The document provides a 10-step process for effectively designing storage bins for powders and bulk solids based on their flow properties and process requirements. The key steps include: 1) defining storage requirements, 2) understanding potential flow problems, 3) measuring the material's flow properties, 4) calculating approximate bin size, 5) determining whether funnel flow or mass flow is needed based on the material's characteristics and process needs, and 6) designing the bin to achieve the target flow pattern. The goal is to design bins that reliably discharge materials without issues like arching, ratholing, or segregation.
Determining the Sand Content in Various Compositions of Drilling MudIRJESJOURNAL
Abstract :- Drilling is an important part of the oil industry and penetration rate must be enhanced to ensure speedy completion of drilling operation. Weight on bit, Rotary speed, drill bit type, formation characteristics and mud properties are the basic factors that affect the penetration rate of a bit. Regular determination of the sand content of drilling mud is necessary because these particles can be highly abrasive, and can cause excessive wear of pump parts, drill bits, and pipe connections, excessive sand may also result in the deposition of a thick filter cake on the walls of the hole, or it may settle in the hole around the tools when circulation is temporarily halted, interfering with the operation of drilling tools of settling casing. The sand content test for set is used in the test for sand content determination using Bariod sand content set.

it is a benficial slide who wants to know about the drilling fluids and the rhelogical aspects of the drilling fluids. the things are clear and very clear in this slide and this slide is very beneficial for the one who know basics of drilling fluids in a knowledgeable way
Uncontrolled water ingress, especially water from a pavement’s surface, contributes to multiple types of pavement distress. It can lead to spalling, base or subgrade softening, dowel bar corrosion, pavement joint blow-ups and/or materials-related distress.
The fifth presentation of a series of presentations on Operations Geology. Very basic, just to introduce beginners to operations geology. I hope the end users will find this and the following presentations very helpful.

Introduction:
Gas Absorption is one of the very first Mass Transfer Unit Operations studied in early process engineering. It is very important in several Separation Processes, as it is used extensively in the Chemical industry.
Understanding the concept behind Gas-Gas and Gas-Liquid mass transfer interaction will allow you to understand and model Absorbers, Strippers, Scrubbers, Washers, Bubblers, etc…
We will cover:
- REVIEW: Of Mass Transfer Basics required
- GAS-LIQUID interaction in the molecular level, the two-film theory
- ABSORPTION Theory
- Application of Absorption in the Industry
- Counter-current & Co-current Operation
- Several equipment to carry Gas-Liquid Operations
- Bubble, Spray, Packed and Tray Column equipments
- Solvent Selection
- Design & Operation of Packed Towers
- Pressure drop due to packings
- Solvent Selection
- Design & Operation of Tray Columns
- Single Component Absorption
- Single Component Stripping/Desorption
- Diluted and Concentrated Absorption
- Basics: Multicomponent Absorption
- Software Simulation for Absorption/Stripping Operations (ASPEN PLUS/HYSYS)

The Difference between Silos and Hoppers -- and How to Improve Material FlowControl Concepts USA
Silos and hoppers are prone to different material flow issues. Learn the difference between the two and how material flow can help improve their performance.
The material handling of the feedstock is a very critical part of the extrusion process. If the feedstock is not introduced to the feedsection of screw in a smooth and uniform matter, then the likelihood of a stable and consistent output is unlikely. This is the reason why it is very important that if regrind is added to the virgin feedstock, it must be done very consistently and uniformly. It should also be mentioned here that a very important part of the extrusion equipment is the hopper and feedthroat section. If the hopper and feedthroat sections are not designed properly, inconsistent material flow to the screw can take place. For example, if the conical section of the hopper (see figure) does not have the proper transition, the resin will not flow smoothly into the feedthroat of the extruder.
Like all civil engineering projects, landfill construction projects have fundamental requirements
related to strength, safety and economic concerns. There are precautions that must be taken in the planning
period of a sanitary landfill project, at every step of the construction and after the completion of waste
deposition at the site. The objective is to provide long term stability, environmental protection, ensure
regulatory compliance and achieve cost effective utilization of manpower, equipment and space. This paper
discusses the criteria for site selection, possible soil problems and their effects on safety and necessary
precautions. Studies have shown that the major possible soil deformation modes are landfall, overturn, sliding,
lateral deformation and outflow.
molecular distillation and packed columm distillationkuldeepp4652
Theory of molecular distillation:-
The mean free path of a molecule is defined as the average distance through which a molecule can move without coming into collision with another. For material that are regarded as non volatile under ordinary conditions of temperature and pressure are generally removed by this by increasing the mean free path.
Characteristics of the molecular distillation process:-
Very high vacuum
Evaporating surface must be close to the condensing surface
The liquid area is large to avoid boiling and evolution of the vapors is from surface only.
Packed distillation columns
Packed columns are used for distillation, gas absorption and liquid-liquid extraction.
The gas-liquid contact in a packed column is continuous, not stage-wise, as in a plate column.The liquid flows down in the column over a packing surface and the vapor (or the gas) movescounter-currently, up the column. The performance of a packed column is very dependent onthe maintenance of good liquid and gas distribution through the packed bed, and this is animportant consideration in packed column design
