  • Rotary Evaporators
    Rotary evaporators (also called "rotavaps") are used to remove solvents from reaction mixtures and can accommodate volumes as large as three liters. They are found in almost every organic laboratory. A typical rotary evaporator has a heatable water bath to keep the solvent from freezing during
  • The World's Largest Thin Film Short Path Evaporator
    We recently described starting up the World's Largest Short Path Evaporator. Now GIG Karasek has completed another client benchmark challenge. Here is the challenge:
  • Flow Induced Noise Emanating from Evaporator Tube Plates (.pdf)
    This work examines, objectively and subjectively, refrigerant noise induced by the flow of R134a through seven different plate-type automotive evaporator tubes with two tube heights and airflow depths ranging from about 45 mm to 75 mm. Experiments were conducted with both superheated and two-phase
  • Caravan Ingredients Uses Artisan Evaporator/Stripper TM to Improve Monoglyceride Production (.pd)
    Caravan Ingredients, a leading supplier of food emulsifiers, was using vertical wiped-film evaporators to recover monoglyceride. The process required recycle during startup to achieve product purity, yield was marginal, and frequent shutdown for mechanical repair was raising operating costs
  • Overall Equipment Efficiency Improvement for GaAs Fab Evaporators
    This paper reviews how six sigma methodology principles and total preventive maintenance (TPM) drains analysis have been utilized to increase overall equipment effectiveness (OEE) on the metal deposition operation in our GaAs wafer fab.
  • Brazing two aluminum pipes to aluminum evaporator core [PFS]
    The customer is replacing a flame process which can burn away the thin flange at the joint area and create scrap parts. By switching to induction for this application the customer is decreasing their scrap parts and also increasing their quality and production rate...
  • Brazing two aluminum pipes to aluminum evaporator core [IH]
    The customer is replacing a flame process which can burn away the thin flange at the joint area and create scrap parts. By switching to induction for this application the customer is decreasing their scrap parts and also increasing their quality and production rate...
  • Advanced Process Control: Bridge the Gap
    exceeded this objective, reducing the variation by approximately 73% for Evaporator 1 and 68% for Evaporator 2. The reduction in standard deviation of evaporator total solids will allow operations to increase total solids targets in the evaporators without violating viscosity limits. This allows increased
