Distillation

Distillation and fractionation pilot plant services

Process Description:

Distillation, also known as fractionation, is a process that separates a feedstock into its separate components by taking advantage of the difference in boiling points of the individual components.  A separation of this type can occur either continuously or in a batch process.

Batch Distillation:

All of the 12 batch distillation units available consist of a still pot in which the feed is charged and where the majority of the heat is applied, a column through which vapor from the still pot rises, an overhead condenser to cool rising overhead vapors back into the liquid state, and a product collection system to capture the condensed liquid as product.  The units differ in still pot size, efficiency, material of construction, column height, and column packing type. Additionally, some units have column heating (depending on the height of the column).  Most of the batch distillation units can operate under atmospheric conditions or under vacuum.  It should also be noted that none of the units are equipped to take side draw product collection.  Each unit produces an overhead product and bottoms product only; however, multiple overhead fractions can be generated in sequence.  A breakdown of the batch distillation units available is as follows:

Continuous Distillation:

Both of the continuous distillation units available consist of a feed delivery system, a column, and product collection of one bottoms fraction and one overhead fraction.  The units differ greatly in the feed delivery rate, column design, and fractionation efficiency.  A breakdown of the continuous distillation units available is as follows:

Analytical Support:

Analytical types and frequency are performed on an as needed basis to ensure that customers are getting only the data they need when they need it. Onsite and external analytical support options are available for characterization and unit control purposes.

In-house analytical support for unit control and external analytical support via the Intertek network of laboratories is as follows:

In-house:

  • D287 Density
  • D4052 Density
  • D2887 GC Distillation
  • D6352 GC Distillation

Intertek network:

  • D7169 GC Distillation

 

Common Project Types:

The batch distillation units are primarily used for:

  • Custom crude assays.
  • Generation of products for use in customer facility.
  • Preparation of a feedstock for a pilot program.
  • Product characterization of a product from a pilot program.

The continuous distillation units are primarily used for:

  • Generation of products for use in customer facility.
  • Preparation of a feedstock for a pilot program.
