LINEER CHLOR ALKALI PLANT PROJECT DESCRIPTION
The plant will produce Caustic Soda, By-products-Chlorine gas and Hydrogen gas, Sodium Hypochlorite, Hydrochloric acid duly considers all environmental requirements, stipulations, and guidelines issued by the local Environmental Regulatory Council/ Authority in Aliaga Industrial Zone at Izmir province of Turkey. Required Licence for double capacity 2x80 Metric Ton per day 100%NaOH investment and operation license, Environmental Impact Report, and Land Acquisition for full capacity has been completed. The project realization has been planned in Two Stages. The first Stage (80 Metric Tons per day 100%NaOH ) investment has been started and is now in the erection phase. The second Stage Investment area is already allocated at the same location and necessary pre-permissions are already granted by the relevant Industrial Zone management and the governmental authorities.

Chlor Alkali Applications
The main application of the chlor-alkali process is to produce chlorine, caustic soda. Primarily, chlorine is used to make chemical compounds or organic chemicals such as phosgene for polycarbonate, methyl-chloride for silicones, polyvinyl chloride (PVC), methylene chloride for adhesives, polyurethanes, sulfur chlorides for crop protection and dyes, and titanium dioxide for catalysts.
Products made from chlorine are used in a variety of sectors, which include:Construction (PVC windows, water pipes, flooring, roofing materials)

- Construction (PVC windows, water pipes, flooring, roofing materials)
- Energy (batteries, solar panels, wind turbine blades)
- Food (crop protection, thickening agents)
- Health & and personal care (bleaches, cosmetics, detergents, dental treatments/cement, deodorants, dry cleaning, textiles)
- Home Care (paints, adhesives, refrigerants)
- Paper (inks, coatings, pulp)
- Pharmaceuticals (cancer treatment)
- Safety (water treatment)
- Sport (exercise equipment, clothing)
- Technology (circuit boards, fiber-optics, semiconductors, smartphones)
- Transportation (car parts, brake fluid, anti-freeze)
- Products made from caustic soda are also used in many sectors, including:
- Construction (carbon fiber, mining, metal plating)
- Energy (oil refining, wind turbines)
- Health & and personal care (soaps, toothbrushes, anticoagulants, shampoo, vitamins)
- Household (cooking equipment, foils, doors and windows)
- Sport (bicycles, tennis rackets, sails)

The Lineer Chlor Alkali project is planned to be completed in two equal phases:
Current investment (First stage) capacity: 80 tons/day NaOH (in 100% NaOH equivalent)
First Phase Investment Capacity is 80 tons/day NaOH (in 100% NaOH equivalent)The second Phase Investment Capacity is 80 tons/day NaOH (in 100% NaOH equivalent)Total Caustic capacity is 60 tons-NaOH /day, or 56 000 tons-NaOH per year.
Both Phase 1 and Phase 2 of the Lineer Chlor-Alkali Project will be constructed on a 50,000 m2 site located at ALOSBI IZMIR.
- 1. FIRST PHASE PLANT PRODUCTION CAPACITIES
- 1.1 Caustic Soda (NaOH)
- The plant was planned to produce.
- a- Caustic Soda 50% NaOH in liquid form daily 160 tons/day, 56,000 tons/year or;
- b- Caustic Soda 99% in solid (Flake) form 80 Ton/day, 28,000 ton/ year
- Note: The plant has the flexibility to produce partially liquid form or flake form NaOH according to the market requirements.
- 1.2 Hydrochloric Acid, Hypo (Sodium Hypochlorite (15%))
- a- Hydrochloric Acid 32% liquid form HCl. Daily 205 tons/day, 71,200 tons/year
- b- Sodium Hypochlorite 15% NaOCl in liquid form daily 77 tons/day, 26950 tons /year
- Note: If the hypo (15% NaOCl is produced at full capacity some amount of NaOH (100%) and HCl should be reduced by around 10% to arrange for hypo production.
- PLANT OPERATION STRATEGY 2.1 General The plant will produce Caustic Soda in Flake form (a99% NaOH), Liquid form (50% NaOH), Sodium Hypochlorite (15%), Hydrochloric Acid (32% HCl) as a main product. The plant is suitable for continuous operation at three shifts daily. There is a flake Caustic storage warehouse suitable for storing plastic bags of around 270 tons. This capacity can be easily increased by using a temporary closed warehouse used for the construction stage. Product Storage tank's capacity for liquid NaOH (50%) is 600 tons. The product Storage tank capacity for Hydrochloric Acid (32%HCl) is 1600 tons. The product Storage tank capacity for Sodium Hypochlorite (15%) is 270 tons. Due to the above storage capacities, the plant should dispatch the products regularly to keep space in the captioned tanks for continuous operation therefore each shift should work with good cooperation with production, maintenance, and dispatch teams.
