  13. What is the use of steam jet ejectors?

    Steam jet ejjector can be use to creat a vacuume and it can be also use as thermocompressor...e.g inmultiple effect evaporator it can be use as a vacuume creator and also also it can be use as thermocompressor
  14. question

    im stuck in one question , can anyone help me out ??? Problem Description Normal butane, C4H10, is to be isomerized to isobutane in a plug-flow reactor. This elementary reversible reaction is to be carried out adiabatically in the liquid phase under high pressure using a liquid catalyst which gives a specific reaction rate of 31.1 h-1 at 360 K. The feed enters at 330 K. Calculate the PFR volume necessary to process 100,000 gal/day (160 kmol/h) at 70% conversion of a mixture 90 mol % n-butane and 10 mol % of i-pentane, which is considered an inert. Plot and analyze X, Xe, T and -rA down the length of the reactor Calculate the CSTR volume for the same conditions as the PFR

  16. Centrifugal Pump use Impeller to flow the liquid, while P.D pumps use screw, gear or piston etc to flow the liquid. Centrifugal pumps usually use for high flow rate and low pressure while P.D pumps use for the opposite operation of centrifugal pump. Centrifugal gives continuous flow of liquid while PD pumps give Pulsive flow with high pressure.

  20. Centrifugal pumps and positive displacement pumps are the teo major classes of pumps. Positive displacement pumps directly apply pressure on liquids by reciprocating of piston or by rotating members which form chambers alternatively filled and emptied. Centrifugal pumps on the other hand generates high rotational velocities and then convert resulting kinetic energy of the liquid to pressure energy.
  21. Petroleum

    I am a chemical engineering graduate and I want to pursue my career in petroleum industry. What courses should I do in order to get a job in that particular industry. Or are there any other sources to get a job for freshers and what are the skills required that I should work on?

  24. What is the use of steam jet ejectors?

    Steam ejector is helpful to create a vacuum in process equipment let's take an example in a process plant there is only stripper of distillation here their was a steam jet ejector it sucks the 8 bar steam out if distillation and sent this steam to process and on the other hand it is creating a vacuum inside the stripper so there are 2 advantage
  25. Centrifugal pump is use for pumping low viscous fluids where as PD pump is use for high viscous fluid centrifugal pump is use when we required continuous high flow rate where as PD PUMP for low flow rate Centrifugal works on centrifugal force and PD works as, first it will suck and then discharge with the help of piston Priming has to be done in centrifugal pump to avoid cavitation, no need such activity in PD pump Note : PD means positive displacement
