18、 health and environmental protection. For this, the following should be taken into consideration at the design stage: - selection of the least harmful process materials and intermediaries; muumization of the inventory of hazardous mmmwation of emissions of harmful solid, liquid . - 7 . - and gaseous
19、 substances; - design of combustion plant and equipment such as gas turbines, diesel and petrol engines, fiares and boilem to produce exhaust gas which conforms to the authorized emission contents for oxides of nitrogen and sulfur and other polutants; - location of plant to minimize the risk to neig
