Abstract As many states in the world strive to reach a state of industrialization, there is a growing need among them to exploit cheaper and effective raw materials for their industries to enhance speedy growth in their economies. Naphtha is a raw material that industrialists need to use to make various industrial products as this study will reveal. The raw material under our study is significantly easy to produce as opposed to various raw materials of its kind and has a multi-purpose value. This study was done to determine how the cracking of naphtha produces olefins. Cracking of naphtha was employed in Texas’ affiliated towns of Houston, Austin and San Antonio. The purpose of the study was to establish the amount of olefin, gasoline and other crude oils that were to be produced in the exercise. The study focused on both specific and general objectives for which the case study was founded. The process of naphtha cracking was considered, the procedure determined, results analyzed and discussed (William, 19). Petroleum products were cracked; naphtha and olefin among other components were collected. Crude oil was heated in a furnace as the primary step in breaking the straight chains. Butane, light naphtha, heavy naphtha, and kerosene were formed. The vacuum tower played a role in producing wet gas. Instrumentation was based on the major units which were the cocker and thermal units. Both properties of naphtha and olefin were considered and discussed in depth. Their advantages and disadvantages in the oil industry were also considered. The uses and application of naphtha and olefin were also analyzed and discussed. Health and environmental considerations were made, and hazards discussed. All possible health outcomes were analyzed and effects like carcinogenesis and dermatitis were put into focus. The methodology involved effective sampling design and procedures, data analysis, presentation and discussion of the results. The sampling design was descriptive in form and the presentation was elaborate and informative especially to the people of Texas. Conclusions were drawn based on the procedure and recommendations. Purpose of the study The study was aimed at investigating the process through which the cracking of naphtha produces olefins. Naphtha, which is a flammable hydrocarbon liquid mixture, holds different properties with most of them being useful, considering the dissimilar industrial components. Naphtha proved to be a central industrial source of crude oil. The purpose of the study was to determine how the cracking of naphtha would produce olefin. The cracking process and industrial application of this vital product were analyzed. The study was meant to create awareness among potential investors in the industrial sector who may find this study useful as it will create a conceptual basis for their energy creation options. Every potential industrialist who realizes the utilitarian value of cracking naphtha to produce olefins may find it necessary to use this study as a guide especially when creating necessary health and environmental guides for his/her workforce and the community at large. Objective of the study General objectives To produce olefin by crackin
