This chapter describes Acetylene production by partial oxidation of methane. This process was chosen and will be discussed next. 2.1 Introduction The process of acetylene production by partial oxidation of methane, involves feeding, preheating, burner, quenching and finally the purifying section. The method of converting methane to acetylene by preheating the mixture of oxygen and methane, this mixture react to form a product gas containing acetylene, ethylene , carbon dioxide and hydrocarbons. The reacted mixture is rapidly expanded and cooled. The feed mixture contains a mole ratio of methane to oxygen ranging from about 0.75:1 to 1.65:1. [1] Figure (2.1) below shows the Block Flow Diagram (BFD) for the process. Figure (2.1) Block flow diagram for the partial oxidation of methane to acetylene. 2.2 Feeding section The feedstock for partial oxidation process is methane which can be supplied from different sources including natural gas and biomass. Methane from natural gas is an important industrial raw material for the production of acetylene, synthesis gas and methanol. Natural gas is a non-renewable source; moreover the production of methane from biomass represents an attractive sustainable option. The current trend is to convert industries based on non-renewable resources to others based on renewable resources. Industrial processes that use biomass as raw materials are an important option in mitigating the effects of global warming. The new industrial processes that use biomass as raw materials show how these processes could be integrated into existing chemical production complexes. Sustainable chemical processes based on renewable resources require the availability of raw materials for biobased feedstocks. Demand for products from these feedstocks and available capacities of plants that produce these
