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.

Learning Objectives

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

Key Questions

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.

Sample Video Transcript

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.

Customer Q&A

I would like to have several employees take multiple courses. How can I set that up?

We're in the process of making bulk course and multiple user purchases easier. But for now, you can order multiple courses and contact us with details on who you'd like to assign courses to. We can set up each user's training plan and make sure everyone gets the eLearning assignments they need.

Can I get a free full-length preview of a course to see what this course covers?

While we do our best to offer details on course contents, we don't normally offer full-length previews. But please contact us with more details for a better understanding of what your organizaton needs and how we can help.

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 each eLearning course.

How do I log in to take a course that I have already paid for?

You'll receive an email with login details moments after you purchase your pay-per-view (PPV) course. Just click the login link and enter the user name and password provided.

Do you have courses in different languages?

Yes. While all of our courses are originally produced in English, we develop many courses in a growing number of languages, including Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Tamil, and Thai. Available languages are normally displayed in the Course Details section on each course page.
