Steam, electricity and cooling-water checklist for evaporators

Prepare the utility data needed for steam, TVR or MVR falling film evaporation: pressures, electrical capacity, cooling conditions and operating hours.

01 / SELECTION

Describe the heating supply

Give available steam pressure, normal variation, quality and condensate-return conditions. Identify whether feed preheating is inside the evaporator scope. For TVR, the motive-steam basis is especially important because it affects the recompression operating point.

02 / SELECTION

Describe the electrical service

For an MVR option, state supply voltage and frequency, available power, motor and drive requirements and any start-up restrictions. Pumps, controls and auxiliaries also consume electricity. Ask for the normal and peak utility schedule rather than only one headline compressor figure.

03 / SELECTION

Describe heat rejection and vacuum services

Give cooling-water inlet temperature, allowable outlet temperature, available flow and seasonal variation. State whether a closed cooling circuit or another heat sink is proposed. Condensing capacity and non-condensable removal help establish the pressure profile; an unspecified vacuum figure is not a complete utility basis.

04 / SELECTION

Compare annual operation on the same basis

Provide production hours, batch or continuous schedule, expected minimum load and product-change frequency. Include start-up, shutdown and cleaning in the comparison. Utility economics should use site prices and an agreed heat balance rather than an unqualified percentage saving.
