Hydrogen Sulphide Sample Clauses
The Hydrogen Sulphide clause sets out the responsibilities and procedures related to the presence of hydrogen sulphide (H2S) in operations, typically in oil and gas contracts. It usually details safety measures, monitoring requirements, and notification obligations if H2S is detected above certain thresholds, and may specify the allocation of costs for handling or mitigating H2S. This clause is essential for ensuring the safety of personnel and equipment, as hydrogen sulphide is a hazardous gas, and for clarifying how risks and responsibilities are managed when H2S is encountered during operations.
Hydrogen Sulphide. H2S shall be continuously monitored by automatic instruments complying with ASTM D4084 (Lead acetate reaction rate method). N2, O2, Ar & CO2 shall be continuously measured by a GC with a lower detection limit not greater 0.005 % mole, using Helium as a carrier and a suitable column to split N2 and O2. The limiting value for Oxygen in Table 1 is required during normal operations. Higher values are allowed during commissioning of new pipelines.
Hydrogen Sulphide. The gas will not contain hydrogen sulphide in concentration greater than 5 mg/m3.
Hydrogen Sulphide. Tests to determine hydrogen sulphide content shall be made whenever necessary, but not oftener than two (2) times during any calendar year, to determine whether the gas meets the requirements of Article VII, Section 1 (d) hereof. Such test shall be made at the expense of the Buyer. Seller shall have the right to witness and verify all tests.
Hydrogen Sulphide. Product shall not contain more than twenty (20) parts per million, by weight, of hydrogen sulphide.
Hydrogen Sulphide. The gas will not contain hydrogen sulphide in concentration greater than 10 milligrams per cubic metre (10mg/m3). Test method: ASTM D 2725 Hydrogen sulphide content by methylene blue method.
Hydrogen Sulphide. The level of hydrogen sulphide in the [ ] shall not [ ]
Hydrogen Sulphide. The Gas shall not contain more than four (4) parts per million of hydrogen sulphide per hundred (100) cubic feet as determined by a method generally acceptable for use in the gas industry.
