    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.

    Frequently Asked Questions — THT Gas Odorant (Tetrahydrothiophene)

    Global Chemicals LLC supplies tetrahydrothiophene (THT) odorant in sealed 208 L drums with batch CoA and SDS, delivered to gas utilities and industrial operators across Oman and exported GCC-wide. THT is a Class 3 flammable liquid with a strong odour — we ship it under ADR-compliant hazmat transport with trained drivers. Send your annual volume and delivery point for pricing.

    THT resists oxidation and adsorbs less onto pipe walls and soil, so its odour intensity stays stable along long distribution networks — the reason most city-gas grids specify it. Mercaptan blends (e.g. TBM-based) have a lower odour threshold per mg but fade faster in some conditions. The network's odorization philosophy and regulator requirement decide; we supply THT and can advise on blend specifications.

    Most networks odorize at 10–25 mg of THT per standard cubic metre of gas, tuned so gas is detectable by smell at one-fifth of the lower flammability limit, per the applicable gas code. Dosing is set on injection skids proportional to flow; our technical team can review your skid specification and detectability target.
