Improved Process аnd Equipment Engineering Services

NIPI ONGM provides the following science-based support and guidance for downstream processes involving hydrocarbons gathering, treatment and refining:

  • developing Process Procedures to design and upgrade oil and gas gathering and transportation facilities;
  • determining process parameters to design/select tanks, vessels, columns and heat-exchangers;
  • developing PFDs and equipment for oil, gas and wastewater gathering, treatment and transportation, for associated gas utilization and for reservoir stimulation by gas and WAG injection;

We develop improved / advanced technologies covering:

  • oil-water emulsion separation;
  • techniques to reduce loss of light-end hydrocarbons;
  • H2S removal from gas and conversion to elemental sulfur;
  • chelated iron liquid redox processes to remove H2S from gas;
  • adsorption processes to remove H2S and mercaptans from gas using zeolites, activated carbon, solid sorbents based on iron compounds;
  • mercaptans removal from gas using alkaline reagents;
  • sour gas treatment for re-injection;
  • dehydration of hydrocarbon gases using solid sorbents (silica gel, zeolites);
  • membrane technologies for gas treatment;
  • gas condensate stabilization;
  • producing propane/butane mixtures , natural gas liquids, different light hydrocarbon fractions;
  • gas condensate stabilization;
  • increasing the methane number of fuel gas produced from associated gas;
  • methanol generation;
  • Claus sulfur recovery process;

Claus tail gas treatment processes, including:

  • processes based on H2S oxidation to elemental sulfur through a direct air-based oxidation process;
  • processes based on H2S + SO2 reactions involving solid catalysts;
  • processes based on capturing sulfides;
  • elemental sulfur recovery process from SO2-containing tail gases by means of a high temperature and catalytic reduction of SO2 with methane;
  • liquid sulfur degassing, sulfur granulation, ground sulfur production, block sulfur melting and liquid sulfur filtration processes.
  • disposal of NH3-containing H2S gas streams produced during sour waste stripping process at SRU;
  • sour water stripping to separate process water flowing from different sections of the plant from dissolved H2S and NH3 for subsequent recycling.
