In order to meet the demand for clean oil products in the Pearl River Delta, Guangzhou Petrochemical has accelerated the pace of oil quality upgrades. In December 2009, after the 1.5 million-ton/year catalytic gasoline desulfurization unit was put into operation, Guangzhou Petrochemical could produce 220,000 tons of national 4 gasoline per month. The 2 million-ton/year diesel hydrogenation unit upgrades catalyzed diesel, coking diesel, and hydrotreated diesel, so that the diesel blending component meets the national 4 standard, which can meet the demand for clean oil products in Guangzhou.
The machine used is called a squaring shear, power shear, or guillotine. The machine may be foot powered, less commonly hand powered, or mechanically or hydraulically powered. It works by first clamping the material with a ram. A moving blade then comes down across a fixed blade to shear the material.
Metalworking guillotines operate by a clamp securing the sheet of material. Similar to the action of scissors, the blade shears the material, starting at one side of the sheet. ...... In hydraulic guillotines, energy for the tool comes from pressure in a hydraulic ram.
