Experimental and Theoretical Assessment of Fuel Production from Waste Plastics

Abstract Recently more than 150 million tonnes of plastics were produced in the world. On the one hand, the consumption and production of polymers are increasing, on the other hand as landfill and incineration become more expensive and less accepted .The increasing amount of polymer wastes from them generates further mainly environmental problems. The recycling of plastic wastes is gaining increasing importance. Pyrolysis is one promising method for the treatment of mixed and contaminated plastic wastes. In this way the plastic wastes are converted into fuels or other valuable feedstock for the petrochemical industry. In present work catalytic cracking of waste plastics blend with HGO [Libyan gas oil supplied by the Zawia Oil Refinery Company boils in the range of 275-375Cº] was investigated using H-ZSM5and H-BETA. Reaction systems that were studied included high density polyethylene HDPE and polypropylene blend with HGO, reactions were carried out in one litre micro autoclave reactor under different conditions of weight, temperature and type of catalyst, The optimum conditions were 2.5% catalyst by weight of total feed stock, one hour, atmospheric presser and three temperatures selected 400Cº, 425Cº and 450Cº. The product distribution for the system [plastics and HGO] provided some good results high yield of liquid [gasoline] up to 210Cº, gases and small amount of heavy oils. Some analysis was used to qualify and quantify the product. The results from GC.MS analysis showed that the yield of gasoline (c5-c12) over H-ZSM5 higher than H-BETA. In case of 5%PP, 15%HDPE and 80%HGO over H-ZSM5 at 450Cº, 96% total conversion achieved. The result from TGA in the same case is 15% by weight. Also the theoretical calculations to quantify the produced gases after burring of waste plastic in rotary kiln reactor have been evaluated. it is found that the suitable ratio of CO:H2 to produce methanol is 7:1

Assessment Study of Energy Consumption in Ras Lanuf Refinery by pinch Analysis

Abstract Against the background due to the energy crisis in the late 1970’s, the pinch analysis has emerged as a powerful tool for the integrated design of process heat networks which include heat exchangers, distillation columns, furnaces, etc..The key strategy of this methodology is to set energy targets prior to design based on basic thermodynamic principles.The subject of this thesis in to apply this analysis to one of the Libyan Refineries, namely Ras Lanuf Refinery, to assess energy utilization of such big energy – consuming plants and to explore the potential of energy as well as capital costs savings based on the finding of applying this analysis. Based on actual operating data collected from the plant and application of the procedure of the pinch analysis to this real case study where a minimum temperature difference approach in the Ras Lanuf refinery heat exchangers design of 10 (ΔT min =10 ) the following results were obtained. Actual rate of energy consumption of the base case design of the refinery is 9MW which is provided by burning fuel oil in the furnace, while the minimum target predicted by the pinch analysis should be 8MW. This amounts to just over 11% energy savings which equivalent to $462,000 per year reduction in the operating cost of the refinery

MODELING OF HEAT TRANSFER IN BURNING ZONE OF ROTARY CEMENT KILN

Rotary Kilns are one of the most widely used pieces of processing equipment. They are used for drying or calcinng a variety of products including sand, aggregates, limestone and food products. Heat transfer in rotary kilns encompasses all the modes of transport mechanisms, that is conduction, convection and radiation. In rotary kiln operations the chemical reactions in the bed required high temperatures. The energy to raise the temperature and drive endothermic reactions is from the combustion of a range fuels such as heavy oil, natural gas, coal and more alternative fuels. Heat transfer from the gas to the bed is complex and occurs from the gas to the bed surface and kiln wall to bed surface via conduction, convection and radiation. The study concerned to perform a mathematical modeling to simulate of the heat transport in the cement rotary kiln to predict the temperatures at internal and external wall surfaces of the rotary kiln to preventing many industrial problems through the operation process such as (loss of coating, red spots formation, ….) also to predict the optimum range conditions for safe operation. The results obtained show that, the predicted data using a mathematical model satisfied with industrial data for burning zone. The study showed a derived mathematical model can be used with a good reliability to description of heat transfer in burning zone of rotary cement kilns.
