New 300,000 tons/year styrene project
Thread Content
I would like to ask the experienced colleagues: how many mu of land is required to build a new styrene plant with an annual production capacity of 300,000 tons? What is the approximate investment cost? And how many employees will be needed?
It depends on whether it is an expansion project for an existing factory or a new construction project; the utility infrastructure used varies, and there are differences in land usage, workforce requirements, and investment. For the 600,000 tons/year ethylbenzene and 300,000 tons/year styrene projects, the total investment in the facilities themselves is approximately 800-1,000 million yuan.
A new project will be established using the ethylene process to produce only styrene, with utility services to be sourced as much as possible from the chemical industrial park
What is the process for producing styrene via the ethylene method? Studying*. Currently, the main methods for producing styrene worldwide include ethylbenzene dehydrogenation, propylene oxide-styrene co-production, extraction and distillation of pyrolytic gasoline, and butadiene synthesis. In recent years, the styrene plants built in China have basically adopted the ethylbenzene dehydrogenation process.
Ugh, did the design institute not do a good job for you?
I saw on the internet that if ethylene is purchased externally, considering the construction of an ethylene cryogenic tank would result in significant additional investment. It might be a misstatement. I truly hope to get your advice: roughly how many mu of land is needed to simply establish a new styrene production project? How much to invest? What is the capacity? Ethylene and pure benzene are purchased externally, while utility services are sought to be sourced from the chemical industrial park whenever possible.
I haven’t contacted any design firms yet; I just need an overview as a potential option for future projects.
As mentioned regarding investment, an investment of 300,000 tons would amount to around 800-1 billion； Land area: For your reference, a project with an EB/SM capacity of 500,000 tons requires approximately 66 hectares of land ； Capacity: Approximately between 200 and 250 people.
Raw material and product tanks are required, as well as units for ethylbenzene and styrene, or a co-production method. The plant area needs to be around 100 mu; the tank area can be 30 mu depending on the requirements. The workforce consists of 110 people working in five shifts with three rotations each, including managers, technicians, and operators. For now, 1 billion
