Skid-mounted centrifuge for heavy crude oil dehydration
X20
Centrifugal dehydration of heavy crude oil
The Alfa Laval X20 centrifuge is a purpose-built, high-capacity
process centrifuge. The design is an evolutionary development
of the highly reliable Alfa Laval nozzle bowl disc stack
centrifuge, which has been used for synthetic crude oil dehydration
in Canada since 1978.
The X20 centrifuge is mounted on an offshore skid, complete
with process and utility piping, instruments, valves and
controls to form a functional process system. The system is
suitable for use in hazardous areas on a Floating Production
Storage and Offloading (FPSO) facility.
The X20 centrifuge can treat crude oils with an API down to
11.5. It can deal with considerable variations in feed composition
and constantly obtain a pipeline specification oil quality.
The need for demulsifiers and heat is greatly reduced compared
with conventional technology.
Features and benefits
• Robust, compact design with automatic operation
• Easy maintenance, in which the bowl and bearing parts can
be removed as a complete assembly on site
• The patented OPTIPHASER™ automatic oil/water interface
system for rapid, easy on-line optimization of the separation
process
• The patented OPTIFLOW™ inlet device for minimal droplet
splitting of the feed
• Can easily be rebuilt for produced water de-oiling service
• The skid is built in accordance with Zone 1/Class 1 Div 1
specifications and complies with the ATEX regulations Zone
1 and 2.
The X20 can process up to 25,000 bpd (2,750 US gpm,
170 m3/h) of heavy crude oil with water content between
0 and 50%.
