Introduction Condensate is the liquid formed by the condensation of a gas,specifically, the hydrocarbon liquid separate from natural gasbecause of changes in temperature and pressure when thegas from the reservoir was delivered to the surfaceseparators. Such condensate remains a liquid at atmospherictemperature and pressure. Condensate stabilization is the removal of light componentsfrom hydrocarbon liquid to lower its vapour pressure to adesired level. Stabilization may be used to meet a requiredpipeline sales contract specification or to minimize thevaporization of the hydrocarbon.3

Objectives Based on actual plant data in the literature, it carried out asimulation using Aspen HYSYS software to predict theopposite process behavior on some proposed amendments(Rahmanian, Ilias and Nasrifar, 2015). In the static software module, changes in temperature,pressure and flow of plant behavior were evaluated. In the dynamic software module, a control system was testedand configured to stabilize disturbances in the model.6
Methodology In this work we use the software Aspen Hysys version 8.6 Fluid-package: Peng-Robinson Feed condition7

Conclusions The simulation performed for the condensate stabilization providedspecification of the products like the RVP criteria, were presented inthis work similarly to all changes programmed into the system. The changes in the feed stream (temperature, pressure and flow)influenced product quality. It is necessary to set other process specifications to simulate theconditions of condensate stabilization. It was possible to develop dynamic models for the process withadded columns for regeneration of MEG and for separating the finalproduct. The adjustment of the controllers is essential to the stabilization ofthe dynamic models.14

as crude oil. In the case of raw condensate, there are no particular specifications for the product other than the process requirements. The process of increasing the amount of intermediates (C3 to C5) and heavy (C 6) components in the condensate is called “condensate stabilization”. The purpose of this work aims to investigate Reid Vapor
the Khangiran condensation stabilization unit whereas the second from Natural Gas Liquid (NGL) 3100 condensate stabilization unit, both in Iran. In their studies, heat duties and capital costs of units represent the units' performances. RVP of the feed had a great effect on the stabilization units' performances.

It is a condensate collection point for the steam generator. From the condenser, the condensate flows into the condensate pump and then through the other components in the condensate system. In order to protect pumps from overheating and to prevent cavitation, Fisher condensate pump recirculation valves withstand varying
of steam is removed, the condensate will be close to the saturation temperature corresponding to the steam pressure in the heat exchanger shell. Slight sub-cooling of the condensate will occur before exiting from the shell. A steam trap is installed in the condensate outlet piping. The traps function is to drain condensate but to prevent live
The condensate typically has particulate contaminant presentas well. The effects of these contaminants can be severe and costly to the condensate stabilization plant and the export pipeline. Problems that have been encountered include off-spec condensate and final products, poor plant reliability, compromised plant performance and
Abrasive Jet machining can be employed for machining super alloys and refractory from materials. This process is based on surface erosion process. The process parameters that control metal removal rate are air quality and pressure, Abrasive grain size, nozzle material, nozzle diameter, stand of distance between nozzle tip and work surface.
