Maximizing Pump Reliability Through Precision Lubrication
15 March 2016

In most plants, the single largest asset class are pumps. From small ANSI to large API pumps, pump reliability is critical. For this reason, most hydrocarbon processing plants pay particularly close attention to pump reliability and often track Mean Time Between Failure (MTBF). In many plants, pump MTBF varies between 5-8 years depending on the maturity of maintenance practices. But with just a little effort, significant improvements to pump reliability and longevity can be achieved through the application of precision lubrication practices.

Water Wash Design Optimization with Simulation and Empirical Evaluation
15 December 2015

Petro-chemical refiners are required to move crude oil great distances throughout the refining process. Crude oil contains various salts which can lead to corrosion or plugging at various stages in the equipment. Water wash is of-ten implemented to scrub the salts from the process stream to mitigate corrosion risks. Two modes of pipe degradation are addressed in this work: acid corrosion and erosion due to high wall shear stress. The primary focus of this study is to define the parameters with largest impact on the reduction of corrosion and erosion. Distribution of injected water wash and downstream behavior of the excess fluid are the focus of this investigation. This study builds on previous empirical and simulation studies of water wash techniques. A hydraulic spray and multiple quill style injectors were investigated with a nominally uniform cross-flow. These results demonstrate the trajectory change as well as the change in spray plume characteristics over a range of spray types and operating conditions, including counter-current and cross-current operation. The experimental results were acquired with a LaVision Laser Sheet Imaging (LSI) and an Artium Phase Doppler Interferometer (PDI), to measure the spray shape, size, distribution characteristics as well as droplet size and velocity. The spray simulations were conducted using ANSYS FLUENT computational fluid dynamics (CFD) package in conjunction with custom spray injection methods developed in-house. Experimental results are compared with the simulation results to indicate the amount of wash water that can be entrained to interact with the gas stream for corrosion mitigation.

Eliminating Catalyst Cool Down as Critical Path in a Turnaround
15 November 2015

Reducing turnaround duration can dramatically increase refinery profitability. Historically, cooling hydrotreater, hydrocracker, or reformer catalyst has often been on the critical path when maintenance was being performed on those units. This white paper will demonstrate an alternative approach to catalyst cooling that eliminates nitrogen injection and shortens the duration of this task.
