TUBE SIDE HOT FLUID


2 DIFFERNET CHECK VALVES WILL PREVENT FLOW CASE BUT NOT PRESSURE CASE


SPECTACLE BLIND WHEN NOZZLE NOT IN USE

Canned Pump

Canned motor pumps are preferred in the chemical and petrochemical industry, but also for simple pumping tasks, such as circulating pumps in industrial refrigeration equipment.

In general, the following media are conveyed: aggressive, toxic, explosive, hot, cryogenic, malodorous, volatile, flammable or carcinogenic substances – in brief, media that represent an environmental and health hazard.

Advantages of canned motor pumps at a glance:

  • Absolute leak tightness to the outside. Canned motor pumps meet the highest environmental protection standards.
  • Double containment shell to the atmosphere. The motor housing and terminal box are designed as pressure-containing parts and as a second containment shell.
  • Extremely low sound level
  • ZART® technology ensures non-contact, wear-free operation of the rotor unit
  • Practically no wear and minimal maintenance
  • High availability and long service life
  • Reduced maintenance and low life cycle costs
  • Higher MTBF values compared to conventional chemical pumps with mechanical seal
  • Easy installation, no alignment of motor and coupling required

 

·         Canned motors are employed wherever hot, aggressive, explosive, toxic or radioactive fluids need to be pumped, which is why a great deal of focus is placed on hermetically sealed pump sets without gland packings or mechanical seals. Canned motors are used for circulators reactor circulating pumps (see Reactor pump), and process pumps for chemical and process engineering applications.

Steam flooding

Stam inject and sweep oil to well

Canned – sump pump, not enough npsh, in our plant for solvent (500-600 kg/m³)

Impeller under the ground, impeller of the pump is underground to provide head for pump and suction

Solvent booster pumps are canned and solvent feed pump are canned type

 

0012 I scanned pump to be used

 

Lean or rich gluycool can be water content , can be solvent or water or gas content in gas or h2s or co2

Production crossover

 

ALL HEAT XCHNAGERSS ARE CONSIDERED AS A PRESSURE VESSEL SO THEY HAVE A PSV AS PER THE ASME CODE ON BOTH SIDES

 

 

ALL VESSELS COZ OF THE ACCUMULATION PRESSURE WILL HAVE PRESSURE CLASS CHANGE AT THE BOTTOM AND ITS BEST TO HAVE IT AT THE NOZZLE SINCE THE NOZZLE WILL HAVE A PRESSURE CLASS CHANGE ANYWAYS
