Kelvin Power – Pre-feasibility study into demin water supply risks

Client: Kelvin Power
Purpose: Development and justify a cost effective solution to mitigate the risk associated with the existing B station demin water plant.
Steam pressure: N/A
Steam temperature: N/A
Mass flowrate: 60 – 100 T/Hr
Fuel: N/A
Project type: Brownfields/Greenfields

KELVIN POWER currently have concerns regarding the civil foundation around the existing demin plant. In response to this threat, KELVIN POWER is looking into a number of possible solutions to mitigate this risk. The project involved the consolidation of the proposed solutions into a “decision matrix” to better manage the decision making process. A number of factors were considered in evaluating each option, namely, Process, Environmental, Commercial and Risk. A high level 3D layout model was developed of the identified solution.

SAPPI – Air heater, condensate system design

Client: SAPPI
Purpose: Redesign the condensate system to reduce steam hammer and improve control
Steam pressure: 62 bar and 3.2 bar
Steam temperature: 285 oC
Mass flowrate: 8 T/hr
Fuel: N/A
Project type: Brownfields

A new air heater system was installed to supply hot air (260 oC) to an evaporation plant. The air heating system made use of Low Pressure (LP) and High Presure (HP) steam to heat the air via fin and tube heat excahngers, which were arrranged in series. High water hammer was being expereinced at the condensate side of the LP steam system and the failure of the HP steam traps was a major concern. A new control philosophywas developed and appropriate modifications proposed to mitigate the steam trap failures and water hammer concerns, whilst improving the control assocaited with each of the heater banks and the subsequent exhaust air temperatures.
