The Black Liquor Evaporators - Equipment course describes several different evaporator designs that have been used to concentrate black liquor. These include rising film evaporators, falling film evaporators, falling film concentrators, and forced circulation concentrators. It also contains discussions on scaling and boil outs, the role of the surface condenser, overall driving force and capacity, and the removal of non-condensable gases from a multiple effect evaporator set.

At the end of this module, you will be able to:

  • List the objectives of black liquor evaporators
  • Differentiate between the designs and operation of several common types of black liquor evaporators and concentrators
  • Define "scaling" and recognize the need of a "boil-out"
  • Describe the role of the surface condenser
  • Describe overall driving force and capacity
  • State the importance of non-condensable gas (NCG) removal

The following key questions are answered in this module:

What is the primary purpose of black liquor evaporators?
The primary purpose of the black liquor evaporators is to evaporate water vapor and increase the concentration of the solids in the liquor.

Falling film evaporators have some advantages over rising film evaporators. What is their major disadvantage?
Falling film evaporators require a recirculation pump which increases the operating costs of this type of evaporator.

What is the difference between black liquor concentrators and evaporators?
Black liquor concentrators have design features to deal with the viscosity and salts which precipitate out of the liquor at higher concentrations.

What is the role of a surface condenser in a mulitple effect evaporator set?
The surface condenser condenses vapor from the lowest pressure effect, creating a vacuum which drives vapor flow through the set.

How do non-condensible gases affect evaporator performance?
NCGs on the vapor side of an evaporator set interfere with the movement and condensation of water vapor, causing a drop in evaporator capacity.

Below is a transcript of the video sample provided for this module:

There are several different evaporator designs used to concentrate black liquor, and they all contain two major parts. The first is the heating element, usually a vertically-arranged heat exchanger where the vapor or steam condenses and transfers its heat to the black liquor. The second part is the vapor body, also referred to as the vapor head or dome, which provides space for the concentrated liquor and water vapor to separate. The heating element is designed to provide as much surface area as possible for the vapor to condense and transfer heat to the liquor. The more heating surface that is available, the more the solution can be heated. Sets of tubes or parallel plates are commonly used. Black liquor and vapor or steam are both continuously fed into the evaporator, and concentrated liquor, water vapor, and condensate are all continuously discharged.

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
