The heavy oil hydrogenation unit of 2.6 million tons/year and oil product quality upgrade project of 8000Nm³/h PSA hydrogen unit for Lijin Petrochemical Plant Co., Ltd. was successfully put into operation at first attempt on January 9, 2016 and able to produce qualified hydrogen.

The unit used the mixture of dehydrogenation exhaust, coal-to-hydrogen PSA gas and low-molecular purification gas as raw material. Such mixture is featured by complex components, high content of heavy hydrocarbon, and difficult in separation. In order to overcome this technical difficulty, the unit used the PSA technology and special adsorbent which were independently developed by Shanghai Huaxi Chemical Industry Science & Technology Co., Ltd. (“HCIST”). Its core component of PAS — programmable valve was also provided by HCIST to ensure the successful operation of the unit.

After 72-hour continuous operation, the control functions and technical indicators of the unit all met design requirements and production requirements. The unit was officially delivered to Lijin Petrochemical Plant Co., Ltd. on January 12, 2016.
