Dynamic Simulation in Chemical Engineering

Dynamic-Simulation-in-Chemical-Engineering

Dynamic simulation is an extension of steady-state process simulation whereby time-dependence is built into the models via derivative terms i.e. accumulation of mass and energy. The advent of dynamic simulation means that the time-dependent description and control of real processes in real or simulated time are possible. This includes the description of starting up and shutting down a plant, changes ... Read More »

ASTM / American Society for Testing and Materials

ASTM-American-Society-for-Testing-and-Materials

There are numerous American Society for Testing and Materials designations cover the specification of wrought materials, forgings and castings used for plate, fittings, pipe and valves.The ASTM standards are directed to dimensional standards, materials and strength considerations. Some of the more material standards referenced are: A 36 Specification for Structural Steel A 53 Specification for Pipe, Steel, Black and Hot ... Read More »

EFW Pipe vs ERW Pipe

EFW-Pipe-vs-ERW-Pipe

EFW Pipe vs ERW Pipe:- EFW Pipe Manufacturing Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. To form a continuous ribbon of steel several coils are welded together. Then the steel ribbon is heated to the necessary temperature and formed into an oval. In the next step ... Read More »

What is Oil Refinery ?

what-is-oil-refinery

When talking about refinery, we need to be able to differentiate and identify an oil refinery from the edible oil refinery. Basically, the oil refinery (or petroleum refinery) is an industrial process plant where crude oil (from crude petroleum) is processed and refined into more useful petroleum products, such as Gasoline Diesel fuel Asphalt base Heating oil Kerosene Liquefied petroleum ...

Role of the Pipe Field Engineer in Safety

ROLE OF THE PIPE FIELD ENGINEER IN SAFETY

The Piping or Mechanical Field Engineer is a direct contributor to the safety of the work operations at the construction site. Since all safe work operations must begin with pre-planning, the Field Engineer makes a direct contribution to safety by reviewing the planned work with safety in mind. The Field Engineer is typically responsible to develop a detailed work package ... Read More »
