The existence of real learning beyond the four walls of the classroom, with this objective industrial visit, was organized for the B. E. Semester-6 students of Chemical Engineering Department. Total 42 Students of the B. E. Semester-6 along with two faculty coordinators Prof. Jay Trivedi and Dr. Ujvala Christian visited Dwarkesh Chemicals Ltd. (a N-PROPYL BROMIDE and N-BUTYL BROMIDE manufacturing plant), in G.I.D.C, Phase-III, Vatva, Ahmedabad. Dwarkesh Chemicals was established in 1986 by a dynamic, visionary and hardworking team. Starting with a capacity of 25MT they have scaled up to the production of 1500MT per annum without compromising on quality. Industry will plan to scale up to 5000MT and add a whole new array of products.

Key Features:

• Organizing Department: Chemical Engineering Department 
• Name of the Industry: Dwarkesh Chemicals Ltd. G.I.D.C, Phase-III, Vatva-Ahmedabad. 
• Day and Date of Visit: Wednesday 25th February,2026 
• No. of Students: 42
• Faculty Coordinators: Prof. J. B. Trivedi and Dr. U. P. Christian, Assistant Professor         Chemical Engineering Department, VGEC.

Visit Insight:

Students visited the production unit where bromine, catalyst and n-butyl were used to form the N-BUTYL BROMIDE and N-PROPYL BROMIDE:

• Bromine in liquid form of 3 Kg capacity (kept in bottles) are purchased and stored in stacks as per safety guidelines. It further undergoes halogenations reaction with N-Butylene and N-Propylene in the glass- lined batch reactor.
• Sulfuric acid is generated as a by-product during the reaction process.
• Working of major process equipment like Distillation Column, Batch Agitated Reactor, Condenser, Cooling tower, ETP plant, high density pump, etc. were explained.  
• The waste water generated is processed in the Effluent Treatment Plant (ETP) of GIDC Vatva under the guidelines of GPCB.
• Final Product purity is tested using Gas Chromatography method. Working of Analytical Gas Chromatography equipment was demonstrated with actual sample analysis.

Outcomes:

• Students got the opportunity to interact with the owner of industry and plant personnel who explained process and working of different process equipment in detail.
