The high-pressure polyethylene process uses cyclone separators to separate ethylene gas, polyethylene, and its oligomers. oligomers larger than 10 microns that cannot be separated must filtered through a filter prevent them from entering the compressor affecting normal operation. When separation efficiency of separator is low, cleaned more frequently, which will reduce production efficiency. Re...

Study was carried out to assess the impact of cement dust on some selected plant species around industrial area. Deposition effect of cement dust on pigmentation was studied in Azadirachta indica, Pongamia pinnata, Delonix regia, Polyalthia longifolia and Ficus religiosa. Sampling was done about 500 meter distance difference from the cement industry and measurements were taken for all the plant...

In this study it has been initiated to find out the credit strength and financial performance of cement industries in Bangladesh through investigating the financial report for the period from 2007 to 2011. Financial ratios are employed to measure the Liquidity (Working capital to Total Assets), Profitability (Retained Earnings to Total Assets), Efficiency (Earnings before Interest and Taxes to ...

The main process system is reported. typical problems during period are analyzed, including blockage primary cyclone separator, loop seal, inventory leakage blast cap on air distribution plate, feeding tube coking, and large fluctuation pressure. Reasonable improvement c...

Abstract This paper described the plant scale catalytic process of plastic waste materials in order to obtain an alternative fuel from three wastes Polypropylene (PP), Polystyrene (PS) and Polyethylene (PE). Pyrolysis is thermochemical decomposition plastics at elevated temperatures (in absence or little supply oxygen) into a range useful products: gas, liquid, solid residue. These have consist...
