Absorber of hydrogen sulfide and mercaptans Paragroup PM1758

The absorber of hydrogen sulfide and mercaptans ” PARAGRUP PM 1758″ is a specially selected water-soluble composition of condensation products of amines with aldehydes of various concentrations and is intended for binding hydrogen sulfide and acidic mercaptans in oil and oil products, gas and water environments at oil, gas, gas condensate and oil refineries.

The absorber ” PARAGRUP PM 1758″ is produced in two grades A and B in accordance with the current technical conditions TU 2416-066-17423242-2012.

Oil preparation


In order to increase the contact time of the reagent with hydrogen sulphide and mercaptans, ” PARAGRUP PM 1758″ 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 ” PARAGRUP PM 1758″ 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 70-90C 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.
