Industry gets a chance to get some work done and test a student for an extended period before making them a permanent employee. This project is an organizational study at THE TRAVANCORE COCHIN CHEMICALS LIMITED, COCHIN, KERALA. The period available for the study was 31day.

The objective of the organization study includes the following: To understand the organizational structure and the working of the various functional departments. To have an exposure to the work environment.

To understand the overall performance of the company.
To make an analysis of the organizations performance.
To study the relevance of TCC on chemical industry field in Kerala

It is an overall operation framework, which help to collect the required data. The methodology used in the study involves the collection data through primary and secondary means within the given time period. • PRIMARY DATA: It refers to the first data collected from primary sources .The primary sources of data collection were direct personal interview with managers of concerned department, official staff and workers of the company. • SECONDAY DATA: Data which are not originally collected but rather obtained from published or unpublished sources includes: 1: Company record

2: Annual records
3: Official sites of the company
4: Internet

The study was to get a general awareness of the functioning of the various departments and management of TCC Ltd. The period available for the study was one month. Since there were many departments, it was impossible to conduct a deep study on each department due to lack of time. There were many departments like operation, marketing, finance, human resource development, materials, engineering, project etc. The information from these department help to analyze the strength, weakness, opportunities and threats of the company

TCC was established in 1950 through pioneering efforts of Messer’s Seshasayee Brothers Travancore Limited. The company was originally started as Travancore of Mettur Chemicals .It was the first mercury cell plant and hence happened to be the first manufactures of Rayon Grade, caustic soda in the country. TCC was the biggest NaOH manufactures in India at that time.TCC is the only caustic soda manufacture in Kerala.


TCC is a large chemical industry; as such accurate data regarding the internal affairs of the company are not easily available.

The available data is not sufficient to get the desired result.


In the international scene, the increased production of paper, aluminium, soap and detergent naturally leads to increased requirement of caustic soda in the world scenario. The green peace movement in seeking the phase out of chlorine usage, especially the CFC compounds. This has resulted in closing down of some of the chlorine industries in Europe and North American countries. With the drop in international production, the international price of caustic soda is steadily growing up. The caustic which was sold for 50$/ tone has grown up to the 300$/ tone now.

The international markets are opening in the context of demand supply prevailing from time to time, situation of surplus and shortage are cyclical as a result of which international prices tend to be highly volatile. Though the demand for chlorine is growing fast, the demand of caustic soda is not so promising. Hence the units in the gulf and western countries are selling caustic soda at a cheaper price. MAJOR COUNTRIES PRODUCING CAUSTIC SODA


In India caustic soda is produced by electrolytic process. The manufacture of caustic soda started during 1940 .The growth was slow during 1960 but after that the growth picked up substantially. Today there are 38 industries manufacturing caustic soda of which 40 are organized sector and the rest belong to the unorganized sector. The total installed capacity of all these units put together comes to about 17, 50,000 tones/annum. Indian Chlor-alkali industries follow membrane cell technology mostly.

This is highly beneficial because cell membrane technology is more efficient when compared to mercury cell technology. India was a net importer of chemicals in early 1990s, but has now become a net exporter due to implementation of many large scale petrochemical plants like Reliance, ONGC etc. and also because of tremendous growth of exports in sectors like bulk drugs and pharmacy, pesticides, dyes and intermediates MAJOR SOUTH INDIAN CHLORA-ALKALI UNITS

The company was registered under the name Travancore Mettur Chemicals (TMC) in 1950 as a joint venture between the FACT and METTUR Chemicals. The idea was to supply hydrogen chloride gas to FACT for making ammonium chloride for their newly set up ammonia plant. As it was post second world war period, the TMC could not raise sufficient fund to take delivery of equipment arrived in Cochin port knowing that chlor alkali industry is being set up to other companies. (M/S Hindustan Insecticides LTD and other companies and M/S Indian rax Earth LTD ) have started setting up the their plants at udyogamandal with the hope to get chlor alkali product for further processing.

The financial problem of TMC was taken up by then Travancore Cochin State Government .As the problem of TMC could affect three other companies, Travancore State Government gave massive financial statements to TML and with that company was renamed as Travancore Cochin chemicals LTD in 1951 commercial production started in 1954 with 20 tons per day caustic soda production capacity. The technology employed was mercury cell technology. The installed capacity was increased stage wise to 160 TPD employing mercury cell technology .In 1997 TCC commission a 100TPD caustic soda plant employing membrane cell technology from Asahi glass company, Japan. In 2002the capacity of AGC plant was enhanced to 125 TPD. In 2004 the last mercury cell plant was decommission .In 2005 and 2006 a 25 TPD capacity membrane cell plant each were installed and plants were supplied by M/S uhde company Germany. The total installed capacity at present is 175 TPD caustic soda.TCC also has a 100 TPD continuous caustic fusion plant flakes production plant and 45 TPD soda bleach plant.

There are three plants involved in the electrolytic production process of thecompany. 1. AGC Plant

This plant is designed by ASAHII GLASS COMPANYLIMITED,TOKYO, JAPAN. The plant was commissioned on 29thmay 1997. Theproductsare Caustic Soda , commercial Hydrocloric Acid, liquid Chlorine andSodableach. The plant consists of 20 electrolyzes. The plant has 125 TPDCausticSoda production capacities.

