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.
