Units P106-113

Unit Description

Units P106-109 and P110-113 each have four parallel trickle bed reactors with integrated pre-heaters. This allows up to four candidate catalysts and/or feedstocks to be evaluated at the same time.

The reactors of each unit operate isothermally. They have an independent pre-heater, four shared heater blocks, two internal thermocouples (an inlet and an outlet), and two skin thermocouples (upper and lower).

The reactor specifications for P106-109 and P110-113 are as follows:

Additional attributes to note

  • The reactors are housed in a shared furnace ensuring that each reactor system is operated at the same temperature. Other process variables such as pressure, liquid flow rate, and gas flow rate, are independent and can be varied on a per reactor basis as needed.
  • These units are once-through units with no gas recycle or liquid recycle. 
  • Product fractionation, if required, is performed offline in batch distillation units. 
  • Process lines are steam-traced to allow for processing heavier, more viscous materials. 
  • Full attention unit with at least one Operator per shift.

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:

Common Project Types:

These units have been primarily used to generate process data at multiple test points more quickly and more cost effectively when compared to a single independent unit. They have been used for:

  • Catalyst screening comparing up to four candidate catalysts side-by-side at one time while processing one feedstock.
  • Feedsdtock screening comparing up to four candidate feedstocks side-by-side at one time with the same catalyst in each reactor.
