Abstract
Methods, processes, and apparatuses for preparing and transporting bitumen. Bitumen may be prilled such that a bitumen product comprising a prill core and a non-stick coating is produced. The non-stick coating may comprise asphaltenes and the prill core may comprise bitumen, deasphalted oil, or both bitumen and deasphalted oil. The resultant non-stick coated prills have reduced adhesion to transportation vessels and other non-stick coated prills at a temperature below an adhesion temperature, facilitating transport.
