We are the trailblazer in China's coal chemical engineering sector. Coal chemical, natural gas chemical, C1 chemical engineering are our crown jewels. Over the years, we have earned a solid track record in the coal chemical engineering sector enabled by our state-of-the-art technologies and vast experiences. Breakthroughs are made in the project size, capacity and geological location with our leading technologies developed and upgraded as a result of learning, integration and scale-up. Over the last decade, we have been expanding our service scope to EPC, and have been making drastic progress in plant capacity and application of in-house technologies.

Flagship Projects：
1.7 MMTPA coal-based methanol-to-olefins (MTO) project, Zhong An United Coal Chemical Co., Ltd.

The project is a joint venture between Sinopec and Anhui's Wanbei Coal-Electricity Group. SNEI delivered as EPC contractor the syngas plant with a capacity of 505,563 Nm3/h (as CO+H2), and the methanol plant with a capacity of 1.8 MMTPA (as 100% methanol).

Syngas debottleneck and acetic acid revamp and upgrade project, Sinopec Great Wall Energy & Chemical (Ningxia) Co., Ltd.

This is China's first big coal chemical upgrade and revamp project, with a capacity expansion by 40%. The coal slurry concentration is increased to 64.1%, and the effective gas volume is up to 216,854.2 Nm3/h. SNEI delivered this EPC project based on a revamp solution developed in-house.

100,000 Nm3/h coal-based hydrogen production unit, Sinopec Jiujiang Company

SNEI delivered this EPC project based on Sinopec's low-temperature methanol wash semi-lean solution circulation technology and coal slurry gasification at 4.0MPa. SNEI earned the National Quality Project Award, Sinopec Quality Project Award, and the second prize of the National Excellent Project Engineering Award.

90 KTPA coal-based hydrogen production unit and associated air separation unit (ASU), Sinopec Nanjing Chemical Industrial Corporation

This project is based on a licensed coal slurry gasification technology, with a hydrogen production capacity of 126,000 Nm3/h, Ф3200 gasifiers (2 running and 1 standby), coal feed of 1,000t/d per gasifier; with an associated ASU of 56,000 Nm3/h.
