SWCHEM is an engineering company and technology licensor for a wide range of chemical processes. We deliver value and services covering feasibility study reports, technology licensing, engineering design and EPC delivery for various chemical applications.
By combining process expertise, engineering capability and industrial experience, SWCHEM provides integrated, cost-effective and environmental commitment solutions for customers worldwide.
In response to market needs, SWCHEM is also open to technical consultation, joint development and cross-sector cooperation with companies, universities, research institutes and technology partners around the world.
Dimethyl ether, DME, is an important raw material used in a wide range of industrial applications. SWCHEM's methanol-to-DME synthesis technology enables customers to produce aerosol-grade, fuel-grade and other grades of DME in a cost-effective and reliable way.
Licensed by SWCHEM and supported by our proprietary reforming catalysts, more than 30 hydrocarbon-to-H₂ plants have been put into long-term stable operation.
SWCHEM's reforming catalysts have been widely applied in China's reforming processes and hold a strong market position in the domestic industry.
H₂ production from methanol involves fewer process steps than conventional H₂ production routes, which can lead to lower investment costs and improved operational reliability.
Although the unit H₂ production cost may be slightly higher than that of traditional natural gas reforming, methanol reforming is widely accepted by medium-scale H₂ consumers due to its compact process, flexible operation and reliable performance.
Coke oven gas, COG, is a by-product of coke production. Due to its complex composition and impurity content, it is often used only as low-value fuel gas.
With SWCHEM's COG treatment and methanol synthesis technologies, low-value coke oven gas can be upgraded into methanol, creating higher economic value while improving resource utilization.
SWCHEM provides integrated methanol synthesis technologies supported by proprietary catalysts for the overall methanol production process.
With the close integration of process technology, catalyst performance and engineering experience, methanol plants contracted by SWCHEM have been well recognized by the market for their reliability and long-term operating performance.
SWCHEM's natural gas-to-methanol technology enables customers to produce methanol in a cost-effective and reliable manner.
SWCHEM is one of the original developers of methanol-based acetic acid synthesis technology. Our proprietary acetic acid synthesis technology has been licensed to leading international customers, including Celanese.
In regions where natural gas supply is limited or costly, synthetic natural gas can provide an attractive alternative for civil and industrial applications.
SWCHEM provides reliable technology licensing, engineering services and complete catalyst solutions for COG-to-SNG projects. With around 30 references built and put into operation by SWCHEM, this technology has proven its ability to convert coke oven gas into a higher-value clean gas product.
With decades of dedication to chemical technologies and industrial applications, SWCHEM is ready to work with customers worldwide to address technical challenges and create long-term value.
