The turbo expander and absorber tower can be considered to be the heart and lungs of the unit. Cryogenic absorbers may be trayed or packed and will be designed to provide sufficient vapour liquid contact to achieve the required overheads and bottoms product specification.
The operations technician will be able to:
identify and correct operational problems
determine the impact of composition changes
liaise with maintenance to schedule equipment availability.
This competency would be undertaken within a team environment and in conjunction with the overall control of the product being produced.
A typical example of liquid extraction occurs in a natural gas processing plant and contains an absorber, de-ethaniser tower, turbo expander compressor, cold separator vessel and various plate fin type heat exchangers. An operations technician would be monitoring and controlling this process in order to achieve condensation of all the desired product to meet a predetermined specification.
