The separation of produced fluids is essential once it reaches the surface. This separation is achieved in gravity separators. The design and sizing of separators can be challenging due to the number of factors involved. Improper separator design can bottleneck and reduce the production of the entire facility. This paper describes the development of a capital cost optimisation model for sizing three phase separators. The developed model uses GRG Non-linear algorithms to determine the minimum cost associated with the construction of horizontal separators subject to four sets of constraints. A numerical sizing example was solved to provide the details associated with the model and the ease with which parameters can be varied to suit the user's needs. Finally, a spreadsheet comparison between results obtained from the developed model and four other extant models is carried out. Results indicated that the developed model predicted results within an absolute error of AE5m 3 in most cases and a maximum of AE12.5m 3 for very high gas flows in comparison to conventional models developed based on retention time theory.

Petroleum refinery effluents such as phenol are very toxic and impose a serious ecological issues. The employment of UV/ZnO NRs system for the degradation of phenol in aqueous solution has been investigated in the present study. The ZnO NRs were synthesized by hydrothermal growth method and characterized spectroscopically exploiting SEM and UV-VIS. It was noticed that the degradation of phenol depends on several operational parameters such as the initial concentration (5ppm, 10 ppm or 20 ppm), the irradiation time (between 0 and 10 hours), and the UV light energy (365 nm or 254 nm). The photocatalytic degradation rates of phenol was observed to follow the pseudo first order kinetics according to the Langmuir-Hinshelwood model. An efficient degradation of about 90 % was registered under 254 nm for an irradiation time of 10 hours.

“…Desenvolvimentos recentes no processo de oxidação da amônia visam minimizar as perdas do catalisador (RAY; JOHNSTON, 1989). Melhorias na filtração possibilitam maximizar o rendimento, minimizando os custos de operação e assegurando um serviço sem problemas, (BAUR, PETHICK, 1991), pela instalação de filtros de recuperação de platina em vários estágios do processo.…”
