The aim of this course is to familiarize students with the fuel characteristics, technical and medical gases, and to acquire academic skills and competencies for selection and calculation of equipment of gas installations. Through this course student mastery specific practical skills for work in the design and calculation of pipelines and fittings, storage tanks and other equipment for gas. Through laboratory student acquire knowledge related to testing of equipment for gas.

Successful completion of the study program the student receives the following general skills: analysis, synthesis and forecasting solutions and consequences, and develop critical thinking and self-critical approach, application of knowledge in practice, professional ethics, linking knowledge from different fields and their applications, development of skill and dexterity in the use of knowledge in the field of distribution and transportation of natural gas storage and technical gases.

Natural gas, LPG, other fuel gases. Types and equipment for Gas Pressure Regulating Stations and Gas Pressure Regulating and Metering Stations. Types of devices for inner gas installations, safety equipment, removal of combustion products. Technical gases: air, atmospheric gases, hydrogen, chlorine… – characteristics and applications. Equipment of installations for storage and distribution. Production of atmospheric gases. Cleaning and preparation of installations. Gas bottles an tanks for gas storage, pilot regulators, gas pressure regulators, safety blow – off and relief valves, check valves, gas filters, heat exchangers, pipe insulating connections, control device accessories , odorizers , ball valves , electromagnetic valves, flow rate regulators, gas regulating and metering stations.

Gas composition, pressure drops, odorisation. Pipe sizing, level of security, material characteristics. Classification and elements of gas pipelines. Hydraulic calculation of gas pipelines.
