[quote user="Dave-the-Train"]What are petrochem feedstocks please?  You don't mean that Ronald MacD's steers are fed hydrocarbons do you? I was wondering about plastic pellet cars?  What's petroleum coke?  A coal-type fuel made from sludge or the raw material for that drink in a funny shaped bottle?  (have you seen what it does to a tooth overnight)? (I reckon that's got to be chemical...) Thanks for the info![/quote] Petroleum coke is nearly pure carbon, solid, derived from petroleum distallation and cracking residues, which is used for fuel or in the manufacture of various things such as carbon-arc electrodes and batteries depending upon its source stocks and processing.  It is not suitable for blast furnaces for smelting iron because it is too soft.  It can also be relatively high in sulfur content.  Petroleum coke is a "last-chance" product from a refinery, from heavy (long-chain) fractions of the crude or intermediate processes that are uneconomical to form into high-value products such as gasoline or diesel fuel.  Pet coke comes in varieties such as green coke, calcined coke, and needle coke.  Refineries with heavy, sour feedstocks are more likely to make pet coke than refineries with light, sweet feedstocks (sweet = low-sulfur; sour = high-sulfur; weight refers to viscosity and specific gravity). Refineries as a rule don't make plastic pellets.  Those come from petrochemical plants.  However, petrochem plants are often co-located with refineries.  Plastic pellets are shipped in high-cube covered hoppers. Petrochem feedstocks are generally liquids or gases produced by a refinery, such as ethylene, propylene, butadiene, benzene, toluene, and xylene, and their derivatives.  They are used to make plastics, fertilizer, pesticides, insecticides, synthetic fibers, and dyes, and a lot of other things, too.
