Absorber of hydrogen sulfide and mercaptans Paragroup PS1650

The absorber of hydrogen sulfide and mercaptans “PARAGROUP PS 1650” is a water-alcohol solution of triazines of various concentrations. The absorber is designed to bind hydrogen sulfide and acidic mercaptans in oil and oil products, including gas condensate and residual oil products, as well as in gas and water environments at oil, gas, gas condensate production facilities and at oil and gas processing enterprises, as well as at points of transshipment of oil products and crude oil in ports.

The absorber ” PARAGROUP PS 1650 ” is produced in two grades K and C in accordance with the current technical conditions TU 2458-083-17423242-2013, rev. 1.2.

Oil preparation


In order to increase the contact time of the reagent with hydrogen sulphide and mercaptans, ” PARAGROUP PS 1650 ” should be supplied as early as possible to the system with the processed product. 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 of hydrogen sulfide and mercaptans ” PARAGROUP PS 1650 ” 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 70-90 ° C 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 4 to 8 g per 1 g of hydrogen sulfide.
