Chemical Engineering: Introduction

Chemical Engineering is one of the oldest branches of Engineering. Origin of this branch can be traced back to 1839, when this branch was mentioned in relation to production of sulfuric acid. Chemical Engineering touches our daily lives directly or indirectly in many ways. Also check – List of government jobs after completing diploma in India.


We all know about Chemistry. It is a branch that deals with composition, structure, properties and change of matter. It can be said to a central science that links other sciences such as physics and biology.


Chemical Engineering has the science of chemistry at its heart. But, overall, it is more than just plain science of chemistry. Want a proper definition of Chemical Engineering? Here it is-


Chemical Engineering is a branch of Engineering that applies concepts of physics, chemistry, biology, mathematics and economics to produce, transform, transport and use chemicals, materials (raw materials, products or by products) and energy.


Chemical reaction engineering, Process design and engineering, Plant design, Safety and hazard management, Energy, Chemical storage and transportation etc are integral parts of Chemical Engineering.


Chemical Engineering discipline touches our day to day lives in many ways. This discipline plays active role in sectors such as Pharmaceutical production, Food processing, Water purification, Sanitation, Textiles, Petrochemicals, Everyday materials (Rubber, Plastic, Polymers, Cleansing agents etc).


The above paragraph denotes how varied are the applications of Chemical Engineering. Job opportunities and profiles also are diverse, when it comes to this field.


Let us check out the course details now. Here are important details about Diploma in Chemical Engineering that you should know-


Diploma in Chemical Engineering: Course details

Diploma in Chemical Engineering is a 3 years long program. The academic program is divided into 6 semesters, with each semester lasting for a period of 6 months.


Few institutes are also offering Integrated program- Diploma + B.Tech. Degree in Chemical Engineering.


Diploma in Chemical Engineering course trains students in areas such as- Chemical reaction, production, storage, transportation of chemicals, raw materials, biochemistry, plant design, safety management etc.


Eligibility criteria

Students who have passed 10th standard are eligible to pursue this course. This course can also be pursued after 10+2 Science stream too (Mathematics group)!


Admission process and Colleges

Many polytechnic, technical education and engineering institutes across India are offering this program. Most institutes usually have the ‘direct admission’ process. Interested students have to approach the institute and fill up the admission form. Seats will be allotted to deserving students on the basis of marks scored by them in 10th board examination (usually in Mathematics and Science subjects).

Elective subjects may vary from one institute/university to another. Usually, elective subjects are related to topics like- Paper and Pulp Technology, Pharmaceutical Technology, Polymer Technology and Sugar & Food Technology.


Higher studies and PG courses

After completing Diploma in Chemical Engineering program, one may go for Bachelor’s Degree (B.E./B.Tech.) in Chemical Engineering! In most Degree Engineering colleges, certain percentages of seats are reserved for Diploma certificate holders. This entry is known as the lateral entry. Diploma holders with good grade may make use of lateral entry and join B.E./B.Tech. Chemical Engineering program’s 2nd academic year (directly). This way, Diploma holders may make the ‘DtoD’ switch and earn a Bachelor of Engineering/Technology Degree!
