Decanter centrifuge is widely used in different industries to separate solids from liquid and they are fundamental industrial equipment.

A few days ago a set of decanter centrifuge by GN Solids Control (with tank and flocculant unit) began running in a field site of Sinopec, the second largest oil and gas producer in China.

Mounted on a tank, the decanter centrifuge separates slurry from non-dig project, with the support of dosing unite.

The model of the decanter centrifuge is GNLW553C-VFD, a work horse in the field demonstrated by its outstanding field performance. This model is also widely used in North America.

Many people in North America did not have good opinion toward Chinese products as per their past experience. Their opinion is that Chinese product were cheaper, low quality and low performance. When the first batch of decanter centrifuges by GN Solids Control arrived in the US, they seriously doubt their capability.

In one field test, the project owner bought one decanter centrifuge from GN, and rent another one from a US manufacturer (because the price of decanter centrifuge is almost 3 times that of GN’s decanter centrifuge).

Initial back-to-back test showed that US decanter centrifuge delivered clearer water than that from GN decanter centrifuge. This encourage those gentlemen who were very suspicious about the performance of Chinese products.

The service engineer from GN Solids Control looked at the condition of incoming slurry and the result, analyzed the parameter settings and made some tuning of operation parameters on HMI, magic happened, water turned crystal.

A professional on decanter centrifuge who was on-site during the test recalled that he tried to increase flowrate of the US made decanter centrifuge, discharged water immediately turned turbid, while water from GN decanter centrifuge remained crystal even though he increase feeding flowrate. Up till now he is still unable to figure out why decanter centrifuge from GN Solids Control could perform that way.

GN Solids Control is continue make improvement on its equipment including mechanical design and control package to make it perform better, more reliable and easier to operate.