2. UHDE 1 Plant
The plant is designed by UHDE, Germany. Theplantwascommissioned in 2005. The plant has a production capacity of 25 TPD of Caustic Soda. It consists of one electrolyze with 54 elements. 3. UHDE 2 Plant

This plant is also designed by UHDE, Germany. The plant wascommissioned in 2006. The plant has a production capacity of 25 TPD of CausticSoda. It consists of one electrolyze with 54 elements. RAW MATERIALS USED

Raw materials used in the production process in TCC are
1. Common Salt (raw salt)
2. Electricity
3. Water

The technology used by TCC is Membrane Cell Technology which is environment friendly and energy efficient technology.

The process followed in production by TCC is electrolysis of Brine.PROCESS DESCRIPTIONBrine (solution of raw salt & water) saturation & purification process are common for AGC,UHDE 1 and UHDE 2 plants.

1. Brine saturation and primary purification
Sodium Chloride or row salt is fed intothe saturator using the bucket elevator, where it set mixed with the Chlorinedecomposed,depleted Brine. This saturated Brine from the saturator goes toprecipitation tanks A & B and a mixer tank where Barium Carbonate Soda Ash andCaustic Soda are added respectively to remove Sulphates, Calcium and Magnesium.

Impurities as precipitates.the Brine along with the precipitates then goes to theclarifier where 90% of the precepts are allowed to settle. Theclarified Brine is passedthrough Anthracite filters where the remaining 10% precepts areseparated.HCL isadded to the filtered Brine tank to convert impurities to ionic form. Brine is tobeadmitted to the secondary purification system only after the desired purity level isattained.

2. Secondary brine purification
The secondary Brine purification systemconsists of our ion exchange filters. The primary purified Brine is passed through theIon exchange filters where it undergoes Ion exchange process. Ion exchangematerials are insoluble acids & bases, which when converted to salt remaininsoluble.These ion exchange materials are used in columns in which the solutionscontaining ionic impurities like Calcium and Magnesium are in contact with the resin bed. The saturated resin is then regenerated to its original state by acid alkalisolution

3. Electrolysis
The secondary purified Brine is passed through a heat exchange, fedto Brine head tank and is admitted to the anode compartments of the electrolysis.Dematerialized water is also admitted to the cathode compartment of theelectrolysis. Direct current (DC) supply is connected to the anode and cathode.During electrolysis Caustic Soda Lye is produced at cathode which is 32%concentration. Hydrogen gas is also formed at the cathode chamber. Chlorine isformed in the anode where the depleted Brine solution comes out.Caustic Soda ispumped into storage tank and Hydrogen and Chlorine gas goes to their respective treatment section

4. Chlorine treatment & liquefaction
Chlorine treatment and liquefaction involvescooling,washing filtration, drying, compression liquefaction, storage and liquidChlorine filling in the cylinders, the Chlorine from anode chamber of the electrolysisis first cooled at 30 degree celcious with the cooling tower water. Final traces of saltis removed by using a wet Chlorine filter, it is then again cooked using chilled water. After this the Chlorine gas is divided into two streams for the HCL synthesis and for liquefying. The Chlorine for liquefaction is dried using 98% Hydrochloric acid indrying tower. The dried Chlorine is compressed using acid ring compressors. Thecompressed Chlorine gas turns into liquid Chlorine storage tanks.Chlorine for the HCL synthesis unit is fed by using chlorine blower

5. H2 treatment and HCL analysis
Hydrogen gas from the electrolyser is washedwith water in washing chamber, cooled using tower water and admitted directly toHydrogen blower,after separating the condensate. The Hydrogen gas is used for theHCL synthesis and also as a fuel in the CCF plant. Hydrogen for HCL synthesis isfed to the oven using Hydrogen blowers. Here it is burned in the presence of Chlorine. The resulting HCL gas is absorbed in the water flowing down the oven to produce 31% commercial HCL gas

6. Continuous Caustic fusion
It is done in CCF (continuous caustic fusion) plant.CCF plant is mainly for concentrating 32% NaOH lye to 50% NaOH lye and then to98%-99% NaOH melts which is converted as flakes. The 32% NaOH lye is stored in generated in Ev1 is then drawn by a vaccum pump through a condenser and thusEv1 is working under vaccum and at 70-80 degree celcious. The outlet from Ev1 is40% Caustic Soda lye which is passed through Ev2 where it is evaporated to 50%Caustic Soda lye using 9 kg/-cm steam from boiler. A portion of 50% Caustic Sodalye cooled and sold. The remaining portion of 50% Caustic Soda lye is pumped toEv3 where it is heated using heat transfer salt which is a mixture of 53% PotassiumNitrate, 40% Sodium Nitrate and 7% Sodium Nitrate. In Ev3 the 50% Caustic Sodalye is concentrated to 98%-99% Caustic Soda melt which is converted as CausticSoda flakes in a flakers drum.

7. Soda Bleach preparation
Excess of waste Chlorine can‟t be disposed as a wastegas. But it has to be absorbed in dilute Caustic Soda lye to produce Soda bleach.Thus the Soda bleach plant serves also as a pollution control system.A part of 32%Caustic Soda lye, chlorine is used for the preparation of Soda bleach. The excessChlorine at the time of plant shutdown or startup and also from cylinder fillingstationgoes for Soda bleach preparation, 32% Caustic soda lye is diluted using de-mineralized water. The solution is passed through two absorbing towers, where itreacts with Chlorine gas so as to produce Soda bleach.
