Hydrogen sulfide absorber Paragroup PS1657

Hydrogen sulfide absorber Paragroup PS 1657 is a water-alcohol solution of triazines of various concentrations and is designed to bind hydrogen sulfide and acidic mercaptans in oil and oil products, gas and water media at oil, gas, gas condensate production facilities and at oil refineries.

The absorber “Paragroup PS 1657” is produced in three grades A, B and C in accordance with the technical specifications TU 2458-007-17423242-2014.

Oil preparation


In order to increase the contact time of the reagent with hydrogen sulfide (mercaptans), the absorber of hydrogen sulfide ” Paragroup PS 1657″ should be supplied as early as possible to the system with the processed product. The reagent can be injected either continuously or periodically. The supply of the hydrogen sulfide absorber must be carried out using dosing pumps. However, in any case, intensive mixing of the reagent with the oil product must be ensured.


The efficiency of the introduction of the absorber ” Paragroup PS 1657″ depends on the degree of distribution of the reagent in the medium of the processed product. This is especially important for viscous oil products (fuel oil, boiler fuels). Heating such oil products to 50-60C before adding the additive significantly improves the effect of the absorber. Depending on the specific conditions of use, the dosage of the absorber can vary from 5 to 15 g per 1 g of hydrogen sulfide.
