Abstract
A short historical and pictorial excursion on distillation will be presented and new trends in
development of distillation will be briefly discussed. The first distillation apparatus found in
Mesopotamia (today´s Iraq) comes from the period 3500 BC. A part of distillation apparatus from
Spišský Štvrtok (Slovakia) which dates back to 1500 BC (Bronze Age). It is supposed to be the
oldest part of a distillation apparatus not only on territory of Slovakia but most likely in Europe.
One of the first books on distillation written by J. French have been published in London in 1651.
Industrial application other than ethanol distillation was distillation of tar and producing
highly purified tar components such as anthracene, carbolic acid and benzene developed by Raschig
in Germany who developed also the first modern random packing Raschig rings. Petroleum
refineries were next wide application of distillation where this unit operation and related equipment
were developed to today´s matured state. The first petroleum refinery Apollo in Bratislava was
founded in 1895 and started operation in April 1896. During the first year of operation treated 23
560 ton of crude oil. A new refinery have been built in Bratislava with start up in 1957 and capacity
of 120 000 ton per year. Present two distillation units have capacity 2 million ton/year each.
New processes as extractive distillation and membrane distillation were developed and
hybrid systems with distillation combined with membrane separations are under development may
bring new impulse to distillation applications.
Bronze Age
„Bronze Age – the first golden age of Europe“ was a campaign initiated and supported by
European Council started in 1994. In the Bronze age, which lasted in Europe about 2000 years,
were led bases of European civilisation and ethnic societies in today’s Slovak territory actively
participated in this process [1]. Rich discoveries of ceramic and metallic objects document high
level of development in our territory. These were presented in very successful exhibition “Golden
age in Carpathian mountains“ prepared by Archaeological Institute of Slovak Academy of Sciences
and installed in Fiorano Modenese in Italy in 2002 and further transferred to two other Italian cities
Legnano and Bondeno and in 2004 continued in three Slovak cities including Bratislava with
catalogue [1].
The first distillation apparatus have been found in Tepe Gaura in Mesopotamia (today´s
Iraq) comes from the period 3500 BC, Fig. 18 in book [2] shown in Fig. 1. A part of distillation
apparatus from Spišský Štvrtok (Slovakia) which dates back to 1500 BC is shown in Fig. 2a and its
reconstruction (upper part was not found) [3] is in Fig. 2b. It is supposed to be the oldest part of a
distillation apparatus not only on territory of Slovakia but most likely in Europe [3]. It is obvious
that both vessels are variants of the same type of still where function and efficiency had been
maintained despite size of vessel from Spišský Štvrtok is smaller with height of bottom part of 35
cm comparing to 48 cm for vessel from Tepe Gaura [3].

Late Antiquity
Zosimos of Panopolis was an Egyptian or Greek alchemist and Gnostic mystic from the end of the
3rd and beginning of the 4th century AD. (Wikipedia)

Medieval time
The earliest distillation of Attar was mentioned in the Hindu Ayurvedic text Charaka
Samhita. The Harshacharita, written in 7th century A.D. in Northern India mentions use of fragrant
agar wood oil. (Wikipedia, history of perfume)

Arab scientists
The birth of the Arab physical sciences in the 7th and 8th centuries was one more expression
of the same breakthroughs that were happening in Arab mathematics, astronomy and geography,
driven partly by long-standing scientific traditions in the peoples who came into the Arabic
caliphate. Perhaps the Arab scientific field where the birth was most dramatic was in chemistry.
And the earliest and most powerful Arab practitioner of the new science of chemistry was Jabir Ibn
Hayyan, recruited by Caliph Harun Al Rashid to work in the early House of Wisdom in Baghdad.
Jabir Ibn Hayyan (Geber, 721-815) was a prominent Islamic alchemist, pharmacist,
philosopher, astronomer, and physicist [4]. He has also been referred to as "the father of Arab
chemistry" by Europeans. Jabir is mostly known for his contributions to chemistry. He emphasised
systematic experimentation, and did much to free alchemy from superstition and turn it into a
science. He is credited with the invention of many types of now-basic chemical laboratory
equipment, and with the discovery and description of many now-commonplace chemical substances
and processes - such as the hydrochloric and nitric acids, distillation, and crystalization that have

become the foundation of today's chemistry and chemical engineering. Jabir is also credited with
the invention and development of several chemical instruments that are still used today, such as the
alembic, which made distillation easy, safe, and efficient. He noted that boiling wine released a
flammable vapor, thus paving the way to Al-Razi's discovery of ethanol.

Al-Razi (865-925) was the preeminent Pharmacist and physician of his time [5]. The discovery of
alcohol, first to produce acids such as sulfuric acid, writing up extensive notes on diseases such as
smallpox and chickenpox, a pioneer in ophthalmology, author of first book on pediatrics, making
leading contributions in inorganic and organic chemistry, also the author of several philosophical
works.

