What is difference between block flow diagram and process flow diagram?
BFDs provide a complete overview of the whole process in block diagram form. They summarise the major unit operation between process block units. PFDs characterize all the process flows to and from all the equipment required to perform the process within the boundaries set by the BFD
What is difference between unit operation and unit process?
process is a set of operation for example in a sugar mill the processing involve 1. bringing out juice from sugarcane. 2. heat them. 3.refine them.etc. here process is the combination of all of the above stated tasks (1,2,3,). on the contrary, each of the tasks of a process is operation for example the task 1,2,3, each are operation.
What is a Process Flow Diagram?
A Process Flow Diagram (or System Flow Diagram) shows the relationships between the major components in the system. It also has basic information concerning the material balance for the process. See the related link.
What is the difference in process flow diagram and piping and instrumentation diagram?
p&ids r docs used to desribe symbols,abbreivations prefixes and specialised equipments while pfds r sketches that use symbols to represent instruments/vessels used in process engrn and also shows the direction of flow.
What is the meaning of crack in Oil industry?
In the oil industry, "crack" refers to the process of breaking down crude oil into its various components, primarily through a method called cracking. This process involves heating the crude oil and breaking its long hydrocarbon chains into shorter, more valuable products like gasoline, diesel, and jet fuel. The term also commonly relates to the "crack spread," which is the financial metric used to assess the profitability of refining crude oil into these products, reflecting the price difference between crude oil and refined products.
What is the difference between testing and commissioning?
Systems Commissioning is the process of testing final versions of software, hardware and configuration in their final locations. Once completed, it is "Live" (Available for use) and will not require further testing.
What is difference commisioning and pre-commisio?
Commissioning typically refers to the process of verifying and ensuring that a system or equipment is installed correctly and operates as intended. Pre-commissioning usually involves initial testing and checks before the formal commissioning process to make sure that everything is ready for full commissioning. Pre-commissioning is a preparatory phase before commissioning.
What is the difference between plant start up and plant commissioning?
Testing and commissioning are to be carried out on installations to assure that they are reliable and meet the design requirements. The witnessing of tests on and off-site shall be determined by Design specifications, Mechanical and Electrical
