General Kinematics (GK) was awarded a new contract for improvements at a leading refinery in South Eastern Asia during the summer of 2018. After researching ways to improve current processing and considering an alternative to complex silo de-watering systems, GK’s patented vibratory dewatering conveyor technology was selected. With this new system, the refinery will increase pet coke de-watering capacity, enable higher production rates, and require minimal usage of valuable refinery space.
The previous process involved removing the pet coke from a deep pit and placing it upon a sloped pad for drainage. Following an extended static drainage period, the pet coke was removed and transported to the coke crushing and materials handling system for storage. This process inhibited a production increase and, after reviewing the available technologies, the GK de-watering conveyor was selected. GK’s vibratory process technology will enable the refinery to lower its clamshell into a water-inundated pit and discharge wet pet coke directly into the GK de-watering conveyor where excess water is removed and returned to the pit prior to crushing. The de-watering conveyor also meters the clamshell surge load to the crusher to prevent overloading the conveyor belt take away system to storage.
Vibratory de-watering technology will enable the refinery to increase its production by approximately 25% with a much smaller footprint, shorter installation and commissioning time, and at a much lower cost than the other technologies considered.
General Kinematics’ pet coke de-watering method was developed in response to an overwhelming industry need for a simplified solution to pet-coke de-watering. After research and development along with extensive field testing, patents for both the design of the GK vibratory de-watering conveyor and the GK de-watering method are documented under patent number 7,108,793 and patent number 7,186,347.
The GK vibratory de-watering conveyor technology is proven in installations operating for over a decade in North America and will enable a significant production increase with lower residual moisture content and a substantial reduction in pet coke fines.
Installation and commissioning of the GK de-watering conveyor is scheduled for late summer 2019 with full production in early fall.
