Crucible/Pot Melting Furnace delivers low fuel costs, superior fuel efficiency, land extremely close temperature control. Gas-fired crucible/pot melting furnaces are ideal for melt-and-hold at the casting station or to charge into holding furnaces for die, permanent mold or sand casting of aluminum, zinc and non-ferrous metals.

Crude oil is a naturally occurring liquid found in underground. It is a mixture of hydrocarbons of various lengths. It may contain other nonmetallic elements such as sulfur, oxygen, and nitrogen. It is usually black or dark brown but varies greatly in appearance, depending on its composition. Crude oil may also be found in semi-solid form mixed with sand.

Crude oil processing is the process where crude oil is produced, water that is co-produced with the oil is separated, and the oil is stabilized to the desired RVP by flash vaporization of light hydrocarbons. Some salt remains in this crude in the form of brine and solid particles. Desalting of the crude oil is normally considered a part of the crude distillation unit (CDU) since heat from some of the streams in the CDU is used to heat the crude in the desalting process. First, water is mixed with the crude to dissolve salt crystals and to dilute the brine already present in the crude. The crude is further heated by exchange with other streams and finally passes through a fired heater where it is heated to the temperature desired for introduction into the atmospheric distillation column.

Natural gas processing consists of separating all of the various hydrocarbons and fluids from the pure natural gas, to produce dry natural gas. The process of fractionating and refining crude oil can be very complex depending on the mixture of hydrocarbons, presence of sour gas, and the density and viscosity of the crude and its various fractions. During the processing, the mixtures and individual components have to be pumped through chemical reactors and refining equipment.

The first steps in the petroleum refining process are to desalt the crude petroleum and separate the crude into its various petroleum fractions using distillation. It removes corrosive salts from the crude petroleum by mixing heated crude with water. The crude petroleum and desalter water are separated using electrostatic separation and demulsification to break the emulsion and separate the two phases.
