The vector stencils library "Chemical engineering" contains 24 symbols of chemical and process engineering equipment.
Use these shapes for drawing block flow diagrams (BFD), process flow diagrams (PFD), piping and instrumentation diagrams (P&ID), and water flow diagrams.
"Chemical engineering is a branch of engineering that applies the natural (or experimental) sciences (e.g., chemistry and physics) and life sciences (e.g. biology, microbiology and biochemistry) together with mathematics and economics to production, transformation, transportation and proper usage of chemicals, materials and energy. It essentially deals with the engineering of chemicals, energy and the processes that create and/ or convert them. Modern chemical engineers are concerned with processes that convert raw-materials or (cheap)chemicals into more useful or valuable forms. In addition, they are also concerned with pioneering valuable materials and related techniques – which are often essential to related fields such as nanotechnology, fuel cells and bioengineering. Within chemical engineering, two broad subgroups include design, manufacture, and operation of plants and machinery in industrial chemical and related processes ("chemical process engineers") and development of new or adapted substances for products ranging from foods and beverages to cosmetics to cleaners to pharmaceutical ingredients, among many other products ("chemical product engineers")."

The example "Design elements - Chemical engineering" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Chemical and Process Engineering solution from the Engineering area of ConceptDraw Solution Park.

The vector stencils library "Heating equipment" contains 42 symbols of regenerators, intercoolers, heaters, and condensers.
Use these shapes for drawing cooling systems, heat recovery systems, thermal, heat transfer and mechanical design, and process flow diagrams (PFD).
"Heating or cooling of processes, equipment, or enclosed environments are within the purview of thermal engineering.
One or more of the following disciplines may be involved in solving a particular thermal engineering problem:
Thermodynamics,
Fluid mechanics,
Heat transfer,
Mass transfer.
Thermal engineering may be practiced by mechanical engineers and chemical engineers.
One branch of knowledge used frequently in thermal engineering is that of thermofluids." [Thermal engineering. Wikipedia]
