DMC PROCESSES FOR OIL AND GAS CONDENSATE TREATMENT FOR HYDROGEN SULFIDE AND MERCAPTANS

Oil treatment using DMC processes:

• reases feed corrosivity two-fold;
•  Enables to produce liquefied hydrocarbon gases (LHG) without subsequent desulfurization (if no secondary С1-С2 mercaptans are formed as a result of other sulfur compounds decomposition during oil processing).

DMC-1 process

For treating light oils and gas condensates for hydrogen sulfide (from 100 to 5 ppm) and low molecular weight С1-С2 mercaptans (from 600 tо 20 ppm).

DMC-1M process

For selective treating of heavy oils and gas condensates for low molecular weight С1-С2 mercaptans (from 300 to 20 ppm) and hydrogen sulfide (from 100 tо 5 ppm) on oil fields.

DMC-1MA process

The most efficient and energy-conserving process for treating oil with high hydrogen sulfide content (from 500-700 ppm tо 5 ppm) is liquid-phase oxidation using aqueous-ammonia solutions of IVKAZ catalyst.

ПРОЦЕСС ДМС-2

Используется для селективной очистки легкой нефти от сероводорода и низкомолекулярных меркаптанов С₁–С₃ без контакта нефти с воздухом. Установки ДМС-2 введены в эксплуатацию путем реконструкции установок ДМС-1.

DMC-3 process

For treating oils and gas condensates for hydrogen sulfide (from 100 tо 5 ppm) and low molecular weight С1-С4 mercaptans (from 4000 tо 50 ppm)

Why not to use formaldehyde-based adsorbents (scavengers) of hydrogen sulfide and mercaptans?
