  1. 16. Maintenance optimisation of centrifugal pumps in a European refinery: : A case study

    Master-uppsats, KTH/Industriell produktion

    Författare :Andrei Laquet; [2015]
    Nyckelord :;

    Sammanfattning : Maintenance has gained credit over the past decades. The oil and gas industry requires efficient maintenance programs due to the hazardousness surrounding the industry. Crude oil margins are also dropping and maintenance yields high controllable costs. Therefore, safety and economy are the driving forces of maintenance optimisation. LÄS MER

  5. 19. Treatment Technology for VOC Emissions from Oil Refineries : Case study of measures taken to minimize VOC emissions at Swedish petrochemical companies to be appiled at Chineses Refineries

    Master-uppsats, KTH/Industriell ekologi

    Författare :Hanna Odén; [2010]
    Nyckelord :VOC; VOC treatment; refinery; petrochemical industry; Tianjin; vapor recovery; VOC; flyktiga kolväten; VOC-behandling; raffinaderi; petrokemisk industri; Tianjin;

    Sammanfattning : The aim of this thesis is to give suggestions on what measures to take to improve the VOC emission situation in refineries in Tianjin, China, through existing technologies in refineries in Sweden. This has been done by identifying the main places of leakage in oil refineries in Sweden, identifying what VOC compounds are emitted from the plants and the amounts emitted, mapping out different measures taken by oil refineries in Sweden to minimize VOC emissions, evaluating the different measures and suggesting how to move forward with VOC control in Tianjin.
