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.
