Registration and Cancellation Policy

Registration Policy

AIChE's meeting registration policy is based on the premise that AIChE's conferences and meetings are amongst the most prestigious and best attended chemical engineering conferences in the world. Participation in these conferences is beneficial to the individual and his/her company or institution, as it provides individual and company/institution exposure, networking, and the possibility to make lasting connections. Presentation of a paper is felt to be only one form of participation along with chairing sessions, attending sessions and presentations, and participating in business meetings or other collegial activities.

Therefore, all participants, including speakers (invited or accepted through the Call for Abstracts), are expected to register and pay the appropriate registration fee.

AIChE Spring and Annual Meeting Specifics

All particpants are expected to adhere to the registration policy. However, in certain instances, a waiver may be requested. All requests sent after the end of the early registration deadline will not be granted. Requests must come in through the appropriate Division, Forum, or Topical Conference Program Chair to be considered.

If approved, only a one-day registration waiver will be granted. In no case should a commitment be made to any speaker without prior approval of the AIChE Program Development Department.

If organizers such as Division, Forum, or Topical Conference Chairs feel that a particular speaker is especially important to the effective implementation of the conference and the invited speaker(s) are attending exclusively to present an invited paper, a request can be forwarded to the AIChE Program Development Department ( requesting a fee waiver.
