Abstract
Petrochemical industry (PC) is one of the largest and greatest industries in the world. Petrochemical industry consists of different inter-related subsectors producing a variety of products. Each subsector many be viewed as a separate industry, although the output of each stage of production is the major raw material input for the next stage of production. The main product of the Egyptian petrochemical company(EPC) is polyvinylchloride (PVC) which is a synthetic polymer material , which is built up by the repetitive addition of the monomer viny1 chloride(VCM) with the formula CH2=CHCL. PVC has thus the same structure as polyethylene except for the presence of chlorine. The chlorine in PVC represents 57% of the weight of the pure polymer resin
Egyptian Petrochemical Company (EPC) is located in Amerya, Alexandria and occupies about 600 acres (Feddans), is the sole producer of polyviny1 chloride (PVC) resins in Egypt. It produces PVC resins, caustic soda, sodium hypochlorite, chlorine liquid , and hydrochloric acid, and is discharging its wastes into El-Tahrir drain, the control of the quality of the wastes discharged into the Nubaria canal is needed to protect this important source from pollution
The waste generated from the company causes serious problem in the streams receiving such wastes. The major problem is the generation of liquid chlorinated hydrocarbons during processes in addition to the amounts that are discharged during the frequent shut-down of the viny1 chloride monomer (VCM) unit. The second problem is the filter cake from primary brine treatment section in chlorine plant containing water-insoluble material such as calcium and magnesium carbonate and sulfate, is removed by trucks to area within EPC fences. Presently, the filter press is out of service most of the time and when operated it does not efficiently function and part of the slurry escapes to the waste steam. This material could cause many severe environmental and public health problems
