Abstract: An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F.
