Process Instrumentation and Valves for the Chemical and Petrochemical Industries


Miller Energy provides process control instruments and valves designed to assist in higher quality yields, more efficient processes, and greater plant safety for chemical processing and petrochemical refining manufacturing facilities. 


The Chemical Industry


The chemical industry is key to industrial production. It transforms the raw materials of animals, vegetables and minerals into a host of products used by both the industrial and domestic customers. Lightweight and durable plastic products contribute to fuel effectiveness in transportation, energy-saving insulation material in buildings, paints and protective coatings that extend metal and wood life, soap, shampoo and detergents maintain us clean, pharmaceuticals and disinfectants protect our health. Without vital chemicals, computers and telecommunications systems could not work.

The industry has matured using local resources such as salt, coal, lime, vegetable products and animal fats. It is now a worldwide sector that mainly uses natural gas and oil fractions such as naphtha as the main raw materials. There is a strong awareness of the need to substitute fossil resources both as raw materials and for process energy with sustainable options.

The Petrochemical Manufacturing Industry


The sector produces petrochemicals which are petroleum and natural gas chemicals (organic compounds not burned as fuel). Ethylene, propylene, butylene, benzene, toluene, styrene, xylene, ethyl benzene and cumene are key products. These products are fundamental construction blocks in the manufacturing of consumer products, automotive parts and numerous sustainable and unsustainable goods. These products are fundamental construction blocks in the manufacturing of consumer products, automotive parts and numerous durable goods. This sector does not include organic compounds such as ethyl alcohol and inorganic chemicals such as carbon black.

Olefins and aromatics constitute the building blocks of a large variety of products, including solvents, detergents and adhesives. Polymers and oligomers used in plastics, resins, fibers, elastomers, lubricants and gels are built upon olefins.

Hazardous Areas: Division and Zone Classification System

Hazardous area
Hazards areas are associated with flammable
vapors or gases, ignitable fibers, and combustible dusts.
Hazardous areas refer to locations with a possible risk of explosion or fire due to dangerous atmosphere. The hazards can be associated with flammable vapors or gases, ignitable fibers, and combustible dusts.

Different hazardous area classifications exist in the North America and Europe. Generally, the National Electric Code (NEC) classifications govern hazardous areas in the US. While in Europe, hazardous area classification has been specified by the International Electrotechnical Commission (IEC).

Below is a description of the Division and Zone classification system.



CLASS
NATURE OF HAZARDOUS MATERIAL
CLASS I
Hazardous area due the presence of flammable vapors or gases in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include natural gas and liquified petroleum.
CLASS II
Hazardous area due the presence of conductive or combustible dusts in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include aluminum and magnesium powders.
CLASS III
Hazardous area due the presence of flammable fibers or other flying debris that collect around lighting fixtures, machinery, and other areas in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include sawdust and flyings



Division groups hazardous areas based on the chances of an explosion due to the presence of flammable materials in the area.

DIVISION
LIKELIHOOD OF HAZARDOUS MATERIAL
DIVISION 1
Areas where there is a high chance of an explosion due to hazardous material that is present periodically, intermittently, or continuously under normal operation.
DIVISION 2
Areas where there is a low chance of an explosion under normal operation.


Group categorizes areas based on the type of flammable or ignitable materials in the environment. As per NEC guidelines, Groups A to D classify gasses while Groups E to G classify dust and flying debris.
GROUP
TYPE OF HAZARDOUS MATERIAL IN THE AREA
GROUP A
Acetylene.
GROUP B
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value equal to or less than 0.40
  • Maximum Experimental Safe Gap (MESG) value equal to or less than 0.45 mm
  • Combustible gas with more than 30 percent volume
Examples include hydrogen, ethylene oxide, acrolein, propylene oxide.

GROUP C
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value between 0.40 and 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include carbon monoxide, hydrogen sulphide, ether, cyclopropane, morphline, acetaldehyde, isoprene, and ethylene.

GROUP D
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value greater than 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include ammonia, gasoline, butane, benzene, hexane, ethanol, methane, methanol, natural gas, propane, naphtha, and vinyl chloride.

GROUP E
Area contains metal dusts such as magnesium, aluminum, chromium, bronze, titanium, zinc, and other combustible dusts whose abrasiveness, size, and conductivity present a hazard.

GROUP F
Area contains carbonaceous dusts such as charcoal, coal black, carbon black, coke dusts and others that present an explosion hazard.
GROUP G
Area contains combustible dusts not classified in Groups E and F.
Examples include starch, grain, flour, wood, plastic, sugar, and chemicals.


NOTE: This post serves only as a guide to acquaint the reader with hazardous area classifications in the USA. It is imperative to discuss your instrumentation, valve, or process equipment requirement with a qualified applications expert prior to installing any electrical device inside of any hazardous area.
