Hubei Xinyi Chemical Co., Ltd. 550 KTA Ethanol Amine Project

Overview

This project implemented coal-water slurry gasification technology and upgraded the liquid ammonia and methanol production units, boasting an annual production capacity of 460 kt liquid ammonia, 90 kt methanol, and 21.3 kt sulfuric acid (by-product).

Solutions

HollySys provided a comprehensive suite of solutions for this project, including Distributed Control System (DCS), Asset Management System (AMS), Safety Instrumented System (SIS), Gas Detection System (GDS), Simulation & Operator Training System (OTS), Operational Data System (ODS), Advanced Alarm System (AAS), as well as hardware and software related to information security, along with matching auxiliary instrument equipment. Our integrated plant-wide solution enhanced automation and environmental sustainability, promoting energy efficiency.

Results

Through our solution, the project achieved higher levels of automation and environmental sustainability, leading to improved energy efficiency. Compared to traditional units, coal consumption per ton of ammonia raw material decreased by 180 kg, and the cost of liquid ammonia decreased by about 1008 yuan per ton, saving 110 kt standard coal annually.
