Workshop, Seminar and Short Course

Department of Chemical Engineering, BUET organizes regular workshops, short-courses and seminar for the practitioners and academics. The department has recently organized two two-day long workshops for the engineers to raise their capability in the field of ‘process simulation and optimization’ and ‘process safety and risk management’. Apart from these, ChE department has also staged a seminar on Biomedical Engineering. The cross-sections of the events are presented below:


Chemical Process design and simulation have become much easier nowadays. Various process design software like HYSYS, Design 2, gPROMS have made the tedious and time consuming calculations of flow sheeting simple and time effective. Optimization of the process and costing can also be done using such software; however, the usefulness of these software largely depends on the skill of their users. Thus, the skill required to design or renovate a process plant by using process simulation software is as important as the physical and chemical insights into the process.

By considering the necessity of the skill to use process simulation software, the Department of Chemical Engineering, BUET organized a basic workshop on simulation software, HYSYS, on October 7 – 8, 2010. The main objective of the workshop was to familiarize the plant personnel with the working environment of the software and to help them know what the input variables are for performing the operations like flow sheeting, equipment design, costing and optimization.

Prof. Dil Afroza Begum, the head of the Dept. of Chemical Engineering at BUET inaugurated the workshop on October 7; she also coordinated the workshop. Dr. Ruhul Amin, Dr. Tanvir Sowgath, Mr. B.M. Sirajeel Arifin and Mr. K.M. Tanvir Ahmmed were the resource persons of the workshop. Thirty participants took part in the workshop; the participants came from different local industries and universities: Karnaphuli Fertilizer Company Ltd. (KAFCO), Bangladesh Petroleum Exploration & Production Commpany Ltd (BAPEX), Gas Transmission Company Limited (GTCL), Chevron Bangladesh, Tullow Bangladesh, Shahjalal University of Science and Technology (SUST), Sylhet Gas Field Ltd (SGFL), Urea Fertilizer Factory Ltd. (UFFL), Bangladesh Chemical Industries Corporation (BCIC) and so on.

This was an introductory workshop on Process Simulation using HYSYS intending to make the industry people know how to set-up a Process Flow Sheet in the simulation environment and how to solve the material and energy balances for different unit operations in steady state conditions. Both reactive and non-reactive processes were demonstrated. Participants were very much enthusiastic while setting up and solving the balances of reactors, heat-exchangers, pumps, expanders, distillation columns and performing the optimization and profitability. The workshop was highly interactive with a hands-on session in each lecture; participants were provided with printed and soft versions of the workshop materials.

At the end of the workshop the participants were awarded certificates. At the certificate giving ceremony, Prof. Iqbal Mahmood, Professor Emeritus and Ex-VC of BUET, was present as chief guest. Prof. Nooruddin Ahmed, UGC Professor and Ex-VC of BUET, Prof. A.K.M.A. Quader were present as special guests. Prof. Dil Afroza Begum presided over the ceremony

Abstract of Lecture

For noninvasive assessment of biochemical, pH and temperature variations in biological tissue, molecular imaging with MRI utilizing paramagnetic probes that affect water relaxation rate is the favored technology. However MRI (approaches have specifically limits that may confound quantitative measurements. While molecular imaging with MRSs far more definite as the signal origin, it is less preferred because of shortcomings (e.g., extremely poor sensitivity, very large voxels, long averaging times, confounding spectral overlap, sensitivity to shim, etc). He has presented evidence to advocate that molecular imaging with MRS is feasible employing a class of novel paramagnetic probes. Physical characteristics of the MRS signal from these probes provide novel traits which can overcome classical stigmas associated with MRS to enable highly specific molecular information, but at the speed of MRI. He also highlighted several potential biomedical applications.


The intensive practice of Process Safety in chemical industries was initiated in 1992 after the Bhopal disaster. The most recent BP’s deep sea horizon oil-spill in the Gulf of Mexico is an example of catastrophic incidents that can occur from a lack of proper safety technology and analysis. As a result, government and companies have put their first and foremost importance on safety and risk management. Bangladesh has a poor record in maintaining safety and minimizing losses. Serious breaches of safety have occurred in handling, transportation and storage of hazardous materials leading to deaths and financial losses.

