A corrosion evaluation of mild carbon steel in reclaimed refinery stripped sour water
Journal of Environmental Management, 2020Reclaiming water for cooling systems in oil refineries has been strongly encouraged over the past years for decreasing the large consumption of fresh water, thus contributing to the efficient use of this valuable resource. In a recent study [Journal of Environmental Management 261 (2020) 110229], some of the authors studied the retention of phenols in ...

Petroleum Refinery Stripped Sour Water Treatment Using the Activated Sludge Process
Water Environment Research, 2011A pilot study was performed over 91 days to determine if the activated sludge process could treat a segregated stripped sour water (SSW) stream from a petroleum refinery. The study was performed in two periods. The first period was terminated after 19 days, as a result of excessive sludge bulking.

CORROSION 1981, 1981
Abstract This paper describes the corrosion of equipment by high pH sour water in desulfurizing, MEA gas scrubbing and sour water stripping processes. The sour water is formed by the catalytic conversion of nitrogen and sulfur, present in vacuum gas oil, to ammonia and hydrogen sulfide.

Development of a novel processing system for efficient sour water stripping
Energy, 2017Abstract Application of vapor recompression systems can result in enhanced energy efficiency and reduced energy requirements of distillation systems. In vapor recompression systems, temperature and dew point temperature of the top product of the column are increased through compression.

Simulation and Heat Recovery from Sour Water Stripping Process Using Aspen Hysys
SSRN Electronic Journal, 2021This research article presents a method for extracting heat from sour water process has been developed and depicted through aspen hysys. In the sour water treatment process the feed water is required to be preheated before entering the stripper and the water recovered from the bottom of the stripper possesses high temperature. In this article the water

A deep learning based soft sensor for a sour water stripping plant
2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017In this paper two Soft Sensors, for the estimation of pollutants in the output flow of a Sour Water Stripping plant, are described. The plant operates in a large refinery in Italy. The Soft Sensors have been implemented by non linear data-driven approaches, by using neural networks.

Experimental Investigations of Foaming in a Packed Tower for Sour Water Stripping
Industrial & Engineering Chemistry Research, 2003A foaming problem in an industrial-size deacidifier (packed column) within the ammonia−hydrogen sulfide circulation scrubbing process (AS process) on a specific site is experimentally investigated. The foamability of solutions is successfully assessed in a small test cell, and the Bikermann coefficient is calculated to characterize the foaminess ...

Improvement in steam stripping of sour water through an industrial-scale simulation
Korean Journal of Chemical Engineering, 2004Sour water containing hydrogen sulfide, carbon dioxide, hydrogen cyanide, and ammonia is mainly purified by steam stripping. Increased concern in recent times over effluent water quality and energy saving has caused sour water stripping to attract considerable attention.

Optimization of a Sour Water Stripping Plant Using Surrogate Models
2016Abstract In this work we present a methodology for the large scale optimization of complex chemical processes. In the proposal, processes have been simulated using modular simulators, where units are classified depending on their numerical noise and the CPU time needed to converge.

The modified structure of sour water stripping to improve the pressure control 1
IFAC Proceedings Volumes, 2001Abstract Sour water is mainly purified by steam stripping. In these days, steam stripper has been attracted considerably since effluent water quality and energy saving are getting more important. In this research, several guidelines which can improve stripping performance were proposed.
