What is the main function of a chemical-technological system?

• To transform raw materials into desired products through chemical and physical processes

• To store products before shipment

• To provide lighting and ventilation in a plant

• To control financial reporting

• To clean the equipment externally

Which of the following is a primary element of a chemical-technological system?

• Reactor

• Valve

• Pipeline

• Laboratory stuff

• Transport vehicle

In a chemical-technological system, auxiliary units serve what purpose?

• They support the main technological process, such as heating or purification

• They include systems like heat exchangers and compressors

• They are only for quality control

• They are unrelated to the process

• They produce waste products only

What distinguishes an open chemical-technological system from a closed one?

• It exchanges matter and energy with the environment

• It maintains internal pressure only

• It allows the input of raw materials and the output of products continuously

• It uses only recycled materials

• It does not require human control

What is the purpose of analyzing material efficiency in a chemical process?

• A. To evaluate how well raw materials are converted into products

• To compare brands of raw materials

• To track employee usage of chemicals

• To identify color changes in products

• To monitor noise levels

Which of the following indicates energy efficiency in chemical production?

• Maximum use of heating systems

• Minimal energy consumption per unit of product

• Frequent maintenance of electrical panels

• Continuous lighting of the facility

• Long process duration

What does a chemical-technological scheme represent?

• A graphical representation of all process stages and equipment

• A list of equipment

• A safety inspection form

• A chemical reaction equation

• A product label

Why is it important for a scheme to show material flow direction?

• To allow employees to design labels

• To help operators understand the production sequence

• To reduce the need for automation

• To improve office layout

• To guide visitors through the plant

What is typically shown using dotted lines in such schemes?

• Waste storage units

• Laboratory reactions

• Major connections

• Control and instrumentation flows

• Raw material orders

In a full structural scheme, feedback loops indicate:

• Recirculation or recycling of intermediate products

• Breakdowns in communication

• Employee complaints

• Raw material orders

• External audit reports
