Bluestar Petroleum built the largest domestic DCC device

The newly-built 500,000-ton/year catalytic cracking (DCC) unit of China National Bluestar Corporation's Bluestar Petroleum Daqing Branch was recently put into production. This is currently the largest DCC unit in China with a total investment of nearly 700 million yuan.

This set of equipment is designed and built using the patented technology of the Sinopec Research Institute of Petroleum and Petrochemicals, and it ranks in the leading position in the domestic oil refining industry. After the plant is put into operation, the annual output of petrochemical products with a total of nearly 140 tons of 13 brands such as liquefied gas, propylene, gasoline, and diesel can further rationalize the use of existing crude oil resources and maximize the production of refined propylene, isobutylene, and normal butene. With the use of fine chemicals such as liquefied petroleum gas, the industry chain for crude oil processing has been extended to provide conditions for the development of high value-added fine chemicals. It is understood that since the installation of this device was completed at the end of last year, the overall performance has fully met the design requirements.

         At present, the heat metering market commonly used heat table is divided into mechanical heat meter(Mechanical Heat Metering) and ultrasonic heat meter.The mechanical heat meters is consist of temperature sensor, flow sensor and calculator. With the aid of the temperature sensor, The Mechanical Heat Meters measure the inlet water and return water temperature. Flow rate sensor measures the volume rate of the hot water in the tube trough the time difference. The figures recorded will be delivered to integral calculator which calculates the total heat and displays.

 

       The mechanical Heat Meters sensors measures the flow rate through the circles of the wheels. According to the specification, The DN can be â‰¤40mm and ≥50mm. According to the inner structure, the small size mechanical heat meters can be single jet and multi jet. At present, our mechanical heat meters belong to single jet mechanical heat meters and they have higher request from the water quality. According to the counter of the flow sensor, the mechanical heat meters can be dry and wet type. Our mechanical heat meters are the dry type.Except mechanical heat meters,the Plastic Heat Meter is also a good product.
