- Wood creosote, coal tar creosote, coal tar, and coal tar pitch
differ from each other in composition
- Chemical formula: Creosote is a highly complex mixture
containing hundreds of individual compounds. Although the actual
composition of creosote may vary somewhat due to differences in the
source material, when used to preserve wood creosote may only be
manufactured by the distillation of tar obtained from coal and must
conform to standards
- Coal tars are by-products of the carbonization of coal to
produce coke and/or natural gas.
- Coal tar creosotes are distillation products of coal tar
- Unlike the coal tars and coal tar creosotes, coal tar pitch is a
residue produced during the distillation of coal tar
- Creosote production falls into two
categories: distillate (100% creosote), and creosote in coal tar
solution.
- Coal tar creosote has been used as a wood preservative pesticide
in the United States for over 100 years.
- China alone has the capacity to distil 10MM metric tons of coal
tar which results in 5MM metric tons of coal tar pitch and ~3.5MM
metric tons of distillate that could potentially be blended into
creosote.
- EPA has designated coal tar creosote a restricted-use pesticide.
This means it can only be sold by companies registered with the EPA
and bought and only used by certified applicators for those uses
covered by the applicator's certification.
- Creosote has been continuously registered as a wood preservative
by the EPA since 1948.
- Coal tar creosote is a wood preservative and water-proofing
agent for log homes, railroad ties, telephone poles, marine pilings,
and fence posts.
- Creosote remains the material of choice for preserving and
protecting wooden railroad ties and continues to be an effective
treatment for wooden utility poles and foundation and marine
pilings.
- The Railroad Tie Association, as well as Creosote Council III
and other wood industry groups, are proactive in providing the
resources and tools necessary to ensure treated wood ties will
continue to serve the railroad industry for a very long time.
- Creosote or creosote/borate dual treatments are used for
approximately 98.5% of the treated wood tie market.
- The raw tar as obtained from the coke ovens is
processed or distilled to produce a variety of products. Usually the
first step in processing coal tar is to subject it to a primary
distillation to produce several fractions of cuts. In general, at
least two cuts are made. These are often referred to as chemical oil
and creosote oil. The material remaining after the removal of the
oil distillates is either pitch or a refined coal tar base.
- Indian plants have potential to produce approx
1.1 Mt of crude tar per year
- Present status of coal chemicals recovery in
India is far from satisfactory. These chemical plant (also know as
By-Product Plant) conceived and installed along with coke oven
batteries in the steel plants have become quite old and are beset
with various problems associated with process, operation and
maintenance resulting in low yield of chemicals, frequent breakdown,
increased operating cost etc.
