What is hot utility?
Hot utility is produced directly by heating water with the ethylene stream.
The study comprises the production of high and low pressures steam, and hot water needed in the process.
Using both lines, ethylene temperature can be at 230 °C..
What utility means?
Utility is a term in economics that refers to the total satisfaction received from consuming a good or service. Economic theories based on rational choice usually assume that consumers will strive to maximize their utility. … In practice, a consumer’s utility is impossible to measure and quantify.
What is Process Utility?
Processing utilities allow you to run Optim™ processes (such as Extract, Archive, Insert, Convert, Compare, Delete, Search, and Restore) in batch mode. You can create batch jobs in the following two ways: Enter the job parameters directly in an editor, using the Batch Utility control statements.
How do you draw a 3d curve?
Draw a Helical CurveIn an active 3D sketch, click 3D Sketch tab Draw panel Helical Curve .In the Helical Shape tab of the Helical Curve dialog box, choose a Type: … Select a Definition type to choose the parameters you want to use to define the curve: … Enter values for the type of shape you specified:More items…•
How do you add a derived sketch in Solidworks?
Deriving Sketches in PartsSelect the sketch from which you want to derive a new sketch.Hold the Ctrl key and click the face on which you want to place the new sketch.Click Insert > Derived Sketch. … Position the derived sketch by dragging and dimensioning it to the selected face. … Exit the sketch.
What is pinch temperature?
“Pinch” is the point of closest approach between the hot and cold streams in the T vs. H diagram. Temperature profiles (temperature vs. distance diagram) of hot stream (flowing from left to right) and cold stream (flowing from right to left) in counter-flow heat exchanger of above case.
How do you do a pinch analysis?
The pinch analysis is a structured method which involves the following steps:Map all process streams inside and in the vicinity of the plant and compose a mass and energy balance.Put the different process streams in a table that shows their supply temperature, desired temperature and heat capacity.More items…
How do you curve in Solidworks?
on the Curves toolbar, or Insert > Curve > Projected. Use this selection to project a sketched curve onto a model face. , select the curve in the graphics area or from the flyout FeatureManager design tree. , select the cylindrical face on the model where you want to project the sketch.
How do you curve a solidworks project?
To project a curve: Click Project Curve on the Curves toolbar, or Insert > Curve > Projected. Use this selection to project a sketched curve onto a model face. Under Sketch to Project , select the curve in the graphics area or from the flyout FeatureManager design tree.
What is grand composite curve?
The grand composite curve is a graphical representation of the excess heat available to a process within each temperature interval. … Once we have satisfied the demand for heat at lower temperature intervals, we apply cooling utilities to remove the remaining heat.
How do you draw a composite curve in Solidworks?
Creating Composite CurvesClick Composite Curve. on the Curves toolbar, or click Insert > Curve > Composite.Click the items (sketch entities, edges, and so on) that you want to join. The selected items appear in the Composite Curve PropertyManager, under Entities to Join in the Sketches, Edges, and Curves to Join. … Click .
What is minimum approach temperature?
The minimum approach temperature represents the smallest gap in temperature across which heat transfer will occur in the system. This often only occurs at the pinch. While technically any value greater than zero can allow for heat transfer, very small values are not often feasible.
What is a pinch point engineering?
Pinch Point Analysis is a systematic process design methodology consisting of a number of concepts and techniques that ensure an optimal use of energy. The Pinch is characterized by a minimum temperature difference between hot and cold streams and designates the location where the heat recovery is the most constraint.
What is pinch point in boiler?
Pinch point is the difference between the gas temperature leaving the evaporator and saturation temperature=Tg3-ts. Fig 1: HRSG temperature profiles. Approach point is the difference between saturation temperature and feed water temperature entering the evaporator= ts -tw2.
