Working together with people from all walks of life, chemical engineers help to keep the world going and better. Like all engineers, we design and build equipments, then make them work safely and economically. These are mostly business-to-business activities, often outside public eyes. We specialize on activities that involve chemical and biochemical changes on a large scale. For example, we purify crude oil into petrol, kerosene and diesel that transport everyone around. We too make plastics and their biodegradable versions.
