    Recently, the serious problems have been occurred due to the contaminated sites with heavy metals are increasing. There are several remediation technologies of the metal contaminated soil such as physical separation, washing with water or acid, biologically, electrically. Pytoremediation, ultrasonic etc. Among these technologies the physical separation can be put in a good option to solve the metal contaminated soil economically and environmental friendly. Because this technology has been already commercially certificated in the mineral processing field for a long time.

    Recently problems of soil and groundwater contamination occur in major construction sites of highway, dam and railways. Contaminants of oil fuels are also detected in the former fuel storage facilities of railroad station and army troops of transportation, etc. These facilities are planned as the sites of commercial infrastructures after restoration from pollutants by the law of soil environment conservation of Korea. In this manuscript, the contents of soil environment conservation law including soil assessment and restoration technology are introduced. Recent changes of soil environment area are also analyzed.

    The most common soil contaminants are petroleum-based. Hydrocarbons from diesel fuel and gasoline are widespread problems, as are total petroleum hydrocarbon(TPH). There are two distinct classes of soil remediation: in-situ, or on-site, and ex-situ, or off- site. On-site cleanups are often preferred because they are cheaper. On the other hand, excavating a contaminated area and transporting it to a remote site before cleaning it can often be more complete. Ex-situ remediation also has the added bonus of taking the bulk of contaminants off-site before they can spread further. In addition, in-situ situations are limited because only the topside of the soil is accessible.

    Many traditional architectures of Korea were lost due to fire accident caused by various reasons. It has been reported that faulty electric facility is the major cause of fire. Protecting and preserving the traditional architectures under current management system and electric facility regulation are difficult. Therefore establishing early stage fire extinguishment process and management system is urgent as well as eliminating the cause of fire.

    Considering domestic situation such as economical crisis, $CO_2$ exhaust amount limit based on the Climatic Change Convention, sky-rocketed oil prices. 97% of energy import from abroad, and import sum reaching up to 20% of entire import, we need to invest new recycle energy and future energy development at a full blast.

    Recently most companies require various type of energy sources, in order to be more energy efficient in their plant due to the increasing current oil price. So, the multi-national companies are shaping ideas how to reduce energy costs and use substitute energy. The purpose of this study Is to attempt to save energy by making more valuable high pressure steam through TVR(Thermal Vapor Recompressor) from the surplus low pressure steam of HRB(Heat Recovery Boiler) in sulfuric acid plant.
