Offshore platform has often produced negative impact on environment by emitting harmful components such as oil droplet, acid gas, toxic materials, etc. For the reason, this study proposes more environment friendly offshore topside process than conventional one, satisfying international environmental standards, minimizing consumption of the utilities, and consequently maximizing an overall profit. For this, we initially developed a mathematical model of topside process that includes three phase separators, gas compressing system, recycle scheme and produced water treatment system. Then, we considered hybrid process configuration including acid gas removal unit and water treatment system by considering its environmental impact. Thirdly, operating condition (e.g. gas to oil ratio, operating pressure, temperature, etc.) was optimized by using stochastic optimization algorithm. Lastly, we conducted economic feasibility study for the design of profitable and eco-friendly offshore platform.
