated cuttings can not pass through the cuttings dryer again.
