We steam strip for one hour at 12k steam, then cut the rate back to 6k to keep the inlet clear while we depressure the drum. After we depresure the drum to a suitable drum pressure we introduce water. When we do this “water check” we open the control valve wide open until we get over 1kgpm introduced to ensure that inlet is clear, we then cut the rate back to minimum.
