    THT Gas Odorant (Tetrahydrothiophene)

    C4H8S

    Product Overview

    Tetrahydrothiophene (THT) odorant for natural gas and fuel-gas leak detection — 208 L drums with CoA, supplied in Oman & GCC.

    Detailed Description

    THT gas odorant supplier in Oman — Global Chemicals LLC supplies tetrahydrothiophene (THT), the standard odorant for natural gas networks, to gas distribution companies, city-gas projects, and industrial fuel-gas operators across Oman and the GCC. Natural gas is odourless; THT gives it the characteristic warning smell so leaks are detected at concentrations far below the flammability limit. THT is favoured over mercaptan blends for pipeline networks because of its oxidation stability and low soil adsorption, giving consistent odour intensity along long distribution runs. Supplied at ≥99% purity in sealed 208 L steel drums with nitrogen blanket, batch Certificate of Analysis, and GHS-compliant SDS. Handling guidance and dosing-skid compatibility information available from our technical team; typical odorization rates run 10–25 mg/m³ of gas, set to the local regulator's detectability requirement.