Department of Chemical Engineering, BUET has come forward to spread the knowledge on this indispensable issue in Bangladesh. With the association of BUET Chemical Engineering Forum (BCEF), ChE dept has made a timely initiative to coach the academicians and practicing engineers by a two-day long short course on Process Safety and Risk Management. The global consummate authority in this regard, Prof. M. Sam Mannan, Regents Professor and Director, Mary Kay O’connor Process Safety Center (MKOPSC), Texas A & M University, USA, with his colleague Prof. Hans Pasman have enlightened more than hundred engineers and academicians with the positive benefits of process safety and risk management. The technical personnel were mainly chemical engineers, mechanical engineers, safety and health personnel, industrial hygiene personnel and operations and maintenance supervisors.

Despite being the Election Day at the Institute of Engineers Bangladesh (IEB), engineers’ biggest hub, the inaugural ceremony of the short-course was crowded with almost 200 engineers, academics and invited guests. Mr. Dilip Barua, Hon’ble Minister for Industries, Government of Bangladesh (GoB) graced the inaugural ceremony on December 9, 2010 as chief guest; Prof. S.M. Nazrul Islam, Hon’ble Vice-Chancellor, BUET was the special guest. Prof. Dil Afroza Begum, Head of the Dept. of Chemical Engineering, BUET, presided over the inaugural ceremony.

Dr. Jasimuz Zaman, Chairman of the BUET Chemical Engineering Forum (BCEF) and President of the Chemical Engineering Alumni Association (ChEAA) presented the welcome address. In his speech, Dr. Zaman described the different programs being undertaken by BCEF in supporting the development of the Dept. of Chemical Engineering, BUET. He anticipated that in future the Non-Residence Bangladeshi (NRB) engineers will play a role in the better development of BD engineering practice and research.

In the keynote presentation Prof. Mannan showed a number of the disastrous accidents that occurred in the chemical industries in the last century including the Bhopal accident, Chernobyl accident and recent Buncefield accident of UK in 2005. He emphasized that the safety features should be considered from the design stage of a Chemical Process Plant. According to the professor an old but inherently safer technology is better than the most advanced technology lacking proper safety measures. He also mentioned that more than 50% of the accidents occur due to the faults of human beings. So, safety training for plant personnel is a must.

The Vice-Chancellor of BUET and President of IEB, Prof. Islam emphasized on the importance of industrialization for the development of the country and restated that the industrial operations and work place must be kept safe. He requested the Hon’ble Minister of Industry to include engineers and technical persons in the National Safety Council. He also hoped that the nation will be self-sufficient in solving its crisis.

The chief guest, Hon’ble Minister for Industries Mr. Dilip Barua, assured Government’s continuing support in the field of Process Safety. He mentioned that the National Industrial Policy- 2010 emphasized on process safety and risk management issues in order to ensure green and eco-friendly industrialization. He thanked Prof. Sam Mannan for his willingness to contribute for the development of his home country and congratulated the dept. of Chemical Engineering for organizing such a timely short course.

The short course started after the inaugural session. Prof. Mannan covered Management System, Industrial Hygiene and Toxicology, Risk Analysis and Hazards Assessment, Hazards Identification and Hazard and Operability (HAZOP) Study Methodology in the first day of the event. With practical example, he showed how PMR (Prevention, Mitigation and Response) study is done for risk assessment. Regarding to the identification of the sources of risks, he emphasized on the proper identification of the problem to find out a simple solution.

In the following morning Prof. Pasman, the guest speaker lectured on the Consequence Analysis and elaborately explained the difference among Fire, Deflagration and Detonation. He finished the session with Inherently Safer Design Concepts and Multiple Layers of Protections. In his talk he also gave a direction for future research in this field. At the evening session of the workshop Dr. Mannan elucidated the concepts of HAZOP, What-if, Event Trees, Fault Trees, Relief Systems, Counter Measures and Emergency Measures with case studies. The course was interactive and lively with frequent questions from the participants in midst of the lectures. The resource persons happily answered them and expressed their pleasure about the quality of the audiences. Prof. Mannan expressed interest to organize more short-courses from his research centre on different specific topics.

On the final day of the short course a certificate giving ceremony was held. Prof. Iqbal Mahmood, Professor Emeritus and Ex-VC of BUET, was present as the chief guest and Dr. M. Sirajul Islam was present as the special guest of the ceremony.
