Caustic soda flakes for petroleum refining

How the industry uses caustic soda flakes

Refineries use sodium hydroxide to wash acidic impurities out of hydrocarbon streams — mercaptans (sulphur compounds that cause odour and corrosion) and naphthenic acids. Oilfield service companies also use caustic to control the pH of drilling muds.

• Caustic washing (sweetening) of LPG, gasoline and kerosene fractions
• Removal of naphthenic acids from crude oil and distillates
• pH and alkalinity control of water-based drilling muds
• Neutralisation of acidic gases and equipment cleaning in turnaround work

What to specify when you buy

• Assay 99% min — spent-caustic volumes scale with dilution; strong, consistent feed keeps waste down.
• Low carbonate — carbonate reduces the treating capacity of the lye and accelerates fouling.
• Full dangerous-goods documentation — refineries and oilfield contractors audit supplier paperwork; every shipment of ours travels with COA, MSDS and Class 8 transport documents.

Recommended supply

Refinery and mud-company buyers normally take 99% min flakes in 25 kg bags (offshore and remote sites) or jumbo bags (refinery make-up). Mention HSE documentation needs in your enquiry.
