An ethylene cracker is a petrochemical plant. Primarily it takes in a feed of gas hydrocarbons (dry gas, propane, butane) or kerosene (rarer). It then heats it up to about 900degrees to literally "crack" the molecules into smaller ones. After this heating, the product is a mixture of lots of different gases and some liquids. These are then separated (refined) into different products. The primary product is ethylene.

Most ethylene crackers have a hydrogenation section. This is a series of reactors which hydrogenate (add hydrogen) any acetylene turning it into ethylene. This increases the ethylene yield.