Al-Kindi (801-873, Baghdad, Iraq) [6]
He wrote in the 9th century a book on perfumes which he named ‘Book of the Chemistry of Perfume
and Distillations’. It contained more than hundred recipes for fragrant oils, salves, aromatic waters
and substitutes or imitations of costly drugs. The book also described one hundred and seven
methods and recipes for perfume-making, and even the perfume making equipment, like the
alembic, still bears its Arabic name.
Avicenna (Ibn Sīnā, 980- 1037, Persia, Afghanistan) [7]
Avicenna created an extensive corpus of works during what is commonly known as Islam's
Golden Age, in which the translations of Greco-Roman, Persian and Indian texts were studied
extensively. Greco-Roman (Mid- and Neo-Platonic, and Aristotelian) texts by the Kindi school
were commented, redacted and developed substantially by Islamic intellectuals, who also built upon
Persian and Indian mathematical systems, astronomy, algebra, trigonometry and medicine.
In chemistry, the chemical process of steam distillation was first described by Avicenna. The
technique was used to produce alcohol and essential oils; the latter was fundamental to
aromatherapy. He also invented the cooling coil, which condenses the aromatic vapours. This was a
breakthrough in distillation technology and he made use of it in his steam distillation process, to
produce essential oils. He first experimented with the rose. Until his discovery, liquid perfumes
were mixtures of oil and crushed herbs, or petals which made a strong blend. Rose water was more
delicate, and immediately became popular. Both of the raw ingredients and distillation technology
significantly influenced western perfumery and scientific developments, particularly chemistry. As
a chemist, Avicenna was one of the first to write refutations on alchemy, after al-Kindi.
One of the first books on distillation “The art of distillation“ written by J. French have been
published in London in 1651 [8].

th
and 20
th
century
In preindustrial era until the 19
th
century, renewable raw materials were the major source of
energy and material use. During the Industrial Revolution, the use of coal increased sharply and
coal quickly becomes a key raw material in the chemical industry and energy production.
Industrial application other than ethanol distillation was distillation of tar and producing
highly purified tar components such as anthracene, carbolic acid and benzene developed by Raschig
in Germany who developed also the first modern random packing Raschig rings, Fig. 14. In the 20

century, there has been a changeover in fossil fuel sources from coal to crude oil and natural gas
due to lower prices, simpler logistics and the versatility in usage of oil and gas. Petroleum refineries
and petrochemical plants were typical with wide application of distillation where this unit operation
and related equipment were developed to today´s matured state.
The first petroleum refinery Apollo in Bratislava was founded in 1895 and started operation
in April 1896 [9]. During the first year of operation treated 23 560 ton of crude oil. Refinery was
renamed to Slovnaft in 1949. A new refinery have been built in Bratislava with start up in 1957 and
capacity of 120 000 ton per year. Present two distillation units have capacity 2 million ton/year
each.

Desalination of sea water
Scarcity of drinking water in large territories requires its production from available sources
like brackish water or sea water. One possibility is to use distillation and multi-stage flash
distillation (MSF) was developed which scheme is shown in Fig. 19. Like all evaporative processes,
MSF can produce high-quality fresh water with very low salt concentrations (10 ppm or less), from
salt concentrations as high as 60,000 to 70,000 ppm total dissolved solids, nearly twice the salinity
of seawater. In MSF, evaporation or “flashing” occurs from the bulk liquid. This minimizes scale
and is a major reason MSF has been popular for several decades. Generally, only a small percentage
of feed water is converted to water vapour in one stage, depending on the pressure maintained in
each stage. MSF plants may contain between 4 and 40 stages, but most typically are in the range of
18 to 25. Multi-stage flash plants are typically built in sizes from 10,000 m
3
/day to over 35,000
m
3
/day, with several units grouped together. MSF accounts for the greatest installed thermal
distillation capacity [10-11]. As of early 2005, the largest MSF plant in operation was in Shoaiba in
Saudi Arabi [12]. This plant desalinates seawater for municipal purposes with a total capacity
455,000 m

21th century
Historical milestones of distillation development are summarised in Table 1. In connection with
the limited availability and increasing price of crude oil and natural gas, the question now arises
how to face this situation and what raw material base will develop in the future? Biomass as a
renewable raw material could be answer [13-14]. There is a historical line of dominant resources
used from local renewable resources to coal, coal gas and tar industries to crude oil and natural gas
in petroleum refineries and petrochemical industry and recently switch to biomass in biorefineries
and other renewable resources is of increased importance.

Transformation of raw material platform to biomass will not be quick and simple. It requires
concerted cooperation of several scientific disciplines as agriculture, forestry, biology,
biotechnology, chemistry, chemical engineering, environmental sciences, but also industrialists,
strong economical and political impulse, etc. Renewable raw materials will be increasingly used in
the future. New processes have to be developed to transform biomass to fuels, energy and chemicals
in economically competitive way. This will be a challenge also for distillation especially in hybrid
systems.

New developments in distillation
Modern civilisation faces several challenges among them shortage of water in many areas,
shortage of fossil raw materials with need to switch fuel and chemical industry to renewable
resources and environmental aspects of our civilisation connected with changes of climate.
Membrane distillation
Membrane based distillation has potential to improve economy of sea water desalination.
Recent research results gives impulse for further development [19-23].
Extractive distillation of ethanol.
For fuel applications, ethanol essentially free of water has to be produced. Considering the low
concentration achieved during fermentation, a huge separation effort has to be expected. In addition,
an azeotrope is formed in this system, which cannot be further separated by simple distillation.
Entrainers, which are fed in counter-current into the separation column, are hence chosen to interact
selectively with the high-boiling component, in this case water, thus reducing its activity and
increasing the relative volatility of ethanol. A high capacity is also important to keep the column
diameter to a minimum. Entrainers enhance the separation factor, and the ionic liquid
[C2mim][BF4] is more efficient than ethanediol if similar concentrations are used. The use of an
ionic liquid entrainer reduces thus the number of plates and/or the recirculation ratio, leading to
overall reduced separation costs [24]. Ionic liquids may provide higher energy efficiency than other
methods.
Hybrid systems with distillation
Hybrid systems with distillation and vapour permeation shows promising results in
decreasing energy demand for bioethanol dewatering for fuel applications [15-18, 25]
