chemical engineering The branch of engineering concerned with industrial manufacture of chemical products. It is a discipline in which the principles of mathematical, physical and natural sciences are used to solve problems in applied chemistry. Chemical engineers design, develop, and optimise processes and plants, operate them, manage personnel and capital, and conduct research necessary for new developments. Through their efforts, new petroleum products, plastics, agricultural chemicals, house-hold products, pharmaceuticals, electronic and advanced materials, photographic materials, chemical and biological compounds, various food and other products evolvekimya mühendisliği
chemical fallout The sedimentation of chemical substances accumulated in the atmosphere as a result of industrial emissionskimyasal serpinti
chemical fertiliser Fertilizer manufactured from chemicals; excessive use of them can cause pollution, when all the chemicals are not taken up by the plants and the excess is leached out of the soil into rivers and may cause algal bloomkimyasal gübre
chemical in the environment The presence in the environment of any solid, liquid or gaseous material discharged from a process and that may pose substantial hazard to human health and the environmentortamdaki kimyasal maddeler
chemical industry Industry related with the production of chemical compounds. The chemical processing industry has a variety of special pollution problems due to the vast number of products manufactured. The treatment processes combine processing, concentration, separation, extraction, by-product recovery, destruction, and reduction in concentration. The wastes may originate from solvent extraction, acid and caustic wastes, overflows, spills, mechanical loss, etc.kimya sanayi
