Design and Control of Acetaldehyde Production Process
Abstract: This paper discusses the steady state and dynamic simulations of acetaldehyde production process by using Aspen Plus and Aspen Dynamics. The model developed in the present study is the modification of the process developed by Eastman Chemical Company of U.S. Patent 6,121,498. The proposed design consists of a FEHE (feed effluent heat exchanger), reactor, absorption column, compressors and two distillation columns. Acetic acid reacts with hydrogen and gives acetaldehyde as …

Skill Development in Suctioning Technique among Caregivers of Patients Going to be Discharged with Tracheostomy Tube in situ
Abstract: Most of the patients (whose GCS is more than 8) are discharged from Neurosurgery Departments with tracheostomy tube in situ. Periodical suctioning is required to maintain the airway patent. The caregivers need to learn the technique of suctioning. The current study was undertaken with the objective to develop skills in suctioning technique among the caregivers of the patients going to be discharged with tracheostomy tube in situ. An interventional study …
