51317--9514-Work Life Balance – Revisiting the Relationship Between Desalting Efficiency and Overhead Corrosion

Product Number: 51317--9514-SG
ISBN: 9514 2017 CP
Author: James Noland
Publication Date: 2017
$20.00

It has been documented that improved desalting efficiency reduces the risk of corrosion and vice versa. This paper introduces a new way of using the desalting process to help control overhead corrosion. The end result is the corrosion engineer has a new tool to reduce the risk of salt formation.

Instrument air (IA) system is one of the critical systems in the utilities section of a refinery complex. IA system of this refinery consists of compressor package and dryer package to supply air to refinery header at 0.9Mpa (128 psi) with dew point less than -20degC (-4degF). The 3 stage compressors have intercoolers with extended plate surface fin type tubes. The metallurgy of the tubes is Admiralty brass SB-111 C44300. In this cooler, compressed air is in the shell side and fresh cooling water on the tube side. All 8 intercoolers in the compressor package leaked in a period of 1 month. A failed sample tube was analyzed using Optical Emission Spectroscopy, Stereo Microscope, SEM/EDS and XRD. This paper discusses the findings and the methodology used to identify the reason for failure as Ammonia Stress Corrosion Cracking. Process parameter analysis revealed that the leak from a recycle gas cooler in Hydrocracker unit as the possible source for ammonia in cooling water system. The full-length tube expansion for plate type fins is the source for residual stress. This paper briefs upon the IOW and the monitoring mechanisms for such mixed metallurgy closed loop cooling water system.

VOC was one of the paint emissions accused to be an environmental hazardous material and among the main causes for SBS (Sick Building Syndrome). The term SBS was coined in the late 1970's to describe situations where building occupants experienced acute health problems. “According to WHO (World Health Organization), 4.3 million people a year die from the exposure to in-house air pollution”

This twin train Condensate Splitting Unit (CSU) is basically an atmospheric distillation unit processing predominantly Middle Eastern condensate along with other non-system condensate. The products from this unit are Light/Heavy Naphtha, Kerosene, Light/Heavy Gas Oil and Atmospheric residue. There is no desalter in this unit and preheated feed is flashed in Pre-flash column to separate out light and medium naphtha.
