What is Coke Jaw? | Restore Detox Centers

We tend to grind our teeth in our sleep or subconsciously during the day. But those who use cocaine experience heightened symptoms. The drug leads to an increase in abnormal teeth grinding motions. That leads to worn-down enamel, cavities, and brittle or broken teeth. Bruxism is also the top cause as to why people feel jaw pain after coke exposure.

Coking Process - an overview | ScienceDirect Topics

In the process, the reactor/devolatilizer receives heavy oil, extra heavy oil, and tar sand bitumen from a fired heater at a temperature of 450–535°C (850–1000°F), similar to the heater discharge temperature from the heater in a delayed coke plant. The feed flows directly into one end of the horizontal reactor/devolatilizer.

Coal Tar and its Distillation Processes – IspatGuru

In the process of coal carbonization the constituents of the tar escape from the coke ovens in the form of vapour, with a little solid free carbon (C) in an extremely finely divided state. The tar is precipitated in the hydraulic main, in the condensers, and scrubbers etc., in a liquid state, at the same time as the ammoniacal liquor is formed.
