Propylene Glycol from Chlorine and Propylene
Propylene Glycol Operating Costs & Plant Construction Costs
This report presents the economics of Propylene Glycol production from chlorine and chemical grade (CG) propylene in the United States, via a typical hydration process. In this process, chlorine, propylene and water are combined to make propylene chlorohydrin, which reacts with inorganic base to yield the oxide. The oxide is then hydrolyzed to propylene glycol.
The report provides a comprehensive study of Propylene Glycol production and related Propylene Glycol production cost, covering three key aspects: a complete description of the Propylene Glycol production process examined; an in-depth analysis of the related Propylene Glycol plant capital cost (Capex); and an evaluation of the respective Propylene Glycol plant operating costs (Opex).
The Propylene Glycol production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Propylene Glycol plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Propylene Glycol plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

Products
Propylene Glycol. Propylene Glycol (a.k.a. Propane-1,2-diol) is a clear, colorless, non-corrosive, but strongly hygroscopic difunctional alcohol in such a way that it must be protected from exposure to the atmosphere. Unique among the glycols, Propylene Glycol has low toxicity to humans. The largest application of Propylene Glycol is in the production of polyester resins, although it also has a wide application in the food, pharmaceutical, and cosmetic industries. Propylene Glycol also has great solvent properties for several polar organic materials, such as phenols, alcohols, dyes, natural products, and even some resins. Moreover, due to its property of reducing the water freezing point, PG has been used as an option for aircraft deicing and anti-icing fluids. This commodity was first manufactured in 1859 by the hydrolysis of propylene glycol diacetate However, it was only in 1931 that it was first commercialized and used as a substitute for glycerol in pharmaceuticals.
Dichloropropane. This saturated organochloride is mostly used industrially for the manufacture of other chlorinated chemicals, and can also be used as a solvent for certain processes.
Raw Materials
Chlorine. Chlorine figures among the most important chemical commodities. It is an indispensable intermediate in the chemical industry, employed in the manufacture of a multitude of end products (e.g. materials of construction, solvents, pesticides, etc). Most of chlorine produced on commercial scale is based on electrolysis of aqueous sodium chloride (brine), which also generates caustic soda and hydrogen as co-products (chlor-alkali processes).
CG Propylene. Propylene, the main raw material consumed, is a colorless gas at room temperature. It is a low-boiling, flammable, and highly volatile gas. Propylene reacts vigorously with oxidizing materials. The primary hazard associated with propylene is its flammability - precautions must be taken to avoid fire hazards in the handling of the gas. Propylene has been mainly produced as ethylene manufacturing co-product (via steam cracking of paraffinic hydrocarbons) and by-product of petroleum refining (separation from refinery gas). Most recently, amid a tight propylene market, novel lower-cost chemical processes for on-purpose propylene production have emerged.
