Clariant has announced the start-up of its MegaMax 800 methanol synthesis catalyst at China National Offshore Oil Corp.’s (CNOOC) China BlueChemical methanol plant in Hainan province, China.
CNOOC’s China BlueChemical subsidiary is a large-scale operation unit specialised in methanol-based chemical products and mineral fertilizers such as urea, phosphates and compound fertilizers. The Hainan site’s ‘Phase 2’ methanol production plant, which has been operating since 2010, has an annual capacity of 800 000 t, and runs on DAVY™ methanol process technology. The MegaMax 800 was recently installed at the facility and commissioned on 28 June 2018.
Key performance indicators were improved with the new catalyst compared to the facility’s previous catalyst start-up. Within the first 24 hours, the plant produced around 25 t (1%) more methanol at 2% less make-up gas feed than in earlier performance runs.
The increase in yield is largely due to the catalyst’s temperature distribution within the catalyst beds, as demonstrated by lower inlet and hotspot temperatures. The steam drum can be operated at lower pressure while providing higher conversion per catalyst volume. Other improvements include lower operating loop pressure and slightly higher steam production.
Clariant’s ReforMax® 210 LDP and ReforMax 330 LDP catalysts are also used in the plant and in the ‘Phase 1’ methanol facility.
