In many explored gas reservoirs in the word, which are considered as gas-gas condensate reservoirs, many surface facilities receive the gas as well as hydrocarbon condensates and water. Condensates cause slugs in a pipeline. The slugs, which are an aggregate of fluids, cause many problems in multiphase pipelines. Therefore, in order to separate condensates, slug catchers are normally used. A slug catcher is necessary equipment at the entry of a multi-phase flow processing factory. The specific performance of a slug catcher is the separation of gas and liquid phases and temporary storage of the liquids. In this paper, we recommend a method for designing finger type slug catchers, based on two phase flow in principles. Then, using the proposed method, we design a slug catcher for the two present phases in the South Pars gas field. At the end, by considering condensate recovery and economical investigation of the suggested slug catchers, we choose the optimum slug catcher for these two phases. Among the most important results of this investigation, we can mention an efficient pattern for designing finger type slug catchers and the selection of the optimum one. Using this pattern is recommended for a proper design and reduction of time and costs.
