Polyether polyol project

Polyether polyol project

1.Product introduction

Polyether polyols (referred to as polyethers) are prepared by addition polymerization of an initiator (a compound containing an active hydrogen group) with ethylene oxide (EO) and propylene oxide (PO) in the presence of a catalyst。Polymers whose main chains contain ether bonds (-R-O-R -) and whose end groups or side groups contain more than 2 hydroxyl groups (-OH) are collectively referred to as polyether polyols。At room temperature, it is a colorless to brown viscous liquid, usually soluble in aromatic hydrocarbons, halogenated hydrocarbons, alcohols, ketones, and hygroscopic。Under the action of catalyst, polyhydroxyl or polyamine compounds were used as starting agents to synthesize with oxidized olefin by ring-opening homopolymerization or copolymerization。For example, glycerol reacts with propylene oxide and ethylene oxide to obtain polyether triol with molecular weight of 3000 ~ 5000。The largest yield of polyether is glycerol (glycerol) as the starting agent and epoxide (generally PO and EO combined), by changing the way of PO and EO feeding (mixed or separate adding), adding ratio, adding order and other conditions, to produce a variety of general polyether polyols。

2.Market prospect analysis

China's polyether polyol production demand has accelerated significantly after 2014, with an average annual growth of 18% in 2014 and an average annual growth of 12% in output.At 5%, demand is growing at an average annual rate of 15%.9%。Although the production capacity growth is very fast, but the effective production capacity will not be too high, the operating rate is only about 70%, in the end of 2014 to 2015 to reach the balance of supply and demand, but China's capacity structure and technical strength limitations, China's hard bubble and special polyether continue to need imports to supplement。

At present, there are more than 30 polyether polyol production enterprises in China, and the production capacity has reached 2.56 million tons in 2014, and the total output has reached 1.8 million tons, of which nearly 20 are above the 10,000-ton scale。With the promotion of the national "13th Five-Year Plan" energy conservation and emission reduction goals, the energy efficiency standards for two terminal energy products of refrigeration freezers and household solar hot water systems have been introduced, and the innovation of wall insulation materials is also constantly improving, and a series of favorable policies have brought new development opportunities to the polyurethane industry。Polyether polyols, as one of the important raw materials for polyurethane production, also ushered in the development opportunity。 At present, 80% of polyether polyols in China are used in the field of polyurethane, mainly for the production of polyurethane soft bubbles, polyurethane hard bubbles and the production of CASE systems。From the perspective of market share, polyurethane soft foam accounts for about 70%, hard foam is about 25%, and CASE class is less than 5%。 From the perspective of downstream consumption structure, polyurethane soft foam is mainly used in the field of furniture and car cushions, hard foam is mainly used in cold storage and insulation, construction industry and solar water heater, CASE system mainly refers to the application in the fields of coatings, adhesives, sealants and elastomers。In the past two years, with the continuous improvement of national energy conservation and emission reduction and the continuous improvement of green environmental protection, the demand for hard bubble polyether in the construction field and soft bubble polyether in the automotive field is expected to maintain a strong development momentum。However, on the whole, China's soft foam polyether overcapacity, relatively saturated, the future growth rate should be lower than hard foam polyether。 At present, the consumption of hard foam polyether in China is still concentrated in the refrigeration industry, accounting for about 58% of the total consumption of hard foam, and the construction industry is only about 22%。

3.Construction scale and product scheme

Construction scale and product scheme: The construction scale of the project is 100,000 tons/year polyether polyol。Due to the polyether varieties and grades, the specific product varieties and grades are determined according to market conditions before construction。

The project covers an area of about 50 mu。

4.Technical and equipment solutions

This project adopts batch production method。The main equipment of the project includes reactor, neutralization kettle, DCS control system, water treatment equipment, air compressor, vacuum pump, etc。The reactor volume is 80m3, which is the largest in China。

5.Expected economic benefit analysis

The total investment of this project is about 80 million yuan, estimated according to the peak market price of raw materials and products, after the completion of this project, the unit cost of polyether polyol is 13,900 yuan/ton, and the annual total cost is 1.39 million yuan。

Annual sales revenue: 1,524 million yuan, annual profit and tax: 134 million yuan。
