This guide represents the chemical resistance of the raw materials used to manufacture products by the Hy-Lok Corporation. In general, media characteristics like temperature fluctuation, concentration, high velocity and abrasion will affect corrosion rating. Before applying this guide, many factors that may affect the compatibility ratings should be considered, and users should test under their own operating conditions to determine which materials can be used.
The Fluid Compatibility Guide provides a rating of compatibility of common metals and elastomers to various chemicals and compounds found in industry. The Hy-Lok Corporation Guide contains data assembled from a variety of sources within the metal and chemical industry. However, due to variations in each user application, we do not make any direct or implied warranty as to any specific use or application based upon the performance of any material in this guide. This guide is for reference only and Hy-Lok Corporation is not responsible for the accuracy of the information therein.

SYNOPSIS
The principles underlying centrifugal separation of particulate species are briefly considered, and the main types of separator available are noted. The procedures available for scale-up from laboratory or semi-technical data are then discussed in detail with particular reference to perhaps the most important class of machine for fine particle processing: the disc-nozzle centrifuge.
Starting with the basic concepts behind their design, discussion follows to explain the factors which may limit centrifuge performance. It is shown how a few simple; laboratory scale tests can give a valuable insight into the design and operation of full-scale industrial machines.

Methanator Water Wash Procedures
To avoid nickel carbonyl formation, it is preferable to heat the catalyst above 400oF in nitrogen or some other CO free gas. If this is impractical and the catalyst must be heated with process gas, low pressure, high rate heating should be employed. The gas must be vented at a height and ideally flared. Care should be taken to ensure all methanator and local drains are shut.

SYNOPSIS
The principles underlying centrifugal separation of particulate species are briefly considered, and the main types of separator available are noted. The procedures available for scale-up from laboratory or semi-technical data are then discussed in detail with particular reference to perhaps the most important class of machine for fine particle processing: the disc-nozzle centrifuge.
Starting with the basic concepts behind their design, discussion follows to explain the factors which may limit centrifuge performance. It is shown how a few simple; laboratory scale tests can give a valuable insight into the design and operation of full-scale industrial machines.

Methanator Water Wash Procedures
To avoid nickel carbonyl formation, it is preferable to heat the catalyst above 400oF in nitrogen or some other CO free gas. If this is impractical and the catalyst must be heated with process gas, low pressure, high rate heating should be employed. The gas must be vented at a height and ideally flared. Care should be taken to ensure all methanator and local drains are shut.

Integration of Rotary Positive Displacement Pumps into a Process
This Engineering Design Guide deals with:
(a) The specification of the pump duty for enquiries to be sent to pump vendors,
(b) The estimation of the characteristics and requirements of the pumps in order to provide preliminary information for design work by others.
It applies to pumps in Group 2 and 3 as defined in GBHE-EDS-MAC-21 Series, and is also an essential preliminary step for a pump in Group 1 whose final duty is negotiated with the chosen pump supplier.
It may be used for general-purpose pumps in Group 4; their duties when used in a support role are often inadequately defined, whereupon such pumps can be specified by reference to the manufacturer's data for a pump satisfactorily fulfilling the same process need.
This Engineering Design Guide has several aims.
It is intended to take an experienced mechanical engineer through the steps necessary to specify a gear and to carry out an assessment of gears offered against a particular specification for pumps, fans and compressors driven by electric motors, steam turbines, combustion gas turbines or expanders. It is not part of this Engineering Design Guide to show how to decide that a gear is or is not necessary for a particular duty.

Overview of the fundamental roles in Hydropower generation and the components involved in wider Electrical Engineering.
This paper presents the design and construction of hydroelectric dams from the hydrologist’s survey of the valley before construction, all aspects and involved disciplines, fluid dynamics, structural engineering, generation and mains frequency regulation to the very transmission of power through the network in the United Kingdom.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Fluid Compatibility Guide
This guide represents the chemical resistance of the raw materials used to manufacture products by the Hy-Lok Corporation.
In general, media characteristics like temperature fluctuation, concentration, high velocity and abrasion will affect corrosion
rating. Before applying this guide, many factors that may affect the compatibility ratings should be considered, and users
should test under their own operating conditions to determine which materials can be used.
Summary of Compatibility
A - Recommended
B - Satisfactory in most cases
C - Potentially unsatisfactory
D - Not recommended
Blank - No information available
Annotation
1 - Satisfactory to 72°F (22°C)
2 - Satisfactory to 120°F (48°C)
The Fluid Compatibility Guide provides a rating of compatibility of common metals and elastomers to various chemicals
and compounds found in industry. The Hy-Lok Corporation Guide contains data assembled from a variety of sources within
the metal and chemical industry. However, due to variations in each user application, we do not make any direct or implied
warranty as to any specific use or application based upon the performance of any material in this guide. This guide is for
reference only and Hy-Lok Corporation is not responsible for the accuracy of the information therein.
