Denholm Oilfield Services provides non-intrusive and intrusive decontamination services to the oil and gas industry.

These services have produced proven results for:

  • Process vessels and tanks
  • Large diameter crude storage tanks
  • Refineries and petrochemical plants
  • LSA / NORM decontamination

We have been at the forefront of developing new technologies and processes using chemical cleaning non-intrusive techniques which provide the following benefits:

  • Non-intrusive cleaning with no manned entry or roof entry required
  • Maximum recovery of usable hydrocarbons from solids and deposits to the client inventory
  • Separation of water from emulsions to a quality where it can be disposed to normal water treatment units
  • Elimination of H2S and pyrophoric iron sulphide and liberation of benzene and Low Explosive Limit (LEL) gases in preparation for manned entry
  • Minimising of the remaining sludge and solids for subsequent managed disposal

The process utilises the Zyme-flow range of products for whom Denholm MacNamee are the licence holder in the United Kingdom.
