Coking.com | » Cleaning the Coke Drum Vapor Lines Pays

Assuming a margin of $10/bbl on a 50kbd coker, the value of cleaning the vapor line at 2 psig versus 5 psig over the clean state is: 3 psig > 240 bpd+ HCGO > 876k$/year! I could be wrong, but I think you can pay the salaries for a lot of maintenance guys to do this cleaning more regularly with those profit margins.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis. It is often subdivided into semi-anthracite, anthracite, and meta-anthracite on the basis of carbon content. Anthracite is often referred to as "hard coal"; however, this is a layman's term and has little to do with the hardness of the rock.
