In 2003 the company has passed ISO9001: 2000 quantity system
certification. It is one of the CHINA research and production bases
for molecular sieves and catalysts for more than thirty years. In
1971, 5A strip adsorbent won the National Reward of Invention. The
annual production was 1000 metric tons, the product was used for
kerosene dewaxing units by many refineries in China, and it was
also exported many lots to Romania and Korea.
In 1998 Sinopec NWA adsorbent was put into use in Molex Unit of
Jinling Petrochemical Corporation(SINOPEC) lab Plant.
At present, NWA-IIB 5A adhesive-free spherical adsorbent has been
recognized as the national new key products in 2001. It is
high-tech product with National invention reward and patent gold
metal. The forth replacement of this Plant(of 2 Molex Units) was
carried out in 2005, 160, 000kg NWA-IIB 5A adsorbent was loaded.
Now both of Molex Units are running well.
In 2001, Sinopec NWA-IIB 5A adsorbent was exported to Middle East.
The Molex Unit is running at 118% design capacity with stable
recovery and stable product quality.
In november of 2006, the Molex Unit of another abroad user loaded
with Sinopec NWA-IIB 5A adsorbent was restarted up successfully
with all the technical index up to the expected requirements.
In june of 2007 Sinopec NWA-IIB 5A adsorbent was put in use in
Molex Unit for seven times.
The commercial application shows that the performance of the
adsorbent is in advance of the same kind adsorbents.
Adsorbent OF NWA-IIB is a new spherical adsorbent without binder.
It is of high adsorption-desorption efficiency. It is particularly
suitable for the separation of the normal paraffin and iso-paraffin
in Molex unit. The product was put into use in Molex unit of
Jinling Petrochemical Corporation LAB Plant since 1998.
